Scalability Study of ZigBee Mesh Routing Protocol
Jianwu Zhang · Journal of Hangzhou Dianzi University · 2008
The routing algorithm of ZigBee mesh networks is ad hoc on-demand distance vector(AODV),which is used in MANET.AODV based on flooding for discovering any route,so the network performance decreases sharply as more nodes join a network,and limit the scalability of network.In this paper,we propose a mesh routing protocol that helps to enhance scalability for ZigBee mesh networks,which is called ZiCL(ZigBee Cluster Label).ZiCL uses hierarchical address structure of ZigBee to divide a network into some clusters,and then assigns a unique cluster label to each cluster.ZiCL performs routs discovery for destination based on Cluster Label.This results in fewer router discoveries.Simulation results show that ZiCL helps to reduce routing overhead and improve scalability of ZigBee mesh networks.
