Research on Tree Routing Improvement Algorithm in ZigBee Network

Based on deeply studying the tree routing in ZigBee, the improvement tree routing algorithm (NTR) by using the neighbor table had been proposed in this paper: finding the common neighbor nodes between the source nodes and destination nodes; establishing a strategy on selecting neighbor nodes. The NTR can enable the original tree routing more flexible, save the address space and improve the routing efficiency. The results had shown that the NTR could reduce the network costs and end to end delays, leading to the energy conservation and the real time of the network enhancement.
