AODVjr routing protocol with multiple feedback policy for ZigBee network

AODVjr (AODV junior) is a simplified specification of AODV (ad hoc on-demand distance vector) routing protocol and suitable for ZigBee network. To enhance its routing strategy in a ZigBee network, in this paper, we proposed an AODVjr routing protocol with multiple feedback policy by means of processing main message during route discovery. The source node starts the route discovery, the destination node processes every Route Request (RREQ) and sends every route reply (RREP) as feedback information to the source node, and the source node processes multiple RREP messages for routing decision. The improved AODVjr changes the routing decision commander from destination to source and make a proactive routing decision on the basis of multiple feedback information. Through practical sensor platform, the improved AODVjr routing protocol demonstrates a better routing flexibility compared to original routing protocol so that high level routing strategy such as load balance can be implemented. We can verify that the AODVjr routing protocol with multiple feedback policy has larger flexible application in ZigBee-centered consumer electronics.
