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	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	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

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
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
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

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	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
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

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	410d860a93	Improved handling of neighbor phase estimation: instead of busy-waiting while waiting for neighbor's phase, the new code schedules a timer just before neighbor wakes up	2010-02-28 20:19:47 +00:00
adamdunkels	e6fceb7200	Added MAC-layer return value to indicate that a packet transmission was deferred	2010-02-28 20:18:30 +00:00

adamdunkels	970a9eb9c7	Increased neighbor lifetime to allow for longer neighbor announcement intervals	2010-02-28 09:19:04 +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	b6b4941871	Made the number of MAC-layer retransmissions configurable on a per-packet basis, via a packet attribute	2010-02-28 08:35:16 +00:00
adamdunkels	ed88f487c8	Improved detection of link-layer ACKs; increased the time ContikiMAC waits when it has detected a link-layer ACK; increased the number of silence periods required to detect a CCA false positive	2010-02-28 08:33:21 +00:00
adamdunkels	fa1a96636e	Bugfix: the compile-time check for UIP_LLADDR_LEN previously generated a run-time error, when it should have generated a compile-time error	2010-02-28 08:30:39 +00:00
adamdunkels	ba0e50a7b7	Set the default number of MAC layer retransmissions for IPv6 packets to 2	2010-02-28 08:29:42 +00:00
joxe	0ab2bc9a31	upgraded sicslowpan to hc-06 - no 48 bit multicast compression support yet	2010-02-25 15:50:58 +00:00
nifi	b50d47fb80	added missing function in sicslowmac_driver	2010-02-23 22:45:11 +00:00
nifi	1cfcc8a73a	Removed the combined name of CSMA and NETSTACK_RDC. The name of NETSTACK_RDC can be accessed separately if needed.	2010-02-23 20:42:45 +00:00
nifi	c20047f657	Changed the network stack to use different structures for the different layers (network_driver, mac_driver, rdc_driver, radio_driver). This helps to avoid incorrect configuration.	2010-02-23 20:09:11 +00:00
adamdunkels	bb62749de7	Made debug printfs optional	2010-02-23 18:49:58 +00:00
adamdunkels	0ab2ba433f	Bugfix: the wrong callback pointer was passed to higher layers.	2010-02-23 18:49:45 +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	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	d8cce42d28	Set the default radio driver to nullradio	2010-02-23 18:28:04 +00:00

adamdunkels	f49ebfe1c4	Temporarily disabled rime route udp because it breaks with newest MAC interfaces	2010-02-18 21:53:08 +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	f5c48751b5	Reworked 802.15.4 header creation and parsing so that it works regardless of the size of the rimeaddr_t typedef	2010-02-18 21:00:28 +00:00

adamdunkels	9bb149ca13	Bugfix by Raimondas Sasnauskas: TCP SYN duplicate receptions in the SYN_RCVD state was not correctly handled	2010-02-15 18:03:07 +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	4a522c96dd	Added debugging statements for packet drops	2010-02-08 21:59:49 +00:00

adamdunkels	671216c558	No need to clear the headers now that we explicitly save a queuebuf when sending fragments	2010-02-06 17:07:43 +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	a68b4c40c4	Added a function to clear only the header part of the packetbuf	2010-02-06 07:48:52 +00:00

adamdunkels	d7b7b05d0e	Moved the neigbor_init() call to the collect module, since it is the only one that currently uses it	2010-02-03 20:38:33 +00:00
adamdunkels	75e1c0c8c7	Include contiki-conf.h to let the MAC channel check rate be configurable	2010-02-03 16:45:12 +00:00

adamdunkels	e419eb3cc5	Retransmit packet if it didn't receive a MAC layer ack	2010-02-03 01:17:54 +00:00
adamdunkels	d68af249ec	Added a MAC layer return value that informs the caller that a packet did not receive a MAC layer acknowledgement	2010-02-03 01:17:32 +00:00
adamdunkels	4bc4f033e8	Increase the trickle resend interval for router advertisements	2010-02-03 01:13:17 +00:00
adamdunkels	181213124b	Added a configuration option for setting the MAC channel check rate (which must be a power of two). The configuration is independent of the MAC protocol.	2010-02-02 23:28:58 +00:00
adamdunkels	f66cd6d44e	Increased the forwarding queue to six packets to improve collection robustness	2010-02-02 21:44:05 +00:00
adamdunkels	901a128e7f	Reconfigured the timeouts to work better on top of a power-cycling radio mechanism	2010-02-02 21:12:29 +00:00

adamdunkels	fcf60e9260	Removed the csma_init declaration in the mac_driver struct since it isn't needed and it breaks sdcc	2010-02-02 20:45:58 +00:00
adamdunkels	cc2be0f111	Remove compiler warnings	2010-02-02 16:33:07 +00:00
adamdunkels	88c661b0c2	Rewrote the netif time code so that is avoids the use of floating point numbers; some code style fixes	2010-02-02 16:32:03 +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. This new version is based on the current rtimer-based X-MAC.	2010-01-31 18:44:23 +00:00

adamdunkels	423e37f426	Added parameter to ipolite that specifies how many dups that are acceptable, before suppressing one's own packet	2010-01-25 13:54:06 +00:00
adamdunkels	0b58ca3b22	Bugfix: split full size TCP segments if they match the MSS definition, not only the buffer size definition	2010-01-25 13:53:15 +00:00
adamdunkels	7615a6cf47	Bugfix by Henrik Mäkitaavola: check that ICMP6 process is defined before invoking it	2010-01-25 13:37:05 +00:00
adamdunkels	4f3e8d565c	Added a simple CSMA (Carrier Sense Multiple Access) mechanism that ... works on top of an underlying duty cycling mechanism. The CSMA layer retransmits packets that could not be sent because of a collision was detected.	2010-01-25 11:46:44 +00:00
adamdunkels	7ad93e5d18	Added a field to the struct mac interface: ... channel_check_interval(). This function returns the interval by which the duty cycling mechanism checks the radio channel for activity. It is used by higher layer mechanisms to determine suitable timeouts for retransmissions.	2010-01-25 11:43:32 +00:00
fros4943	26e0bab11a	bugfix: alignment problem caused by previous bugfix	2010-01-21 11:39:35 +00:00

adamdunkels	5aab2eb77d	A simple addition with significant performance implications: ... sicslowpan tags TCP packets with the PACKETBUF_ATTR_PACKET_TYPE_STREAM flag, which makes the underlying power-saving MAC layer keep the radio on for some time after transmitting the packet. This allows reply packets to be processed directly, significantly increasing TCP latency and throughput.	2009-11-02 11:58:56 +00:00

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. Additionally, the ACK optimization was improved so that data/ack exchanges now are more efficient.	2009-10-18 13:19:25 +00:00

adamdunkels	fe30886b37	Added functionality for decaying routes: when a packet is sent over a route, it is decayed.

It turned out that ... since libc rand() returns a signed int, there were frequently problems with timer values wrapping. By reverting to random_rand(), we can provide a random generator that returns an unsigned and the timer problems are solved.	2009-02-11 11:08:53 +00:00
adamdunkels	9d75781a78	Added packet attributes for energy spent on a packet (RIMEBUF_ATTR_LISTEN_ENERGY and RIMEBUF_ATTR_TRANSMIT_ENERGY)	2009-02-10 23:51:12 +00:00
adamdunkels	b15198b9a8	Bugfix: the Chameleon header parser modules should not clear the packet attributes, because the MAC or radio layers may have added attributes already	2009-02-10 23:49:58 +00:00
adamdunkels	e1ef13dad6	Reduced the size of the packet cache from four to two to avoid falseley dismissing fresh packets (the header field that hold sequence numbers is only two bits wide, hence all sequence numbers fits in a four-entry cache...)	2009-02-10 00:44:50 +00:00
adamdunkels	6c95bd895a	Added default initialization of polite announcements. Not sure where the best place for this is, but this at least allow us to start experimenting with this.	2009-02-09 22:05:33 +00:00
adamdunkels	3efb83c338	Added announcement includes	2009-02-09 21:09:42 +00:00
adamdunkels	0de445e035	Initialize the announcement module	2009-02-09 21:08:12 +00:00
adamdunkels	3670ef2f44	Rewrote the collect module so that it uses the announcement module rather than the neighbor-discovery module. This makes it possible to implement other annoumcement back-ends than the traditional broadcast-based neighbor discovery	2009-02-09 20:58:25 +00:00
adamdunkels	dd9ffd87c4	Added missing #include announcement.h	2009-02-08 20:14:18 +00:00
adamdunkels	085df6b630	Improved version of LPP with support for broadcasts as well as announcement data in the probes	2009-02-08 19:30:18 +00:00
adamdunkels	91d280c4c9	Reverted to the old behaviour on broadcasts: send strobes for both unicast and broadcast packets.	2009-02-07 18:45:50 +00:00
adamdunkels	4b71003c2f	Changed from random_rand() to rand() for better pseudo randomness	2009-02-07 18:43:45 +00:00
adamdunkels	752291f450	Changed from random_rand() to rand() function for (pseudo) random numbers because random_rand() does not work that well	2009-02-07 16:16:31 +00:00
adamdunkels	91e8487032	Added Doxygen documentation	2009-02-07 16:15:37 +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
fros4943	4f1a9d3c75	bugfix: stopping timeout timer when we receive route reply (still limited to only one active discovery)	2009-01-21 14:29:24 +00:00
adamdunkels	71e5adb254	Moved packet attributes specifications from rimebuf.h to the appropriate protocol header files	2009-01-15 22:15:51 +00:00
c_oflynn	5ec6412fbc	*Support for Atmel 'Router Under Mac' (RUM) in Jackdaw	2008-12-10 21:26:05 +00:00
c_oflynn	17790ce46a	Bug fix by David Kopf - sicslowpan timeout was always set at 20 seconds, this greatly improves performance!!	2008-12-02 22:04:16 +00:00
adamdunkels	50b1e60621	Rewrote the rimeaddr_copy() loop to use the ->u8 field instead of the ->u16 field (which now finally is removed)	2008-11-30 18:26:57 +00:00
adamdunkels	6951d9d582	Removed the unused ->u16 field (it was there only as a convenience/laziness access method during the initial development of the Rime stack, but has caused problems when being there)	2008-11-30 18:26:06 +00:00
oliverschmidt	7cf3165155	Replaced NETSIM macro with general (and now actually working) solution in Makefile.include.	2008-11-17 22:52:10 +00:00
fros4943	e42d572f81	updated for latest mac driver structure	2008-11-12 12:42:41 +00:00
zhitao	229d60d691	Neighbor ETX should accumulate over retransmission timeouts; ... Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.	2008-11-12 10:47:17 +00:00
oliverschmidt	75ffd0640c	Inform user about (most likely unintentional) call of dummy_tcpip_output_function.	2008-11-10 21:00:53 +00:00
adamdunkels	3b283a5ff3	Added dummy function so that tcpip_output() always is defined, even if tcpip_set_outputfunc() never has been called. This fixes a bug with programs attempting to use the network when compiled for the native platform.	2008-11-09 12:29:24 +00:00
adamdunkels	5243d58ac5	Added logic for announcing that a network has a gateway to the outside world (with the function uip_over_mesh_make_announced_gateway()). The announced gateway sends a trickle message to the network, containing the address of the gateway. Other nodes will then know that packets destined to the outside world should go through the gateway node.	2008-11-09 12:20:56 +00:00
adamdunkels	8851a6359a	Remove unguarded printf()	2008-11-09 12:16:05 +00:00
oliverschmidt	28889f2210	Commented out otherwise unguarded printf().	2008-11-06 23:15:58 +00:00
nvt-se	0c4f7bed8f	temporary fix to get sicslowpan.c working on the Sky platform: ... conventional MAC implementations require a call to the MAC driver's read function.	2008-11-06 20:45:06 +00:00
adamdunkels	d73124cc5e	Bugfix: there was a problem with TCP segments not being properly retransmitted for protosockets-based applications. Cleaning up the logic around acknowledgements and retransmissions fixed the bugs pertaining to retransmissions of lost packets. This bugfix affects both the telnet server and the web server (which now work as expected wrt packet loss).	2008-10-31 18:10:24 +00:00
adamdunkels	f623b81d59	Temporarily out-commented the problematic code and added a comment that describes the problem	2008-10-17 14:40:16 +00:00
mdurvy	75f036f698	uncommented the remove of the router (necessary for compliance)	2008-10-16 09:07:43 +00:00
blakelev	99f6932cdf	Removed one line to prevent the default router from being removed ... prematurely. This timer should not time out, but it does.	2008-10-15 23:29:38 +00:00
