An Improvement of ZigBee Cluster-Tree Routing Protocol
ZigBee is a wireless standard for Wireless Personal Area Networks (WPANs), and it is widely used in industrial, commercial, medical fields where low energy consumption is needed. ZigBee routing protocols should be stable, reliable and low-power. Cluster-Tree routing protocol is a simple and reliable routing protocol used in ZigBee network, and it only takes into account parent-child relationships of nodes, therefore its routing path is single and inefficient. This paper improves Cluster-Tree algorithm by introducing a neighbor table. The improved routing protocol has better performance in less energy consumption and a longer life cycle of entire ZigBee network.
