A Routing Algorithm of ZigBee Network Based on Weighted Link and Node States

The ZigBee wireless sensor network is an important supporting technology of IoT (Internet of Things). For the reason that various applications of IoT may incur heavy traffic on the network of ZigBee, and the existing methods of constructing ZigBee topology routing tree fail to consider both the link configuration and the busy-degree of the node, so the existing routing algorithm should be optimized to advance the performance of the whole network. Aiming at the above shortcomings, this paper takes the busy-degree of the node, link quality and number of hops into account, and proposes a compositive weighted routing (CWR) algorithm. Experimental results on NS2 show us that the algorithm can improve the packet average arriving rate, decrease the packet average end-to-end delay and keep energy balance among nodes.
