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.

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.

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 515a391ee4 Removed left-over debug printfs 2010-02-15 23:31:05 +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 2b6a651233 Added missing include, made debug statement more explicit 2010-02-08 21:59:21 +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 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 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 b728c0927c Made number of duplicate announcements configurable 2010-01-26 10:18:55 +00:00
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.

adamdunkels 6897270289 Bugfix to the Contiki LPP encounter timing code: encounters are now 
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
 2009-12-06 13:16:59 +00:00

fros4943 583dd11c55 rime_output() now returns RIME_OK or RIME_ERR depending on the MAC return value. 
this patch may affect Rime sniffers running on top of MAC protocols that do not yet return generic MAC return values
 2009-11-13 09:10:24 +00:00
fros4943 26bb5ecd21 added radio and MAC generic return values to allow applications finding out whether the packet was transmitted 2009-11-13 08:59:22 +00:00

adamdunkels 70fc23ac7e Enable stream mode by default, remove LED debug mode 2009-11-04 16:02:45 +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 c7a91ad4a2 Bugfix: UIP_TCP_BUF -> BUF 2009-10-27 23:09:58 +00:00
adamdunkels 631af06c7c Bugfix: Active TCP connections in uIP are made by first setting up the 
TCP connection state, then poll uIP to send out the first SYN. Until
now, however, the SYN was not sent as part of the poll, but at the
first retransmission. This is now fixed.

adamdunkels 9ec57d61ad Added MAC layer framing support to X-MAC so that packets now are standard 802.15.4 frames 2009-10-19 20:53:56 +00:00
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 fb037e0afb Added function for sending an UDP packet to a specified IP address and port number over an existing UDP connection 2009-10-18 22:02:01 +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.

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 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 cc44e89415 Reduced default strobe time, which seems to work well. Avoid running the interrupt if the power-save feature is turned off (fixes problems with serial data reception on a gateway mote) 2009-04-29 11:42:13 +00:00
adamdunkels c02a82ac41 Tag outgoing TCP packets with the ERELIABLE attribute so that an underlying power-saving MAC protocol can treat them differently, because it knows that an ACK might be arriving soon 2009-04-29 11:40:33 +00:00
adamdunkels c9df0ab123 Bugfix in debug message printout 2009-04-28 14:01:46 +00:00
adamdunkels 81ef83b856 Added option to wait randomly before sending a packet. A few code cleanups. Avoid switching radio off when sending a packet with end-to-end acks, because an ACK may arrive shortly after the transmission. 2009-04-28 14:00:53 +00:00
adamdunkels fdd05f5c71 Bugfix: psock send should use PT_WAIT_UNTIL() not PT_YIELD_UNTIL(). This improves TCP throughput by 100x under minimal-net 2009-04-28 13:52:04 +00:00
fros4943 7810d362a6 minor bugfixes: a rucb sender could not immediately after start receiving a bulk transfer 2009-04-16 14:32:01 +00:00

nvt-se 461ba4082c in case UIP_CONF_ROUTING is set, check if we have a registered routing 
module and use it for looking up the next hop of an address.
 2009-04-06 13:18:12 +00:00
nvt-se faf083f09d save copy of a rime address that points to a packet buffer, since the 
packet buffer is cleared and overwritten before the address usage is done.
 2009-04-06 13:16:39 +00:00
nvt-se c531f25c94 A module that enables Rime to run over UDP. 2009-04-06 13:13:26 +00:00

adamdunkels 8dbd2b2337 Significant power consumption optimization: LPP now keeps track of encounters with neighbors and uses this information to keep the radio switched off longer. 2009-04-03 19:59:22 +00:00
adamdunkels 1d86b01bfb Made optimizations explicit (and configurable). Added missing initialization of dutycycle protothread. Reduced default listen time and off time. 2009-04-03 11:45:06 +00:00
adamdunkels 04101aae36 Fixed alignment problem on the MSP430, where the LPP header may be misaligned 2009-03-31 17:39:54 +00:00

nvt-se 1d47e2a8da send immediate probes only if the packet is directed to us. 
sleep for OFF_TIME if the queue is empty.

restrict double packet lifetime timeouts to unicast packets.

stop ctimer in remove_queued_packet in case the function is not called
via the ctimer callback. it could overwrite a valid packet otherwise.
 2009-03-31 14:11:25 +00:00
nvt-se dd082f7fcf improvements to lpp based on code from Adam and discussions with Thiemo.

adamdunkels fb8fab739a Renamed the rimebuf module to packetbuf to signal that the module is used outside of a pure Rime context (e.g., the sicslowpan code uses it). 2009-03-12 23:04:52 +00:00
adamdunkels 65eb5fd4e8 Renamed the rimebuf module to packetbuf to signal that the module is used outside of a pure Rime context (e.g., the sicslowpan code uses it). 2009-03-12 21:58:20 +00:00

zhitao 0a12098bd5 avoid ping pong packets during route disruption 2009-03-06 17:33:59 +00:00
adamdunkels dc7491f810 Bugfix and optimization: X-MAC did not properly switch the radio off after sending a packet, resulting in increased power consumption. For packets that require an ACK, we can let the radio be on in anticipation of the ACK (controlled with an WITH_ACK_OPTIMIZATION option) 2009-03-05 19:37:52 +00:00

+ added function for checking if runicast is currently transmitting (non-acked) data
 2009-03-03 12:19:46 +00:00
adamdunkels 9816f49fe6 Changed listen and transmit energy attributes so that they are named _TIME rather than _ENERGY, to indicate that they contain the time during which the radio was switched on and not the energy 2009-03-02 22:00:41 +00:00
adamdunkels 78591a003f Minor documentation update 2009-03-02 21:56:16 +00:00

adamdunkels d813d343c5 Cleaned up old left-over code 2009-03-01 20:38:57 +00:00
adamdunkels 7010eb84b8 Added support for communication power accounting. Energy is attributed to idle listening when the radio is switched off. Enegrgy is attributed to an incoming packet when it is received. Energy is attributed to an outgoing packet when it is transmitted. 2009-03-01 20:37:16 +00:00
adamdunkels aa2f7a3399 Made polite announcement times configurable, added missing right-brace 2009-03-01 10:43:57 +00:00

oliverschmidt bc3d9d2e3c Minor rearrangement. 2009-02-28 11:57:46 +00:00
julienabeille f95c5df7d9 The global prefixes processed must be one less than the total amount of prefixes, as the link local one occupies one slot 2009-02-25 08:35:52 +00:00
adamdunkels 2aedc8490d Compile only if timesynch is enabled 2009-02-20 21:23:22 +00:00
adamdunkels e6907a1d8b Include random.h 2009-02-20 21:22:39 +00:00
adamdunkels 4ec5167276 Rewrote the tcpip_output() and tcpip_set_outputfunc() so that the latter is a proper function (which simplifies debugging) and so that tcpip_output() checks if the output callback function is NULL before calling it 2009-02-20 21:21:56 +00:00
julienabeille 10deaa6fc6 Removed CLOCK_SECOND from stimers in uIPv6, stimers are already in seconds 2009-02-20 07:59:35 +00:00
julienabeille 710e5c621c changed timer to stimer for neighbor, prefix, default router, address list 2009-02-19 16:42:41 +00:00
fros4943 97f76126e6 remembering last received packet id to avoid multiple recv callbacks for the same retransmitted packet (but still sending back acks of course) 2009-02-17 12:40:18 +00:00
c_oflynn 8516626703 Fixed documentation error (thanks to David Kopf) 2009-02-17 01:28:28 +00:00
adamdunkels 36bb3ece64 If no neighbor is found, we listen for announcements. Cleaned up debug output. 2009-02-16 01:18:53 +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
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.

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

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
adamdunkels adc57729c3 struct uip_udp_conn should be declared even if UIP_UDP is zero (it does not add any extra code) 2008-10-15 08:56:44 +00:00
adamdunkels e931260603 Added more curly brackets to ensure ANSI C compliance when UIP_TCP is defined; 2008-10-15 08:52:30 +00:00
adamdunkels 6a3565f5b6 Added an #if around the whole code if IPv6 is defined 2008-10-15 08:08:32 +00:00

*** 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),

 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- 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.
