Adam Dunkels 5f3fe7f7c7 Updated include paths for the moved files under net/ 2014-01-26 23:20:23 +01:00

Adam Dunkels faff1c2a7e Preliminary support for RPL node types. This change allows a node to be in any of three given types: 
* Mesh: this is the normal case. Nodes route data on behalf of others and the node can be reached via a DAO route.
* Leaf: the node does not route data on behalf of others, but others can route data to the node (it has a RPL DAO route).
* Feather: this is a new type of node. A feather node routes data on behalf of others, but does not install DAO routes in the network. Feather nodes allow having a larger number of nodes than the RPL network can sustain in terms of routing tables.

This commit introduces the RPL node types and the feather mode, but does not add support for the leaf node type.

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 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.

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

Mariano Alvira bb1baffc79 change FIX2ETX -> NEIGHBOR_INFO_FIX2ETX in some debug prints. 2011-02-17 20:54:57 -05:00
Nicolas Tsiftes 93a7280a1a Replaced old description 2011-02-15 18:10:15 +01:00
nvt 99d0387a8e Merge branch 'master' of github.com:adamdunkels/contiki-2.x 2011-02-15 01:13:41 +01:00
nvt a093c262ee Improved objective function API so DAG metric containers can be generated cleanly. The packet generation now asks the OF to provide a fresh logical presentation of the metric container, which is then translated to raw packet format. 2011-02-15 01:13:30 +01:00
Adam Dunkels db37e38156 Make sure we don't remove the preferred parent 2011-02-14 23:01:11 +01:00
nvt cbe4513bf4 basic support for parsing metric containers in DIOs 2011-02-13 23:17:56 +01:00
nvt 539ff33104 Turn off debugging 2011-02-13 21:36:07 +01:00
nvt 5ec2f19dc9 Remove only the worst parent if the table is full when processing a DIO. 2011-02-13 21:33:47 +01:00
Adam Dunkels 432928d000 Changed the name of macros defined in neighbor-info.h to have the NEIGHBOR_INFO prefix. 2011-02-13 21:29:59 +01:00
Adam Dunkels acb5480aa9 Changed the name of macros defined in neighbor-info.h to have the NEIGHBOR_INFO prefix. 2011-02-13 21:21:14 +01:00
Adam Dunkels 15bf73ba08 Use DAG_RANK() macro to compute rank 2011-02-13 19:01:15 +01:00
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
Joakim Eriksson d24c63c0f1 fixed so that minhoprankinc is configurable 2011-02-10 19:44:12 +01:00
