An Improved Routing Protocol Based on Cluster Tag in ZigBee Network

Zigbee is based on IEEE802.15.4 standard for Wireless Personal Area Networks. As traditional ZigBee is based on AODV, whose data delivering manner is similar to ad hoc network. Routing overhead for route discovery may interfere with network performance. In the paper, we proposed an improved routing protocol based on Cluster Tag. As ZCT divides the ZigBee network into one or more logical clusters and makes nodes to share routing information, it reduces route discoveries. Simulation results show that ZCT makes network performances such end-to-end delay and packet delivery ratio are significantly improved, especially in dense network.
