Self-adaptive and fast route recovery algorithm for WPAN mesh networks.

The server routing (SR) algorithm has problems of large network overhead and long time route recovery in the route recovery stage of SR. To address this issue, a self-adaptive and fast route recovery algorithm (SFRR) is proposed. In SFRR, two new mechanisms which piggyback the source information and choose adaptively the route recovery mechanism are introduced to reduce the network overhead and improve the speed of the route recovery. Theoretical analysis and simulation results show that the network overhead, the average time of route recovery and the average end-to-end delay of SFRR are outperform that of SR.
