Topology Control Algorithm of Wireless Sensor Network Based on Energy Equilibrium

Topology control technology has important effect on the performance of wireless sensor network. Based on local minimum spanning tree algorithm, this paper proposes topology control algorithm based on energy equilibrium. The algorithm synthetically consider the communication energy consumption between nodes and the node´s residual energy, which can not only make the local total energy consumption close to minimize, and can also make node´s energy balance. The simulation results show that our algorithm can ensure lower end-to-end delay, higher throughput and delivery rate and so on, and effectively prolong the network life time.
