Abstract: In wireless sensor networks which are mainly ZigBee Routing Protocol based, energy consumption of node keeps high randomness in which energy consumption condition of each node could not be predicted in advance. This leads node's energy to consume too much, makes routing efficiency be low and results in long time delay of network. Aiming at these problems, this paper introduces ZigBee Routing Algorithm based on energy optimization. During the process of network operation, one energy threshold is set. If minimum residual energy of node is higher than energy threshold, AODVjr Algorithm is utilized to fully give play to its routing function. While if it is lower than energy threshold, Cluster-Tree Algorithm would be applied to reduce energy consumption. Experiment simulation indicates that the improved algorithm effectively saves total energy consumption of network, realizes load balancing and maximizes its survival time.

 

Keywords: ZigBee, Cluster-tree, AODVjr, Energy optimization, Routing algorithm.
