An Improved Cluster-Tree Routing Algorithm in ZigBee Networks
HE Ling-ling · Chuangan jishu xuebao · 2010
ZigBee, a new kind of wireless sensor network based on the address allocation mechanism, has a strong networking capability, which supports topology changing and node moving. Owing to problems of cluster head node of which energy demand is high and non-optimal routing between nodes in ZigBee Cluster-Tree algorithm, an advanced method for forming the cluster head nodes resulting from node energy and finding the best route resulting from AODVjr algorithm is proposed. At the same time, The simulation results indicate that the new Cluster-Tree algorithm can improve the packet transmission success rate effectively, cut down the death of nodes, reduce the end-to end packet transmission delay, and extend the network value.
