摘要
通过综合考虑节点分布和剩余能量水平,并对簇的形成过程进行优化,引入机制保证簇的能量消耗均衡,以改进网络生存时间和覆盖率.所提出的分布式分簇算法经过仿真结果表明,新算法相对于现有的多种算法在能量均衡性和网络生存时间上有较大改进,半数节点生存时间延长一倍以上,而负载均衡性仍保持在相同水平上.
The paper proposes a new clustering algorithm. To improve network lifetime and coverage rate, the algorithm takes account of both the distribution and remaining energy level of the nodes and introduces a mechanism to guarantee balanced energy-consumption. The simulation results show that the new algorithm effectively prolongs the network lifetime. The half node alive time of the network is twice longer than that of other algorithms, and load balance factor remains on the same level.
