Improvement of ZigBee Cluster-Tree Routing Algorithm Based on Energy Saving
In order to realize the energy balance of ZigBee, prolonging the survival time of the network, avoiding the paralysis of the network, this paper improves the tree algorithm. This paper firstly introduces ZigBee and the results of some routing algorithms, and then analyzing and comparing the original tree algorithm and AODVjr algorithm, finding out the inadequacies. The original tree algorithm is improved by routing table, eliminating invalid neighbor nodes and balancing energy. Experiment results of simulation show that: Sending 1000 packets, the improved algorithm is 750 hops less than the original algorithm, and high load nodes 5 less than the original. Therefore, the improved algorithm is effective, it saves the number of hops, that is to save energy.
