Zigbee路由改进算法研究

ZigBee protocol standard is still developing, so improving the ZigBee routing algorithm is an important element of the ZigBee protocol updates. Based on the analysis of existing improvement of ZigBee routing algorithm, the paper makes an improvement by comprehensive using of Cluster-Tree algorithm and the "piggyback" technology to increase effective load capacity of the network, and then testing its feasibility by simulating in NS-2.Simulation results show that the improved algorithm reduces the number for routing control packets without affecting the other properties, so that the effective load capacity has been improved.
