Simon Duquennoy 03dcca15cb Implement a truncated exponential backoff for csma 2013-11-14 15:02:36 +01:00
Moritz 'Morty' Strübe c67c048cac Clean up setting channel and CCA-threshold for CC2420 based motes. 
The CCA-threshold now defaults to -46 which give better simulation
results and typically also better experimental results.
This adjustment is also needed due to commit 0a13f99 in mspsim. As
promised in https://github.com/mspsim/mspsim/pull/18 it broke the
regression tests.

Nicolas Tsiftes 43b5425493 Cleaned up various fragments and fixed a compilation error that occured when switching metric container. 
Fixed a wrapping problem in the ETX EWMA calculation.

Corrected the multiplier of the link metric, and simplified the configuration
so that the user does not need to specify the multiplier.

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 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 b8c0f2de6c cpu/native: Add file-backed simulated EEPROM to native cpu. 
This patch removes a defunct EEPROM implementation from the native
platform and provides a new EEPROM implementation for the native cpu.
The previous implementation appears to be vestigal.

This is useful for testing code which uses the EEPROM without running
the code on the actual hardware.

By default the code will create a new temporary file as the EEPROM
backing, reinitializing each time. If you would like to preserve the
EEPROM contents or specify a specific EEPROM file to use, you can set the
`CONTIKI_EEPROM` environment variable to the name of the EEPROM file you
wish to use instead. If it already exists, its contents will be used.
If it does not already exist, it will be created and initialized by
filling it with `0xFF`---just like a real EEPROM.

A new example is also included, which was used to verify the correctness
of the implementation. It can easily be used to verify the EEPROM
implementations of other targets.
