Simulation Study on Optimization of ZigBee Routing Protocol Based on Improved Cluster Tree Algorithm

In order to solve the problem of high energy consumption, low routing efficiency, and long network delay in the two main routing algorithm. The paper proposed an improved cluster tree algorithm that combinated the routing algorithms of AODVjr and cluster tree. Based on the basic ZigBee routing algorithm, classified the routing algorithms of AODVjr and cluster tree. basic ZigBee routing algorithm, classified the routing nodes according to the residual energy of the nodes, and simplified the algorithm process, used the characteristics of data transmission as the basis of alternative routing algorithm. The simulation results showed that the improved cluster tree algorithm performance better. The simulation results showed that the improved cluster tree algorithm had better performance. However, the delay of improved cluster tree algorithm would be slightly larger when the number of nodes were same, and it had better performance in energy balance, achieved the purposes of energy optimization, met the requirements of low cost, low energy consumption, high reliability of wireless sensor networks. high reliability of wireless sensor networks.
