adamdunkels	952dfc9384	Rework of the CSMA layer: instead of using one timer per packet, the module now uses one central timer and a queue of outgoing packets. This helps to keep packets in order, which is extremely useful for TCP transfers, and reduces the amount of congestion since consecutive packets now are spaced in time if there is a collision. Based on the observations and ideas of Simon Duquennoy.	2010-12-14 07:57:14 +00:00

adamdunkels	c19a967973	Bugfix: with the recent bugfixes, it was no longer possible to turn duty cycling back on after it had been turned off	2010-12-07 23:12:54 +00:00
joxe	e1fbb9bba0	changed neighbor state callbacks to occur only at add and remove	2010-12-07 10:36:03 +00:00
nvt-se	b2a28e6fc3	Fixed error reported by Pieter Agten. The reachable time is specified in milliseconds, and must thus be divided by 1000.	2010-12-06 09:48:48 +00:00
adamdunkels	4c9793f428	Let ContikiMAC remember the state that the radio should have when duty cycling is turned off. This fixes a bug in which the radio was turned on after sending, even when NETSTACK_RDC.off(0) was enabled.	2010-12-06 09:08:22 +00:00
adamdunkels	433d42e170	Bugfix: if the cc2420_cca() function wasn't able to turn on the radio properly, it should turn it off again if it was off before.	2010-12-05 00:14:24 +00:00
dak664	f34e5ec798	Convert implicit printf to PRINTF	2010-12-04 21:06:04 +00:00

adamdunkels	2f66db3ded	Added a debug mode that keeps track of where individual queuebufs are allocated, which is useful when debugging queuebuf leakage problems.	2010-11-25 08:43:59 +00:00
nifi	3bd78893e5	Renamed nullrdc to nullrdc-noframer and nullrdc-framer to nullrdc. ... nullrdc (previously nullrdc-framer) is now a RDC implementation that does not do any radio duty cycling but supports link layer addresses and frame format via framer (for example 802.15.4). nullrdc can now be used in the same way as contikimac, xmac, etc. nullrdc-noframer (previously nullrdc) is a null RDC implementation that does not do any radio duty cycling, does not add any header of its own to the packets, and does not support link layer addresses.	2010-11-23 18:11:00 +00:00
dak664	62d7832fff	Fix compiler warning and possible bug	2010-11-13 16:37:42 +00:00
nifi	05d78522d3	Added MAC-layer duplicate message suppression when using 802.15.4 auto ack	2010-11-12 12:53:16 +00:00
nvt-se	1168703506	Minor clarifications in the code and comments. Integrated atches from Frederic Sureau: 1. copy_buf is now an ordinary char pointer. 2. Read directly from a file that is not modified. This reduces the code size when COFFEE_MICRO_LOGS is set to 0. 3. Update the file end value each time it is changed in case a log merge operation occurs later. 4. Avoid possible alignment problem in reading from the dummy_space area when calling cfs_readdir.	2010-11-11 13:08:23 +00:00

adamdunkels	f5031861ac	When IPv6 ND kicks in, the packet that caused the ND can either be dropped or saved in a buffer to be send when the NS reply returns. This commit reimplements the buffer management to avoid having one buffer per neighbor, but instead use a buffer pool from which buffers can be allocated for different neighbors.	2010-10-28 15:42:56 +00:00
adamdunkels	677575fc8c	Rewrote proactive link estimator to be invoked randomly instead of triggered by an empty queue; this makes network bootups because nodes are not synchronized	2010-10-28 15:36:02 +00:00
joxe	932fed8cc7	improved ETX calculation	2010-10-28 08:54:54 +00:00

adamdunkels	77ecfb0366	Rewrote parts of the retransmission logic so that collect is robust against the situation where the MAC layer will fail to callback after a packet has been transmitted.	2010-10-24 21:08:19 +00:00
adamdunkels	8fa7bf6c31	Always restore the queuebuf to the packetbuf before calling the upper layers. Reduce the waiting time between successive MAC layer retransmissions.	2010-10-24 21:07:00 +00:00
adamdunkels	73f5535754	Made the guard time slightly more conservative - found an occasion where this was needed	2010-10-24 21:06:17 +00:00
adamdunkels	8f8741c7f0	Small style fixes	2010-10-24 21:05:42 +00:00
adamdunkels	fd4c0e64aa	Removed old unused files rand.[ch]. By default, Contiki uses the libc implementations of the rand() and srand() functions.	2010-10-24 21:02:23 +00:00
nvt-se	00a000cca0	Print the rank correctly in the debug output.	2010-10-22 15:40:10 +00:00

nvt-se	6e28b1d3fb	Reduced ETX_LIMIT in order to avoid overflows. Removed ETX_LOSS_PENALTY and set packet_etx to ETX_LIMIT instead upon packet loss.	2010-10-21 19:46:21 +00:00
adamdunkels	9cb830ed37	Timing bugfix in the waiting period between channel samples to check if the coast is clear before sending a packet.	2010-10-20 22:25:24 +00:00
adamdunkels	06123fefe2	Defensive programming: make sure that a process is actually running before we try to kill it.	2010-10-20 22:24:46 +00:00
adamdunkels	3ffcff0656	Added mechanisms for explicit de-synchronization of synchronized neighbors. Added link-layer ACKs. Fixed bugs with MAC-layer interaction. Now seems to work somewhat (didn't work at all before, in some cases), but there are still problems with packet loss.	2010-10-20 15:23:43 +00:00
adamdunkels	5585d72c86	A simple but substantial change: uIP used the htons()/HTONS() macro ... functions for converting between host and network byte order. These names are the de facto standard names for this functionality because of the original BSD TCP/IP implementation. But they cause problems for uIP/Contiki: some platforms define these names themselves (Mac OS, most notably), causing compilation problems for Contiki on those platforms. This commit changes all htons to uip_htons instead. Same goes for htonl, ntohs, and ntohl. All-caps versions as well.	2010-10-19 18:29:03 +00:00
adamdunkels	34cba78ca8	Bugfix: bump advertisements only when a parent changes, not because of an upstream parent change	2010-10-19 07:34:29 +00:00
nifi	e2b4956a7f	Bug fix: release the packet and notify the sender if RDC returned an error	2010-10-14 19:08:39 +00:00
oliverschmidt	2f89e69ff7	Fixed build for platforms which use the default value for QUEUEBUF_NUM.	2010-10-12 19:51:28 +00:00
adamdunkels	020da4e8ba	Added a function for obtaining beacon intervals	2010-10-11 23:44:24 +00:00
adamdunkels	ec716ea62d	Do not reduce transmission interval, unless explicitly told so with the bump flag	2010-10-11 23:43:01 +00:00
adamdunkels	37adf130b4	Rewrite of the congestion logic. A node now report it being congested ... when half the transmission queue is full. When a neighbor is heard to be congested, the rtmetric of that node is inflated to avoid sending more traffic in its direction. Fixed problems with beacon intervals: intervals are now not reduced when a path gets significantly worse, only when they get better.	2010-10-11 23:42:01 +00:00
adamdunkels	d821ba5e22	Added a lifetime for link estimates: if they are too old, they are ... reset so that a new probing period can produce more up-to-date estimates. Added a congestion mechanism whereby a neighbor can be marked as being congested for a period of time, during which the ETX for the neighbor will be artificially inflated.	2010-10-11 23:38:46 +00:00
adamdunkels	5eb4a0fe8d	Rewrote the initial link estimate logic: link estimates are now ... computed only over the actual samples, not over the entire buffer. Also, the initial link estimate is much more conservative now (16 transmissions) to favor links that have been probed, and which therefore are likely to have better ETXs.	2010-10-11 23:34:02 +00:00
adamdunkels	0cabe483c3	Don't call sink recv function for zero-size packets, since these most likely are link estimate probes or keepalive packets. Explicitly set eseqno to zero when opening a new connection.	2010-10-07 15:52:28 +00:00
adamdunkels	ad35c54473	Bugfix: when a node's rtmetric was lower than SIGNIFICANT_RTMETRIC_PARENT_CHANGE, its beacon timers would always be bumped to its lowest value	2010-10-05 20:06:47 +00:00
adamdunkels	52e9a6f1fb	Turned the DRAW_TREE debug flag off by default	2010-10-04 22:36:47 +00:00
adamdunkels	65d640ac53	Several bugfixes to the proactive link estimate maintenance code, which is now enabled by default. Simplified DRAW_TREE code for drawing routing graph in Cooja. Added routing metric penalty to parents that are congested or that drop packets.	2010-10-04 20:27:50 +00:00
adamdunkels	212e73faa6	Removed old netsim code. Added a function for obtaining the packet attributes of a queuebuf packet.	2010-10-04 20:26:01 +00:00
joxe	4f3fc1c404	fixed xmac to use new channel check define name	2010-10-03 22:46:53 +00:00
adamdunkels	ceebd7020a	Bugfix: the return value sometimes was wrong when a collision was detected.	2010-10-03 20:39:24 +00:00
adamdunkels	ae88ed04f1	Moved the definition of the channel check rate used by the radio duty ... cycling layer. This definition was previously held in net/mac/mac.h, with the name MAC_CONF_CHANNEL_CHECK_RATE. But since the rate is used by the radio duty cycling layer, it makes more sense to change its name to reflect this. Also, the configuration option should be tied to the netstack configuration instead. So the new configuration option is called NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE.	2010-10-03 20:37:32 +00:00
adamdunkels	40583fe112	Removed the polite announcement code, since it was not used, and enabled the broadcast announcement code by default. Increased the default intervals for broadcast announcements.	2010-10-03 20:10:22 +00:00
adamdunkels	605392522f	Bugfixes and improvements: rtmetrics are now 16-bit clean. Added experimental feature that proactively probes neighbors that have not yet been tried out, in order to get an initial ETX for them.	2010-10-03 20:08:44 +00:00
adamdunkels	d0579c8a81	Cleaned up the collect neighbor management code	2010-10-03 20:07:10 +00:00
adamdunkels	b23a364397	rtmetric values should always be computed as 16-bit values	2010-10-03 20:06:25 +00:00
nvt-se	909569f834	Must check if load_file succeeded	2010-10-01 20:14:14 +00:00
adamdunkels	32ba90ea4c	Bugfix: make sure that neighbor exists before attempting to update tx ... count.	2010-09-28 06:53:02 +00:00
joxe	77c5187a2e	fixed bug where context is null but still referenced	2010-09-23 19:57:50 +00:00
joxe	494d2a3073	only compare with global addresses when selecting source for a specific destination	2010-09-23 18:17:27 +00:00
nifi	e242fb28bf	Reverted radio API change in CC2420 (not yet fully integrated with Contiki core)	2010-09-23 08:26:06 +00:00
adamdunkels	eed22a6f3c	A number of changes to the collect code: ... * Added an optional "keep alive" mechanism whereby an idle network is periodically probed by dummy packets to maintain a recent quality metric when there is no traffic. * Bugfix in when new routing metrics should be advertised * Rewrote the ACK logic so that a queuebuf is not allocated for each ack, only for those acks generated by the sink node. * Updated the wrap-around logic for sequence numbers: when a sequence number wraps, it won't go back to 0. Instead, it wraps to 128. This allows us to understand when a node has rebooted: when its seqno is < 128, it has recently rebooted.	2010-09-22 22:08:08 +00:00
adamdunkels	2cae71e89b	Added a function for obtaining the link estimate and rtmetric for a neighbor	2010-09-22 22:04:55 +00:00

nifi	095f700b63	Moved down inclusion of rtimer-arch.h to allow rtimer_clock_t to be used in rtimer-arch.h	2010-09-13 20:46:02 +00:00
adamdunkels	eb58968459	Added a timer to each phase structure that keeps track of for how long ... a particular receiver has not ACKed packets. After some time (currently 16 seconds), the sender will begin sending full strobe periods again.	2010-09-13 13:39:05 +00:00
adamdunkels	3ae774c91a	Added a way to for specifying lists as parts of structs. These lists ... must be initialized with a special LIST_STRUCT_INIT() call before using.	2010-09-13 13:31:00 +00:00
adamdunkels	591766e663	Significant improvements to the Collect protocol: ... * Loop detection and untangling. Now uses in-band loop detection that works. * Link quality estimation. Now starts with a conservative / pessimistic estimate for new links. * Retransmissions. MAC layer and network layer retransmissions are now decoupled. * Loss handling. Deals better with losses now. * Concurrent applications. Each connection now maintains its own neighbor table with separated cost to sink estimates for each connection.	2010-09-13 13:28:14 +00:00
oliverschmidt	a0b8927777	Allow to exit the process owning the foreground window by pressing ctrl-c. This is especially useful if there's no closebutton on the window frames (or no windows at all).	2010-09-09 20:21:26 +00:00
adamdunkels	4e0744954a	Rewrite of important parts of the Collect logic: link estimation ... calculation and parent selection. This fixes a severe bug that caused loops when packets were erroneously retransmitted due to ACK loss.	2010-09-08 19:21:45 +00:00
nifi	f05952c926	Changed packet id to use 8 bit instead of 4 bit	2010-08-31 13:14:49 +00:00

dak664	12479c32bc	Fix compiler warnings	2010-08-01 21:18:07 +00:00
oliverschmidt	89f6235c13	Using wherex() to determine the length of the string printed with cputsn() fails if the right edge of the screen was reached as wherex() then returns 0. ... Therefore we rather count the chars actually printed in cputsn() and return that value thus avoiding usage of wherex() in those scenarios altogether.	2010-07-20 22:19:23 +00:00
nvt-se	11760059d3	The second predicate is not needed.	2010-07-03 23:52:02 +00:00

oliverschmidt	e5665fb968	The recent change turning uip_buf from an array to a pointer seems a quite heavyweight way to have the uip_buf alligned to a 32-bit boundary. Contiki is - still - supposed to be portable across a wide range of toolchains - therefore it i.e. intentionally doesn't use C99 features. From that perspective it seems questionable if all toolchains are able to optimize away the overhead imposed by an "unnecessary" indirection to access uip_buf - and uIP consists mostly of accesses to uip_buf. Even if the future is supposed to bring support for multiple uip_bufs which would turn the uip_buf pointer from a mere workaround to an neceesary element on can still presume that there will be targets with resources limited in a way prohibiting the use of several uip_bufs. So at least for those targets will still be a usecase for a "plain", not indirected uip_buf. ... Therefore it seems reasonable to allow to stay with the "plain" uip_buf at compile-time.	2010-05-08 07:23:55 +00:00

adamdunkels	a4f9e62295	Added a parameter to collect_open() that specifies whether or not the node should be a router for packets, or only an originator of packets. Updated the collect module to the new annoucement API.	2010-03-25 08:51:07 +00:00
adamdunkels	2559e27414	API change to the announcement module: an annoucement can now be registered without a value. Such announcements are never transmitted to neighbors, until the announcement's value is set.	2010-03-25 08:49:56 +00:00
adamdunkels	4d68bdf74b	Bugfix and addition by Dogan Yazar: psock_readbuf() shouldn't wait for a full buffer (which might never happen); a new function for sending strings that batches data and sends full buffers instead of individual strings.	2010-03-24 21:03:32 +00:00

adamdunkels	efeb9944fa	Increase the required non-activity periods before turning off the radio; remove the strict phase requirement (which messes up things with low-power streaming)	2010-03-17 16:35:52 +00:00

adamdunkels	b1feac5a00	Bugfixes in low-power streaming mode, and re-added support for announcements. These now use the low-power streaming mode so that active listening for announcments have a radio duty cycle of 16% rather than 100%	2010-03-16 18:11:13 +00:00
adamdunkels	67b0170a43	Bugfix: don't care about FIFOP when reading a packet; if the radio rx had been turned off before a packet was read, FIFOP would be zero and the packet would be trashed	2010-03-16 18:10:09 +00:00

adamdunkels	7bab9316da	Two major changes: ... * Low-power streaming. Experimental support for a low-power mode which allows rapid exchange of packets with a 16% duty cycle. Does not seem to function correctly yet though. * Phase locking. When the phase of a neighbor has been detected, the sender assumes that the neighbor will keeps it phase and does not send more strobes than necessary to hit the receiver's channel check - even if the receiver does not acknowledge the reception of the strobes when it should have been awake. Instead, the sender stops strobing and tries again at a later time.	2010-03-14 22:59:23 +00:00
adamdunkels	0035a70537	Reworked the locking code, which seems to fix a few bugs caused by the interaction with contikimac. Contikimac performs a CCA check in a preempting rtimer, which requires underlying code to properly call the GET_LOCK() macro. This fix seems to solve most problems, but there may be others left.	2010-03-14 22:45:20 +00:00
oliverschmidt	def540e6c0	Avoid newlines in macro expansions as cc65 doesn't support them between the macro name and the open parenthesis of the arguments. ... There were btw other even longer lines with expansions of the same macro already present.	2010-03-14 12:13:54 +00:00

adamdunkels	7165a3866f	Significant rework of the Contiki data collection protocol: ... * the new version makes use of MAC-layer feedback so that bad paths can be identified quicker and then avoided. * the new code uses transport layer ACKs that contain feedback from the collect protocol: when a packet cannot be forwarded due to lack of resources, the ACK contains a flag that indicates that the packet could not be forwarded. ACKs also contain the routing metric of the sender, which improves agility in face of rapid path changes. * loop detection and management has been improved: with higher path metric agility, the system is more prone to short-lived routing loops. Instead of dropping looping packets, the new version adjusts the routing metric for the routes that exhibit loops so that the risk for future loops is reduced. * make use of packet attributes to inform the MAC layer of how many times packets should be retransmitted.	2010-02-28 09:18:01 +00:00

adamdunkels	ed52586e18	Rework of parts of the ContikiMAC code based on input from experimental results. When channel check is triggered because of a false positive, the new version checks the radio several times to make sure that there really is an incoming packet. Otherwise, the radio is switched off. Cleaned up and removed old unused code. Added a few temporary debugging mechanisms and functions.	2010-02-23 18:49:05 +00:00

adamdunkels	0c4c88ae66	Improved per-packet power profiling: if a packet is retransmitted, the new energy is added to the old energy so that it is possible to measure the full energy for all transmissions of the packet	2010-02-23 18:39:00 +00:00
adamdunkels	ca0417a923	Added the MAC layer callback functionality so that the Rime network layer gets information from the MAC about the status of sent packets: were they successfully transmitted, or was there a collisions? How many retries were there?	2010-02-23 18:38:05 +00:00
adamdunkels	f10eedab3e	Added debug printout	2010-02-23 18:37:15 +00:00
adamdunkels	2d13fecea7	Improved backoff management: timer is now doubled on every transmission, until the using module calls the neighbor_discovery_start() function again. Don't cancel the transmission even if a lower value arrives (this fixes a problem with multi-hop ETX propagaion).	2010-02-23 18:36:50 +00:00
adamdunkels	0eade2886c	Better loop handling: when a loop is detected, the neighbor to which the packet was originally sent gets an inflated ETX; made sure that collect without announcments work; increased timeouts, to work nicer in larger networks	2010-02-23 18:35:23 +00:00
adamdunkels	a4d9d6651b	Added the option to specify the old value to observers so that they can determine if the announcement should be sent out quicklier than otherwise	2010-02-23 18:32:44 +00:00
adamdunkels	b746b7fc06	Reworked the Rime/Chameleon interface so that packets now always hit Rime before Chameleon. Chameleon is now only called by Rime. This makes packet sniffing easier, and allows for sniffing packets after their header has been processed by Chameleon, thereby making per-packet power profiling much easier to implement	2010-02-23 18:29:53 +00:00

adamdunkels	e34eb54960	A work-in-progress rework of the Contiki MAC and radio layers. The ... main ideas are: * Separates the Contiki low-layer network stack into four layers: network (e.g. sicslowpan / rime), Medium Access Control MAC (e.g. CSMA), Radio Duty Cycling RDC (e.g. ContikiMAC, X-MAC), and radio (e.g. cc2420). * Introduces a new way to configure the network stack. Four #defines that specify what mechanism/protocol/driver to use at the four layers: NETSTACK_CONF_NETWORK, NETSTACK_CONF_MAC, NETSTACK_CONF_RDC, NETSTACK_CONF_RADIO. * Adds a callback mechanism to inform the MAC and network layers about the fate of a transmitted packet: if the packet was not possible to transmit, the cause of the failure is reported, and if the packets was successfully transmitted, the number of tries before it was finally transmitted is reported. * NULL-protocols at both the MAC and RDC layers: nullmac and nullrdc, which can be used when MAC and RDC functionality is not needed. * Extends the radio API with three new functions that enable more efficient radio duty cycling protocols: channel check, pending packet, and receiving packet. * New initialization mechanism, which takes advantage of the NETSTACK #defines.	2010-02-18 21:48:39 +00:00
adamdunkels	f8c804e28b	ntikiMAC: a new radio duty cycling mechanism that uses a combination ... of link-layer and MAC-layer mechanisms to achieve a very low power consumption: during idle listening the radio is switched off between 99.2% and 99.6% of the time. One unicast transmission typically adds between 0.07% and 1.2% additional radio time, depending on packet size. ContikiMAC uses the standard IEEE 802.15.4 message format and adds no additional headers. ContikiMAC is simple: it uses periodic two-shot channel sampling during idle listening to keep the radio on-time down. Transmissions are done with repeated transmissions until a link-layer ACK is received.	2010-02-18 21:26:15 +00:00

adamdunkels	d67d1f7340	Major bugfix, found by Raimondas Sasnauskas: the TCP periodic timer was not started when a new connection request arrived. If there were no other active TCP connections, this means that the SYNACK would never be retransmitted, potentially leading to a forever stale TCP connection.	2010-02-09 12:58:53 +00:00

adamdunkels	b6647b5630	Turns out that with cxmac, clearing the header after sending a packet is not enough to make fragmentation work. Instead, we allocate a queuebuf and restore the packet after from the queuebuf after sending it.	2010-02-06 09:42:49 +00:00
adamdunkels	494e692d0b	Bugfix: clear the header after sending a packet solves a problem with fragmentation; also prod the watchdog since fragment transmissions can take a long time with some low-power MAC protocol	2010-02-06 07:49:58 +00:00

adamdunkels	1a13d25d33	Revised version of the X-MAC implementation that uses a ctimer instead ... of an rtimer for the periodic radio duty cycling. The benefit of this implementation is that it leaves an rtimer free for user tasks. The drawback is a slightly higher idle power consumption.

adamdunkels	9d26bd663e	A new optimization to X-MAC: senders now keep track of when neighbors ... last were known to be awake. When sending a packet, a sender does not start to send strobes until the neighbor is expected to be awake. This reduces power consumption for senders and decreases the contention in the network as there are less packets in the air.

nvt-se	1425537a13	Introduced two garbage collection mode: greedy and reluctant. ... The greedy GC mode attempts to erase as many sectors as possible, and it is therefore a slow operation, since the flash driver must wait for about a second after erasing one sector. The former behavior was to always do a greedy GC if file reservations fails due to lack of space. The new reluctant GC stops after erasing one sector, and therefore we often do not have to wait if there is no file system operation in the time while the sector is being erased. We call the garbage collector using this mode when removing a file that is not a micro log file, since the remove function is called recursively for micro log files that are erased because the corresponding ordinary file is erased. This change increases the coffee test (examples/sky/test-coffee.c) speed from 9 to 5 seconds.	2009-04-02 11:22:23 +00:00

oliverschmidt	a7cb609321	With dynamic loading enabled the function ctk_textentry_input_null() lives in the persistent core while the macro CTK_TEXTENTRY() is typically used in loadable modules. So ctk_textentry_input_null() needs to be dynamically resolved. ... On Win32 dynamic resolving isn't done by patching the dynamically loaded segments. Rather the code generated by the compiler for accessing symbols declared with __declspec(dllimport) is implicitly modified to actually go through pointer dereferenciations. The dynamic linker only initializes this pointers. But with the symbol ctk_textentry_input_null becoming a pointer to a function it isn't a constant anymore and so it can't be used as initializer element - and thus breaking CTK_TEXTENTRY(). So the only viable solution seems to stick to the inversally available NULL pointer on Win32. But if there's an ugly #ifdef <platform> necessary anyway than it seems resonable to classify ctk_textentry_input_null as the special case and therefore use #ifdef SDCC: - It saves some bytes on all non-SDCC platforms - Is matches the exsisting inline documentation	2009-02-28 10:43:30 +00:00

adamdunkels	be846d8c90	A new experimental network primitive called an 'announcement'. An ... announcement is an (ID, value) tuple that is disseminated to local area neighbors. An application or protocol can explicitly listen to announcements from neighbors. When an announcement is heard, a callback is invoked. Announcements can be used for a variety of network mechanisms such as neighbor discovery, node-level service discovery, or routing metric dissemination. Application programs and protocols register announcements with the announcement module. An announcement back-end, implemented by the system, takes care of sending out announcements over the radio, as well as collecting announcements heard from neighbors.	2009-02-05 19:32:01 +00:00

nifi	d76474bc13	Changed energest_type_time() to first update the total time, if the device ... is currently active, before returning the total time. Added energest_flush() that updates the total time for all currently active devices. It should be called periodically to avoid the time to overflow for devices that are active for long periods of time.	2008-06-02 13:12:07 +00:00
adamdunkels	41f2443c02	Removed old unused documentation that messed up Doxygen	2008-05-27 14:00:09 +00:00

adamdunkels	1feb4fe3cb	Removed call to tcpip_set_forwarding() - the UIP_CONF_IP_FORWARDING configuration option is used instead	2008-05-14 19:20:28 +00:00
adamdunkels	31ea41d8db	Changed the name of UIP_CONF_TCP_FORWARD to UIP_CONF_IP_FORWARD since forwarding is done at the IP level	2008-05-14 19:19:28 +00:00

oliverschmidt	59145615b0	Changed packet forwarding from a runtime option to a compiletime option. This avoids pulling in uip-fw.o if forwarding isn't required (saves > 1400 bytes on 6502 targets). ... *** This change breaks all platforms calling tcpip_set_forwarding() ! These calls were intentionally not removed as they need to be replaced by setting the new compiletime option UIP_CONF_TCP_FORWARD - which should be done by the platform owners. ***	2008-03-29 15:19:25 +00:00

oliverschmidt	2b24ec3189	The cc65 compiler has a bug that doesn't allow to initialize an automatic struct with references to automatic variables. Therefore I changed the timetable used for measuring the timestamping time from automatic to static - which wastes some bytes in the data segment. If this isn't generally acceptable then an #ifdef __CC65__ seems to be the appropriate approach.	2008-02-28 22:43:40 +00:00

adamdunkels	412facb831	This is an initial commit of an implementation of the Chameleon ... architecture for the Rime stack for Contiki. The Chameleon architecture separates the header processing from the Rime protocol logic. Instead of having each protocol create its own part of the packet header, protocols use packet attributes. Before sending a packet, a special Chameleon header processing module creates a packet header from the packet attributes. The same Chameleon module parses incoming packets and creates packet attributes from the header. The details are in our SenSys 2007 paper: Adam Dunkels, Fredrik Osterlind, Zhitao He. An Adaptive Communication Architecture for Wireless Sensor Networks. In Proceedings of the Fifth ACM Conference on Networked Embedded Sensor Systems (SenSys 2007), Sydney, Australia, November 2007. http://www.sics.se/~adam/dunkels07adaptive.pdf This is a rewrite of the code that was developed for the paper.	2008-02-25 02:14:34 +00:00

adamdunkels	436d1f25eb	Added a configuration option for using u32 in the uip_ip4addr_t structure: UIP_CONF_UIP_IP4ADDR_T_WITH_U32	2008-02-24 21:04:15 +00:00

oliverschmidt	8f81934bfd	Since revision 1.11 the usage of the label 'ip_send_nolen' isn't solely depending on UIP_UDP anymore.	2008-02-15 17:12:46 +00:00

oliverschmidt	081d50b878	Reverted part of recent change. The 32-bit member causes 32-bit alignment on 32-bit machines - at least without specific compiler options. That 32-bit alignment causes padding i.e. the ARP structure breaking the existing code.	2008-02-09 16:22:22 +00:00

adamdunkels	29cc2b1266	Updated debug printouts	2008-01-23 16:10:10 +00:00
adamdunkels	f4dd9ccd5b	Rewrote the process code so that initialization events are posted synchronously instead of asynchronously, so that we don't have to explicitly wait for processes to be initialized. This also reduces the size of the event queue by half on the Tmote Sky platform since the queue was maximized during system bootup. This change also prompted an update of the process invokation code to ensure that a process is not invoked again when processing an event. General cleanup of the code also.	2008-01-23 15:18:06 +00:00
adamdunkels	c8dccbbd40	Added a function for converting a timesynchronized time to a local (rtimer) time	2008-01-23 15:07:05 +00:00
adamdunkels	8a9b931a4b	Rewrote most of the X-MAC code to make it easier to follow, debug and modify. Also added an optional, experimental time synchronized addition that makes X-MACs on different nodes explicitly de-synchronized	2008-01-23 15:00:54 +00:00
adamdunkels	2c5964ef55	Changed default transmission behaviour to be to send without checking for channel activity first (in anticipation of radio API change that adds a CCA function to the radio API). General code cleanup. Added optional timetable profiling. Added simple_cc2420_get_channel() function, changed simple_cc2420_set_chan_pan to simple_cc2420_set_pan since we now have a dedicated simple_cc2420_set_channel	2008-01-23 14:57:19 +00:00

adamdunkels	57b54894f8	Removed mistakenly added development files	2008-01-14 16:05:34 +00:00
adamdunkels	34bd11905c	Rewrote the timesynch code to use the Rime sniffer interface instead of the kludge of running timesynch as a MAC layer	2008-01-14 14:50:01 +00:00
adamdunkels	02ee418313	Moving timesynch.[ch] from sys/ to core/net/rime as they have more to do with Rime than with the kernel	2008-01-14 14:22:16 +00:00
adamdunkels	042180c13f	Rewrote the sniffer code to use a list, which makes it possible to add any number of sniffers. Sniffers now can be both for incoming and outoing packets.	2008-01-14 09:42:00 +00:00
adamdunkels	7fcb1f3b2a	Updated debug output	2008-01-14 09:36:35 +00:00
adamdunkels	94f8978443	Rewrote the sniffer code to use a list, which makes it possible to add any number of sniffers. Sniffers now can be both for incoming and outoing packets.	2008-01-14 09:35:53 +00:00
adamdunkels	b26754fd95	Removed unused code	2008-01-14 09:34:33 +00:00
adamdunkels	7b94bfb621	Rewrote the code to use polite broadcasts istead of regular broadcasts. This reduces the amount of broadcast traffic, particularly for dense networks.	2008-01-14 09:34:00 +00:00
adamdunkels	bd125aaac6	Changed the code so that the rtimer is only set from the rtimer (interrupt) code, and not from the non-rtimer code. Removed unused code that was supposed to turn the radio off when a packet for another node was heard (but which didn't really work anyway). Changed default on time to 1/100 seconds, and off time to 1/2 seconds	2008-01-14 09:26:42 +00:00
adamdunkels	28eaf5ee40	Moved C preprocessor concatenation macro to sys/cc.h	2008-01-14 09:22:50 +00:00

adamdunkels	d2be099c0e	Bugfix: queue buffers were not freed when a new packet was sent, leading to memory leakage. Added debug output.	2008-01-08 07:59:51 +00:00

adamdunkels	1640b11972	The radio driver now takes care of adjusting for the transmission time	2008-01-08 07:54:16 +00:00
adamdunkels	88a010acdc	Added a simple sniffer callback, which currently is a hack - a better solution would be a list of sniffers for both outgoing and incoming packets, but this will do for now.	2008-01-08 07:53:02 +00:00
adamdunkels	5b454bbd5f	Added a simple sniffer callback, which currently is a hack - a better solution would be a list of sniffers for both outgoing and incoming packets, but this will do for now. Added trickle, neighbor & route includes.	2008-01-08 07:52:31 +00:00
adamdunkels	b356ebe009	Increased the default input line length from 40 to 80	2008-01-08 07:49:51 +00:00
adamdunkels	25a5434fb5	Sending with interval 0 made explicit	2008-01-07 14:53:04 +00:00
adamdunkels	d33871facc	Bugfix: hops should be at least one for all packets that are sent over the radio	2008-01-07 14:52:23 +00:00
adamdunkels	a0a524e128	Added watchdog_reboot() prototype	2008-01-07 14:42:35 +00:00
adamdunkels	cc6c6eee62	Added prototype for _on() and _off() functions	2008-01-07 14:41:34 +00:00
adamdunkels	d8e84abaae	Made estimation of departure time better by locally measuring the average time per byte and adding this to the incoming timestamp.	2008-01-07 14:08:02 +00:00
oliverschmidt	00d75c8d16	Made use of uip_ipaddr_to_quad().	2008-01-04 23:28:33 +00:00
oliverschmidt	af6d9a59be	Adjusted value (without distinguishing between Ethernet, SLIP, ...).	2007-12-23 20:24:46 +00:00
oliverschmidt	1ecf65d6c2	Allow to implement cfs API on preprocessor level. The benefits are: ... - Less overhead. - Switching implementations without makefile changes. - Compatibility with specific declaration needs. (I.e. the cc65 module loader expects the read() function to be defined as fastcall but that contradicts the cfs API declaration.)	2007-12-23 15:22:33 +00:00
oliverschmidt	a9ebc469b8	Avoid usage of POSIX function names even for static functions as some indirectly included system header might declare them.	2007-12-23 14:56:54 +00:00
oliverschmidt	f67506ba2a	Set truncate flag to make sure that overwriting a existing file doesn't result in a mix of old and new content.	2007-12-23 14:12:44 +00:00
oliverschmidt	8a4e2ec268	Fixed typo.	2007-12-22 12:02:43 +00:00
oliverschmidt	0564cc50fd	Splitted POSIX based cfs implementation to avoid pulling in potentially large POSIX directory I/O functions without needing them at all.	2007-12-21 01:36:01 +00:00
oliverschmidt	878f56837d	Did more aggressive fullscreen ctk codesize optimization. Now ctk draw implementations need adjustment as the struct window member x and y are gone. Another potential optimization would be to remove clipping...	2007-12-20 20:45:06 +00:00
oliverschmidt	1b5ae78a95	Easily avoided double (meant to be a forward ?) definition of timesynch_driver.	2007-12-20 20:30:55 +00:00
adamdunkels	3033b86753	Made the number of routing table entries configurable	2007-12-17 09:20:16 +00:00
adamdunkels	758411d06d	Cleaned up #includes to avoid cyclic dependencies - the Rime includes no longer depend on rime.h	2007-12-17 09:14:08 +00:00
adamdunkels	8287215c82	Removed obsolete, unused files	2007-12-17 09:12:16 +00:00
adamdunkels	d80052c0e7	Removed debug output	2007-12-16 14:48:33 +00:00
adamdunkels	07e2ca9287	Documentation updates	2007-12-16 14:33:32 +00:00
adamdunkels	5c5775e93b	Ensure that receiver_callback is set before calling it	2007-12-16 14:31:43 +00:00
adamdunkels	c948c97b4f	Fixed timestamping to support the simple implicit network time synchronization mechanism	2007-12-16 14:30:36 +00:00
adamdunkels	8bf9a08a70	A simple implicit network time synchronization mechanism	2007-12-16 14:29:56 +00:00
oliverschmidt	4b11df81ba	Mustn't include libconio header as this is just one possible implementation of the conio API (and further code exlusion for fullscreen ctk).	2007-12-16 13:00:51 +00:00
oliverschmidt	dca1f5cc19	Exclude unnecessary code in ctk fullscreen mode.	2007-12-15 22:18:13 +00:00
oliverschmidt	80d47e851f	Have the fullscreen mode (triggered by not setting CTK_CONF_WINDOWS) work with mouse support.	2007-12-15 21:29:46 +00:00
oliverschmidt	9c9e336f45	Some source reformatting.	2007-12-15 21:04:20 +00:00
oliverschmidt	4671ee3d10	Have ctk (at least on conio) work correctly without menus.	2007-12-15 20:46:15 +00:00
oliverschmidt	6fd3b0dbae	Removed CTK_CONF_HYPERLINK from shared code as its use is still unclear (and the implementation was incomplete anyway).	2007-12-15 11:34:59 +00:00
