adamdunkels	2cae71e89b	Added a function for obtaining the link estimate and rtmetric for a neighbor	2010-09-22 22:04:55 +00:00
adamdunkels	591766e663	Significant improvements to the Collect protocol: ... * Loop detection and untangling. Now uses in-band loop detection that works. * Link quality estimation. Now starts with a conservative / pessimistic estimate for new links. * Retransmissions. MAC layer and network layer retransmissions are now decoupled. * Loss handling. Deals better with losses now. * Concurrent applications. Each connection now maintains its own neighbor table with separated cost to sink estimates for each connection.	2010-09-13 13:28:14 +00:00
adamdunkels	4e0744954a	Rewrite of important parts of the Collect logic: link estimation ... calculation and parent selection. This fixes a severe bug that caused loops when packets were erroneously retransmitted due to ACK loss.	2010-09-08 19:21:45 +00:00
adamdunkels	7647cbd8aa	Use the list_item_next() API	2010-06-15 19:22:25 +00:00

adamdunkels	7b0606cd58	Renamed the neighbor module to collect-neighbor, as it is only used by the collect module and is not a generic neighbor module	2010-03-19 13:17:00 +00:00
