Ivan Delamer 02d3fd4758 Fixes small bug in uip-nd6.c: when a packet is sent before DAD is 
completed, DAD-like message is sent that can create a DAD fail in
another node (if it matches the destination of our packet).

Niko Pollner 84105f4e47 Improved multihop/mesh route discovery. 
Packetbuffer is now saved before route discovery and resent when a
route is found.

This solves the following problems:
- First packet sent to a certain node is corrupted.
- Packet to be forwarded that triggers route discovery is lost.

Adam Dunkels 2da65385a0 Added a SICSLOWPAN_CONF_COMPRESSION_THRESHOLD that can be used to set a threshold under which header compression should not be used. Below this threshold, headers are not compressed but sent as full IPv6 packets. This is useful for RDC layers, such as ContikiMAC, which set a lower bound for packet size. 2011-09-02 13:51:09 +02:00

The old parent selection would always favour parents with a lower rank, regardless of their ETX, which in some cases lead to suboptimal parent selections.

adamdunkels 09c223f549 Updated Contiki X-MAC to use hardware acks, which allows for tighter timing and results in a lower duty cycle. Hardware acks also make X-MAC more robust against packet losses, as there is a direct way for the CSMA layer to detect loss of data packets. Before, Contiki X-MAC only detected loss of strobes. 2011-01-25 14:31:09 +00:00

adamdunkels 4914739e5d Revived the timesynch module, which has been switched off since the introduction of the new radio API after Contiki 2.4. The new code uses explicit timestamp messages instead of piggybacking timestamps on every transmission. It is also significantly better in terms of exactness. 2010-12-16 22:47:38 +00:00
adamdunkels 10fb99a89d Reduced the value of the max depth, so that a count-to-infinity loop will not count too long before hitting the maximum value. This is important when a network loses its sink, so that packets are not forwarded around the network for ever. 2010-12-16 22:46:34 +00:00
adamdunkels 19e930e6f2 Changed the behaviour of retransmissions to work better with the in-order CSMA code. The retransmission timer is now set when the packet is known to be sent by the MAC layer. 2010-12-16 22:45:15 +00:00

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

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.

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 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.

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 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

count.

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 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

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.

* 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.

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.

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 5cf3b83733 Common initialization code for the netstack 2010-02-18 23:15:26 +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 2fbf21b2b3 Refactored the phase optimization functionality into a separate module 2010-02-18 20:58:59 +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 b98f7d891f Bugfix: added missing queuebuf allocation 2010-02-06 20:50:24 +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 4bffd277f5 Don't set the stream bit on outgoing TCP packets for now - it doesn't seem to play well with IPv6 and X-MAC 2010-02-03 16:44:19 +00:00
adamdunkels 36db5eb70b Added debug printout 2010-02-03 01:18:24 +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 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.

adamdunkels cc3f609eaa Bugfix for alignment issue. Added mechanism that allows five duplicate announcements before suppressing one's own. 2010-01-25 13:55:17 +00:00
adamdunkels 71ffde578e Moved route_init() into mesh instead of the generic rime initialiation 2010-01-25 13:54:26 +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.

properly timed.
 2009-12-06 13:18:32 +00:00
adamdunkels 822149f943 Significant improvements to the Contiki X-MAC: 
* the code is simplified, particularly the duty cycling logic
* old unused code has been removed
* Contiki X-MAC now listens before sending a strobe to avoid MAC-level
  collisions
* broadcasts are sent directly, without strobes, reducing the power
  consumption of receivers
* turn off radio for 1 ms between sending a strobe and expecting the
  strobe ack

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.

adamdunkels 4de1816e36 Added a new module called "framer" that creates MAC level frames to 
the packetbuf from packet attributes. Two framer modules are included,
one that creates 802.15.4 frame headers, and one that creates a
minimal "nullmac"-style header that only contains the link-local
addresses.

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.

adamdunkels 02734c9806 Bugfix: must copy the sender and receiver addresses from the packetbuf buffer, otherwise an application program may overwrite them 2009-05-10 21:10:02 +00:00
adamdunkels fe5a1f1068 Added an optimization option that avoids multiple simultaneous broadcasts from neighbors: when a broadcast is to be sent, a sender does not send until it knows that no other nodes are broadcasting. 2009-05-10 21:09:05 +00:00
adamdunkels fe30886b37 Added functionality for decaying routes: when a packet is sent over a route, it is decayed. If the route is not refreshed within four packets (with the route_refresh() function, which is called when a new packet arrives), the route is dropped. A route can be decayed at most once per second 2009-05-10 21:08:01 +00:00
adamdunkels 6bf8e0b478 Bugfix by Takahide Matsutsuka: too few items in array, which caused problems with sdcc 2009-05-08 08:52:55 +00:00

adamdunkels 1752b53f74 Refresh routes when a packet is received. Set a conservatively low route timeout (10 seconds). 2009-05-04 11:24:04 +00:00
adamdunkels c83c5c4c55 Removed automatic refresh of routes from the route_lookup() function and moved it into an explicit route_refresh() function. The previous behaviour was dangerous, since it meant that even bad routes that someone was looking for were considered fresh. Now such routes time out if they are not explictily refreshed (e.g., on a packet reception) 2009-05-04 11:23:30 +00:00
adamdunkels f5a57a4e54 Fixes by Ward Van Heddeghem (reapplied from versioin 1.24) 2009-04-30 20:21:06 +00:00
adamdunkels e70cf0c7c6 Rewrite of the collect module. The new version uses a packet queue for outgoing and forwarded packets so that more than one packet can be forwarded at the same time. The new version uses the packetqueue module to maintain the packet queue. 2009-04-29 20:48:57 +00:00
adamdunkels c489b1118d New module: packetqueue. The packetqueue module maintains packet queues for other modules. 2009-04-29 20:47:30 +00:00

adamdunkels aaa8c9d2c9 Construct the X-MAC header on the stack instead of directly in the packet header, because the packet header may be misaligned. A bit of cleanup in the code too. 2009-02-15 22:05:06 +00:00
adamdunkels e4b1ff461e Added MAC-layer announcement beacons to X-MAC. Configuratble through XMAC_CONF_ANNOUNCEMENTS 2009-02-14 20:35:03 +00:00
adamdunkels 585620c102 Reverted the recent change from random_rand() to rand(). It turned out that 
since libc rand() returns a signed int, there were frequently problems with

random generator that returns an unsigned and the timer problems are solved.
 2009-02-11 11:08:53 +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.

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

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.

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

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

blakelev 99f6932cdf Removed one line to prevent the default router from being removed 
prematurely.  This timer should not time out, but it does.

adamdunkels 31509ad726 Fixed a bunch of bugs in the collection neighbor announcement/discovery code: neighbor announcments were not repeated unless there was a change in the ETX val. Neighbor announcements happened to often when there were changes in the ETX. 2008-08-15 19:00:38 +00:00
adamdunkels 210782d9c6 Set the channel as a packet attribute 2008-08-15 18:59:22 +00:00
adamdunkels 9a4e5dfabf Rewrote the neighbor discovery code so that messages are suppressed if a lower rtmetric is received. This reduces the overall number of broadcast packets. 2008-07-09 09:33:58 +00:00
adamdunkels 9318117429 Fixed function prototype compiler warning 2008-07-08 10:59:31 +00:00
adamdunkels ba5c18a468 Rewrote the trickle code to run directly over the broadcast primitive: the previous implementation did not work as expected, because packets were not supressed correctly by the previous underlying netflood primitive 2008-07-07 23:29:30 +00:00
adamdunkels df33cb6e16 Only send ACK if it was possible to allocate a queuebuf to hold the data packet. 2008-07-07 23:27:57 +00:00

nifi fabe4393f7 fixed alignment problem with rime/chameleon 2008-04-01 13:10:22 +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. ***

adamdunkels a0c833da11 Mistakenly included development code in the Makefile target 2008-02-25 13:22:34 +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:

Architecture for Wireless Sensor Networks. In Proceedings of the Fifth
ACM Conference on Networked Embedded Sensor Systems (SenSys 2007),

This is a rewrite of the code that was developed for the paper.
 2008-02-25 02:14:34 +00:00
adamdunkels 974870359a Changed all occurences of u8_t and u16_t to uint8_t and uint16_t 2008-02-24 22:10:30 +00:00
adamdunkels d99ca27820 Changed all occurences of u8_t and u16_t to uint8_t and uint16_t 2008-02-24 22:05:27 +00:00

adamdunkels be1dd57cb3 Stopping watchdog before sending packets to allow for wait times longer than 1 second. Reduced default on time to 5 ms. Added option for turning off X-MAC but keeping the radio turned on. 2008-02-24 21:07:28 +00:00
adamdunkels 32a3fa5d4a Added parameter to the mac off() method that specifies whether or not the radio should be turned off when the MAC layer is turned off 2008-02-24 21:05:28 +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 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 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 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

 2007-05-21 14:30:38 +00:00
oliverschmidt 5f3296e943 Changed packet drivers from services to plain processes. 
Now tcpip_output() is a function pointer that is supposed to be set via the macro tcpip_set_outputfunc(). Packet drivers do so on process startup.

Thus if there are several packet drivers in a Contiki system the one started last is the one actually used. This behaviour is especially useful for the 'IP forwarding' "meta" packet driver.

bg- 82aa4b4926 * When looking up potentially bad routes use uaodv_rt_lookup_any 
rather than uaodv_rt_lookup.
 2007-05-09 16:45:03 +00:00
bg- faf94db265 * Respect "destination only" flag in RREQs. 
* If our routes seqno is <= requester last known seqno our route must
  be bad (in his eyes). Previos comparison was < which must be wrong.
 2007-05-09 14:53:54 +00:00
bg- 34490eeecb * Make it explicit that some seqno:s are in host byte order by naming 
them hseqno.

* Change uaodv_rt_add to take argument in (standard) network byte
  order (and change it to be a pointer).
 2007-05-09 13:54:41 +00:00

bg- c23e583129 * Added flag UAODV_RERR_UNKNOWN to deal with unknown errors that are 
often the result of rebooting nodes.

* Change function uaodv_bad_route to uaodv_bad_dest.
 2007-05-08 13:33:57 +00:00
bg- 9e9cadabaf * Added flag UAODV_RERR_UNKNOWN to deal with unknown errors that are 
often the result of rebooting nodes.
 2007-05-08 13:32:55 +00:00
bg- a207770a1e * Add attribute to track bad routes and necessary support for this. 
* Revamp forwarding to deal with bad routes or request new routes as
  appropriate.

* Mark bad routes (rather than tossing them) as we are informed by
  other hosts.

* No longer wait two ticks before making route request.
 2007-05-08 08:41:26 +00:00
bg- 67e23ee564 * Add attribute to track bad routes and necessary support for this. 2007-05-08 08:30:49 +00:00
bg- 7ec3d191a2 * Need to track if we at the moment are doing forwarding or sending. 2007-05-08 08:28:59 +00:00
bg- b9a3721076 * Keep track of last known seqno. Send last known seqno in RREQs. 
* If we have rebooted, bump seqno (gleaned from RREQs).

* Reworked filtering of RREQs.

* Use last known seqno check before responding to RREQ that we have a
  route for. Never graft onto an existing but old route.
 2007-05-07 11:51:20 +00:00
bg- 948a88d9e6 * Set route timeout to maximum value for std compliance. 
* Rename aodvconn to bcastconn for clarity and uniformity.

* Use uip_udp_packet_send where possible.

* Change a lot of debug printfs.

* Moved call to fwc_add.

* Set ttl to sensible value if AODV_COMPLIANCE.
 2007-04-30 15:26:09 +00:00
bg- b2bc97ddba * Constness, voidness. 2007-04-30 15:19:21 +00:00

bg- 9acf8e021e * Missing return when filtering out bad neigbours. 
* Make routing messages bypass routing rather than creating artificial
  neigbours.
 2007-04-30 09:49:32 +00:00
bg- a9d536e50c * AODV requires that 255.255.255.255 is not rebroadcasted! Deal with 
this using conditional compilation (AODV_COMPLIANCE).
 2007-04-24 16:58:58 +00:00
bg- 8b1cd7a470 * Explain that SCMP32 comes from RFC 3561 and is easy to implement 
using 2's complement arithmetic. Unfortunately C only defines
  unsigned arithmetic and consequently machines that don't use 2's
  complement (i.e unknown arithmetic) will have to be dealt with on a
  per machine basis.
 2007-04-24 16:37:45 +00:00
bg- 42fe071745 * Some more debug printfs. 
* Correct hop_count when an existing route is found.
