ABSTRACT
The fault local route repair mechanism of AODVjr is after the link is broken in Zigbee network, the lagging repair process causes the cache data packet loss and the data end-to-end delay. In this paper, a Zigbee link availability prediction algorithm (APR-AODVjr) is proposed to predict the link availability of the AODVjr routing algorithm, which starts the route discovery process before the link breaks. Simulation results show that the routing algorithm based on link availability prediction can effectively reduce the network fault recovery response time, prolong the network lifetime and reduce the network congestion and delay.
