Adam Dunkels 86e247025a Removed debugging printout that came before a local variable declaration, which seems to have broken sdcc 2013-08-19 17:48:33 +02:00
Adam Dunkels bfd7e5f25b Fixed a few bugs in the route handling code. While bughunting, rewrote parts of the code to make its intention clearer. Also added a bunch of comments to make the logic of the code more evident. 2013-08-19 17:48:32 +02:00
Adam Dunkels 8dc4e46968 Check if the nexthop neighbor for a given route has disappeared. If so, we drop the route too. If we happen to be the RPL root, we also initiate a global repair as the neighbor may moved. 2013-08-19 17:48:32 +02:00

Adam Dunkels e5a6565137 Loop detection via DAO: if we get a DAO from a parent, that parent thinks we are its parent. We poison it and recalulate our parents. 2013-08-19 17:48:32 +02:00
Adam Dunkels 34119b7ef2 Poor man's loop reparation: reset the DIO timer and hope the neighbor learns a better route. 2013-08-19 17:48:32 +02:00
Adam Dunkels d830e9df3f Implement forwarding error handling: if a packet changes direction, we set the FWD_ERR flag. If we see the FWD_ERR flag, we drop the route that we sent it to. If we are the root node, we also initiate a global repair. 2013-08-19 17:48:31 +02:00

Simon Duquennoy c3f62b24c8 Moved ETX management from neighbor-info to rpl-of-etx. Avoids conversions between different fixed point representations, and simplifies neighbor management. Makes more clear how default-ETX and noack-ETX actually affect the rank. Removed neighbor-info and neighbor-attr. 2013-08-19 17:48:30 +02:00
Simon Duquennoy c50d10aa53 Make RPL use neighbor tables. RPL locks the neighbor used as preferred parent. 2013-08-19 17:48:30 +02:00
Simon Duquennoy 09d26f8060 Make uip-ds6-route use neighbor table. Instead of storing a global list of routing entries that contain both the next hop and the destination, we have a separate list of reachable destination for each neighbor in the global table. 2013-08-19 17:48:30 +02:00
Simon Duquennoy ec609b49eb Make DS6 neighbors use neighbor-table, and move all DS6 neighbor management from uip-ds6 to a new uip-ds6-neighbor module. 2013-08-19 17:48:30 +02:00
Simon Duquennoy 5a1d8d8006 Make phase module use neighbor-table. 2013-08-19 17:48:29 +02:00
Simon Duquennoy cfb3bbdad9 Added new neighbor-table module, a centralized place where to store all data about neighbors, indexed by link-layer address. Meant for use in other Contiki modules such as rpl, ds6, ds6-route, phase, neighbor-info. 2013-08-19 17:48:29 +02:00

Adam Dunkels f5307fc01e Bugfix: must set the SICSLOWPAM_MAX_MAC_TRANSMISSIONS attribute after clearing the buffer, otherwise it will not be used for outoing packets. 2013-08-11 14:27:21 +02:00
Adam Dunkels 0aa448f190 6lowpan fragmentation bugfix: the 6lowpan code had an unfortunate 
interaction with the behavior of the rdc layer. If the first packet of a
fragment transmission was lost, the remaining packets would get dropped
on reception. Moreover, the reception code contained a bug that
sometimes would cause fragments to be misidentified as fragments. Taken
together, these problems would result in a pathelogical network
breakdown if too many fragmented packets would occur simultaneously.

Adam Dunkels 512a339c50 Bugfix: DIOs with infinite ranks should not be ignored as they are used by RPL as a signal by nodes that have lost their routes. Instead of ignoring them, we should send out our latest information to let the node with infinite rank find their way into the network again. 2013-07-26 12:38:25 +02:00

Robert Quattlebaum c0a693672c core/net: Added support for "bridge mode". 
"Bridge mode" allows devices to more easily send 802.15.4 packets as if
they were a different device. It also turns off any packet filtering
that may be implemented at layer 2. It works by allowing
`PACKETBUF_ADDR_SENDER` to be set earlier in the stack.

This is useful for implementing 6LoWPAN-ethernet bridges.

Enabled via setting `NETSTACK_CONF_BRIDGE_MODE` to 1. Disabled by
default.

Robert Quattlebaum f145c17039 core/net/resolv: IPv6 and mDNS ("Bonjour") support. Major refactor. 
This patch updates the DNS resolver to support IPv6 and introduces an
improved API for looking up DNS entries. This patch also adds optional
support for mDNS lookups and responses to the DNS resolver.

Here is a quick summary of the changes:

 * Added support for IPv6 lookups.
 * DNS queries now honor record expiration.
 * Added support for mDNS, compatible with "Bonjour".
 * Implemented a new lookup api, `resolv_lookup2()`, which provides
   more information about the state of the record(error, expired,
   looking-up, etc.).

About mDNS/Bonjour Support
--------------------------

This patch adds basic support for mDNS/Bonjour, which allows you to
refer to the name of a device instead of its IP address. This is
incredibly convenient for IPv6 addresses because they tend to be very
long and difficult to remember. It is especially important for
link-local IPv6 addresses, since not all programs support the '%'
notation for indicating a network interface (required on systems with
more than one network interface to disambiguate).

In other words, instead of typing in this:

 * `http://[fe80::58dc:d7ed:a644:628f%en1]/`

You can type this instead:

 * `http://contiki.local/`

Huge improvement, no?

The convenience extends beyond that: this mechanism can be used for
nodes to talk to each other based on their human-readable names instead
of their IPv6 addresses. So instead of a switch on
`aaaa::58dc:d7ed:a644:628f` triggering an actuator on
`aaaa::ed26:19c1:4bd2:f95b`, `light-switch.local` can trigger the
actuator on `living-room-lights.local`.

What you need to do to be able to look up `.local` names on your
workstation depends on a few factors:

 * Your machine needs to be able to send and receive multicast packets
   to and from the LoWPAN. You can do this easily with the Jackdaw
   firmware on an RZUSBStick. If you have a border router, you will need
   it to bridge the mDNS multicast packets across the border.

 * If you are using a Mac, you win. All Apple devices support mDNS
   lookups.

 * If you are using Windows, you can install Apple's Bonjour for Windows
   package. (This may be already installed on your machine if you have
   installed iTunes) After you install this you can easily do `.local`
   lookups.

 * If you are using a Unix machine, you can install Avahi.

The default hostname is set to `contiki.local.`. You can change the
hostname programmatically by calling `resolv_set_hostname()`. You can
change the default hostname by changing `CONTIKI_CONF_DEFAULT_HOSTNAME`.

You may disable mDNS support by setting `RESOLV_CONF_SUPPORTS_MDNS` to
`0`.

---------------------------------

core/net/resolv: `resolv_lookup2()` -> `resolv_lookup()`

Note that this patch should fix several `resolv_lookup()` bugs
that already existed. There were many cases where `resolv_lookup()`
was being called and the IP address ignored, but later code
assumed that the IP address had been fetched... ANYWAY, those

Oliver Schmidt 1eda821a75 Fixed severe bug in PSOCK_READTO (?) 
Either I found and fixed a severe bug in PSOCK_READTO() or I misunderstood something completely. To me PSOCK_READTO() is supposed to return if either the supplied character was read or if the user supplied buffer is exhausted - sor far so good.

However if the latter occurs up to now PSOCK_READTO() was continuing to process characters already read from the network (aka present in the uIP buffer) in order to check if the supplied character was found there and adjust the return value accordingly. But this means that the character processed this way were lost forever for the caller as the next call to PSOCK_READTO() would continue to read past the characters processed this way.

Therefore I removed that character processing altogether. So now if the user supplied buffer is exhausted before the supplied character is found the next call to PSOCK_READTO() starts exactly where previous call left off.

Oliver Schmidt 29391ef9ae Removed uiplib_ip6addrconv() from IPv4 builds. 
While it may very well be beneficial to have explict uiplib_ip4addrconv() and uiplib_ip6addrconv() available for IPv6 builds I'm having a hard time to see the point in uiplib_ip6addrconv() for IPv4 builds.

Unrelated to the above the dispatching of uiplib_ipaddrconv() to either uiplib_ip4addrconv() or uiplib_ip6addrconv() can be accomplished by the C preprocessor only thus avoiding the size/speed overhead of an additional callframe.

Robert Quattlebaum 5afcbf6fff Makefiles: Allow setting UIP_CONF_IPV6=0 to work as expected. 
Setting UIP_CONF_IPV6 to zero from the make build command line is
something that seems like it should ensure that IPv6 is disabled, but in
fact it actually *enables* IPv6. This seems counter intuitive, so this
patch changes the behavior of the makefiles to handle this case
properly.

George Oikonomou 68f59113d6 Fix a route lifetime bug 
There is a bug in the current route purge routine which would
result in a route's lifetime getting decremented more than once
during the same pass. This commit fixes it

The bug is documented here:

Adam Dunkels a9cab81d4e Added macros that allow handling IPv4 addresses even when uIP is configured to be an IPv6 stack 2012-11-27 23:04:33 +01:00
Adam Dunkels afe13b22bc Rewrote the uIP IPv6 route handling code. Instead of being nested deeply inside the uip-ds6.c file, the route management code is now in a separate file, uip-ds6-route.c. This file presents a lib/list.h API for the routes, which makes the route list much easier to use. Additionally, the uip-ds6-route.c file adds a callback API that invokes a callback when routes are added and removed. 2012-11-27 23:04:33 +01:00

NETSTACK_ENCRYPT and NETSTACK_DECRYPT are defined. Those are intended
to be called as functions NETSTACK_ENCRYPT() and NETSTACK_DECRYPT() to
encrypt and decrypt the packetbuf, respectively. If needed, an
initialization function by the name NETSTACK_ENCRYPTION_INIT() can
also be defined.

Adam Dunkels 6ee1f72486 Removed old unused TDMA-based MAC and RDC code 2012-11-20 20:48:34 +01:00
Adam Dunkels ec8c7e9be0 Cleanup of the node-id.h files. The node-id.h file contains 
declarations of functions for setting and getting a node ID number, a
functionality that exists on many platforms. Since this functionality
was not considered part of the Contiki core, each platform defined its
own node-id.h file. This commit attempts to clean this up by
collecting the node-id.h into a core/sys/node-id.h file that replaces
the old node-id.h files from the platform directories.

Adam Dunkels e980072817 Don't add neighbor as a potential parent if its rank is too high. 2011-02-13 18:05:28 +01:00
Adam Dunkels 2a96835c05 Don't remove all parents that have a worse rank than an incoming DIO: we may inadvertently remove our preferred parent. Instead, remove parents with a rank that is worse than our preferred parent. If we are lucky, this will give us enough space for the new parent. 2011-02-13 14:16:15 +01:00
Adam Dunkels f1ac94e415 Slight code complexity reduction 2011-02-13 14:14:49 +01:00
Adam Dunkels 3a824d0ed6 Added a hysteresis when choosing a new parent: don't switch parent unless the ETX is significantly better (1.5 ETX better). 2011-02-13 14:14:16 +01:00
Joakim Eriksson 48fb9dda9e fixed of0 to respect min hop rank increase 2011-02-13 11:25:53 +01:00
nvt 20171985c6 Split the RPL header into a private and a public header. 2011-02-11 16:21:17 +01:00
Adam Dunkels 706045120f Changed the variable name local_confidence to etx to better reflect what it was used for 2011-02-11 14:18:57 +01:00
Adam Dunkels ba6bf7dd6b Rewrote the parent selection to favour parents with a low ETX and a good rank. 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. Also, the old code was buggy in that it would always pick the worst parent (the one with the highest ETX). 2011-02-11 14:17:26 +01:00
Adam Dunkels bb8377dfee Set the end-of-stream flag on the TCP FIN packet 2011-02-10 22:47:45 +01:00
Joakim Eriksson d24c63c0f1 fixed so that minhoprankinc is configurable 2011-02-10 19:44:12 +01:00
Adam Dunkels 8d55a68ebe Added a PACKETBUF_ATTR_STREAM_END packet flag 2011-02-08 22:20:07 +01:00
Adam Dunkels 46348d9013 Added the low-power streaming mode where frequent channel checks are performed when streaming is on. Enabling this will (by setting WITH_STREAMING to 1), however, significantly slow down Cooja/MSPsim simulations. 2011-02-08 21:57:46 +01:00
Joakim Eriksson d518c84471 made rank calculation depend on selected parent when joining DAG 2011-02-08 19:59:50 +01:00
Nicolas Tsiftes aeca16d01f Just update the node rank and let rpl_process_parent_event take care of the rest 2011-02-07 17:29:23 +01:00
Nicolas Tsiftes e3638d2791 Updated to the minrank-hysteresis OF 2011-02-04 15:46:01 +01:00
joxe 389a4f9220 added rpl-all-nodes multicast address to nodes mcast addresses 2011-01-25 22:41:30 +00:00
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 d51e99a3dd Updated streaming mode to use only about 20% radio. Made guard time more conservative due to problem report by Ricklef Wohlers. 2011-01-25 14:29:46 +00:00
adamdunkels fa524fabd7 Bugfix: q->buf was not tested for NULL, as it should be. Fix by Simon Duquennoy. 2011-01-25 14:24:38 +00:00
joxe e79c0ab1ee fixed rpl so that it sends and receives on the rpl-all-nodes multicast address 2011-01-25 09:55:12 +00:00
joxe 3a643fa0c6 added address macros for rpl-all-nodes 2011-01-25 09:54:03 +00:00
adamdunkels 4b4b8fad56 More recent packet entries. Allow 4 queue entries to be dedicated to generated packets. 2011-01-18 16:05:53 +00:00
adamdunkels 808c21fbfa Bugfix: default should be 3 MAC-level retransmissions if collissions or loss occurs 2011-01-18 16:03:57 +00:00
adamdunkels affba785b5 Enabled phase-lock only for channel check rates of 32 Hz or lower 2011-01-18 16:03:19 +00:00
adamdunkels 26e3b6fdc0 Bugfix by Simon Duquennoy: don't transmit packet until previous packet has been sent by the RDC layer. 2011-01-13 19:06:22 +00:00
adamdunkels 81d23a3a36 Minor bugfixes pertaining to queue handling: if a packet was explicitly dropped, the packet would later be acknowledged despite it never being received; added a limit on how many queue entries that can be used for packets that are being forwarded, to allow for originated packets even if the forwarding queue is filled. 2011-01-10 15:10:43 +00:00
adamdunkels 70f9f075a0 Safeguard against NULL arguments 2011-01-10 15:08:52 +00:00
adamdunkels 148bd60fe1 Bugfix: the defensive retransmission timer setting must be made before the packet is transmitted, otherwise the retransmission timer will always be for the defensive retransmit 2011-01-09 23:49:27 +00:00
adamdunkels 50a3e6ea23 Increased the max ETX to allow for longer paths even with the initial conservative ETX estimate; made collect use announcements by default 2011-01-09 23:48:33 +00:00
adamdunkels acf45ec648 Bugfix: memory wasn't freed when a neighbor was dropped from the list. Also increase the max age to 180 minutes to allow for regular beacons to refresh the neighbor before it is dropped. 2011-01-09 21:20:05 +00:00
adamdunkels 90dc0ceebf Replaced default link estimator with an exponential weighted moving average, which reduces memory consumption per neighbor. 2011-01-09 21:14:22 +00:00
adamdunkels 4e91d9303e Added safeguard timer if the MAC layer would fail to call back after transmission. 2011-01-09 21:13:20 +00:00
adamdunkels a0960154ba Cleaned up parts of the code; added comments 2011-01-09 21:07:01 +00:00

nvt-se 8f76c82433 Improved DAO management. 2010-12-17 15:24:25 +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 4a89cc9db3 Rework of the new CSMA in-order code that fixes a number of smalllish bugs in the in-order code. 2010-12-16 22:44:02 +00:00
adamdunkels 79f2c25dae Rework of the phase-lock optimization mechanism. There were several bugs in the existing code, such as the phase-lock would lose synchronization when a packet was lost. 2010-12-16 22:43:07 +00:00
adamdunkels 01c28ab502 Added explicit timestamp packet type, for the revived timesynch support 2010-12-16 22:41:43 +00:00

dak664 a026c94467 Fix compiler warnings 2010-12-14 22:45:22 +00:00
dak664 0a4a0ffb32 Add SICSLOWPAN_CONF_ACK_ALL for hardware autoack testing 2010-12-14 22:18:20 +00:00
dak664 240d478c1f Allow platform to specify COLLECT_CONF_BROADCAST_ANNOUNCEMENT_MAX_TIME 2010-12-14 22:14:33 +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
dak664 0e60c99e80 Add defines to set stateful address prefixes. 2010-12-13 23:27:40 +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
dak664 f34e5ec798 Convert implicit printf to PRINTF 2010-12-04 21:06:04 +00:00

adamdunkels 6d556d5c13 Fixed bug with link-layer ACKs. Refactored the ACK reception code. 2010-11-25 08:44:34 +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.

joxe 9a1f902881 made rank use full resolution when using OF-ETX 2010-10-28 20:39:06 +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
nifi 25ceab07d2 Update annotation when removing preferred parent. 2010-10-27 12:27:57 +00:00
nifi d2a3f1f257 We found that the preferred parent should be reset in the rpl_remove_parent function. 2010-10-27 12:20:35 +00:00
nvt-se d528039f9a Created a separate function for local repair. Added a statistics structure. Improved the control of malformed packets. 2010-10-27 00:46:40 +00:00
nvt-se c2c0505402 Increased alpha to 85 in order to get slower changes in the ETX. Put back the start guess to 3. 2010-10-27 00:45:24 +00:00

adamdunkels a8848517dd UDP checksum is mandatory with IPv6. (Patch by Robert Quattlebaum.) 2010-10-24 22:28:43 +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

joxe e414c8c5a4 added function for retrieving link etx to neighbor 2010-10-22 11:34:24 +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 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.
