ZigBee Hybrid Routing Optimization Algorithm Based on Energy Balance

Aiming at energy consumption problem in the ZBR hybrid routing algorithm, an improved algorithm (W-ZBR) based on ZBR routing protocol is proposed to reduce the network energy consumption. The algorithm was improved mainly from the following parts: Cluster-tree routing algorithm and AODVjr routing algorithm. In Cluster-tree routing algorithm the redundant packet of RREQ is limited to reduce energy consumption by setting the parent node id. In AODVjr routing algorithm the network energy consumption is balanced by monitoring the remaining energy of nodes. The simulation result indicated that W-ZBR performs better than ZBR in remaining energy ratio, routing overhead ratio, available node ratio and packet delivery ratio. The algorithm can also prolong the life span of network.
