Adam Dunkels 61ea7fbb1c RPL DAO timers and management: 
* Added a DAO lifetime timer that sends out a new DAO after half the lifetime of the DAO. This allows implementing DAO route soft state that avoids routing tables in the network keeping stale routes for ever.
* Added ways to schedule a new DAO transmission as well as cancelling an active DAO transmit timer, which makes it possible to do nodes that don't send DAOs.

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

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

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 edf141046b Clean up of a few missing printf() that were converted into PRINTF()s 2012-11-27 23:04:34 +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
Adam Dunkels 2a2175a214 Make RPL DIS transmission interval random in the interval [0, INTERVAL/2]. This is needed to avoid synchronization in large RPL networks. 2012-11-27 23:04:31 +01:00

Adam Dunkels 15deb37e64 Updated DAG version processing to occur even for infinite rank DIOs. This makes it possible for the RPL root to infer the DAG version number from a network that hasn't had a root for a while, and where the rank has increased to infinity. 2012-11-27 23:04:30 +01:00
