Energy Balance Hierarchical Data Aggregation Mechanism for Wireless Sensor Network

Abstract—To balance energy consumption for nodes in wirelesssensor network (WSN) is an important considering factor. Asimple model is set up to analytically evaluate the energyconsumption in WSN by using aggregation mechanism. It isshow that energy consumption of an aggregation nodeincreases so rapidly in the neighborhood of the sink node. Amodified hierarchical data aggregation strategy is proposed inorder to achieve balanced energy depletion by reducing thecluster head selection probability near the sink. Simulationresults show that, this method can reduce the energyconsumption efficiently and prolong the lifetime of the wholenetworks.
