In view of the serious packet loss and energy constraint in the movement of ZigBee wireless sensor networks

a hybrid dynamical cluster routing algorithm based on the ClusterTree+AODVjr protocol is designed on the basis of analyzing the cluster algorithm and the ClusterTree+AODVjr algorithm.By adopting the dynamic cluster mechanism

this algorithm enable the moved nodes to respond in time to the topological changes and rapidly reestablish network connection

thus reducing the packet loss and improving the effective packet delivery rate

while reducing the energy consumption by decreasing flood broadcast of RREQ packet.Simulation results by using network simulator NS2 show that compared with the original ClusterTree+AODVjr algorithm

this improved one can reduce energy consumption by 14% in average and increase average packet delivery rate by 8%.
