ZigBee Tree Routing Optimize Based on Energy-balanced

Aiming at the problem of ZigBee tree routing algorithm in which the solution may not be optimal and some nodes may exhaust the energy as a result of heavy transmissions, an optimized ZigBee tree routing algorithm based on the energy-balance. The optimized algorithm imports neighbor-table and the depth of nodes to make sure the routing local optimal in routing hops. This paper also considers the residual energy of nodes to avoid selecting nodes with low residual energy in routing selection. The simulation result indicates that this improved algorithm can reduce the energy consumption efficiently, maximize the lifetime of the whole network.
