| Popis: | 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 energy-efficient distributed (HEED) clustering, a cell-clustered algorithm for energy efficiency (CC-HEED) 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 cell-shaped 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 CC-HEED can significantly reduce energy consumption in WSN, and network lifetime is prolonged notably with high energy efficiency. |
