Research on the algorithm of Load-balanced Hierarchical Topology Control for WSN

Abstract

In terms of the characteristics of itself node number, density and topology dynamic change in wireless sensor network, according to the wireless transmission energy consumption model REDM, Load-balanced Hierarchical Topology Control Algorithm based on LEACH algorithm is designed. The algorithm still uses the concept of round. Substitute cluster head and load evaluation method are introduced in view of frequent election of cluster head after cluster head failure. It can reduce cluster formation frequency, balance network energy consumption, extend the network lifetime and improve network management efficiency. Finally, the simulation results have verified this conclusion.
