基于剩余能量和覆盖率感知的分簇协议
Clustering protocol based on residual energy and coverage aware routing
摘要
Abstract
The most fundamental target of the wireless sensor network(WSN)application is to preserve the coverage of the target area. Therefore,the design of the energy efficient algorithm to cover the time to the maximum extent is the central prob⁃lem of the large⁃scale network. The distributed⁃energy and coverage aware routing(DECAR)protocol is proposed to realize the target of maximum network coverage. The CH(cluster head)election is based on the residual energy and coverage overlapping degree of the nodes,so the node with high residual energy and high coverage overlapping degree has more opportunity to be⁃come the CH. The problem of reducing network lifetime is avoided,which is caused by the node premature failure when the node with less residual energy becomes the CH. The network energy consumption is balanced. In data transmission stage,the data transmission backbone composed of the CHs was constructed to improve the data transmission rate. The simulation results show that the proposed DECAR protocol has longer network lifetime and wider coverage rate than those of the CPCP⁃ea and EEUC pro⁃tocols.关键词
