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.

927cc8d895 Added #if UIP_CONF_IPV6 around the IPv6 code in the uIP source tree to allow the C files to be compiled even if IPv6 is not configured. 2013-03-18 09:45:30 +01:00

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

2396f9b8ea Made DIO interval processing a little easier to follow. Explicitly state that the delay is handled as clock timer ticks. 2012-11-27 23:04:31 +01:00

f112fa99d5 Removed the force flag from rpl_reset_dio_timer. Removed an unnecessary DIO timer reset when changing rank but keeping the same preferred parent. 2012-01-04 11:22:11 +01:00

e000b1abf3 A major update to ContikiRPL resulting in a reduced code footprint by
300 bytes, as well as cleaner protocol logic.

* Made parent management uniform.

* Simplified the DIO processing.

* Improved the Objective Function API and its documentation.

* Removed redundant code at various places.

* Improved identifier naming.

* Switched visualization from candidate parents to preferred parents only.

* Made DAO ACK transmissions configurable.

* Improved initial ETX guess by using a cached local confidence value.

* Added a periodical rank recalculation function to reduce
  the maximum stack depth.

* Increased the Trickle redundancy constant to ensure faster
  topological updates.

f135105567 Added support for multiple objective functions.
Extended the objective function API with a callback function that receives link-layer neighbor information.

Throttled DAO transmissions to one per DEFAULT_DAO_LATENCY period.

Added support for an ETX objective function (hysteresis control still lacking though).

Fixed a leak of routes installed by DAOs.

Control that dst_adv_supported is set before sending DAOs.

Improved debugging output.
