Abstract
Unbalanced energy consumption of sensor nodes in wireless sensor network WSN leads to the formation of hotspots that can shorten network lifetime Based on the study of hybrid energyefficient distributed HEED clustering a cellclustered algorithm for energy efficiency CCHEED is proposed to save the limited network energy in WSN According to the power consumption model the inner cluster regions in this hierarchy network are further divided into several cellshaped areas in which cell nodes are brought out to assemble the data in each cell area In addition comparisons are performed on network lifetime with other traditional routing algorithms to verify the validity of the routing protocol Simulation results show that the proposed CCHEED can significantly reduce energy consumption in WSN and network lifetime is prolonged notably with high energy efficiencyThe authors would like to thank the Natural Science Foundation of Jiangsu Province BK20130977 the Natural science foundation for colleges and universities in Jiangsu Province 13KJB580007 and Graduate Innovation Funding Project of Jiangsu Province KYLX 0867 for partly funding this project
