【摘要】 提出了一种基于能量效率的WSN多跳簇生成方法(MEET)。根据节点剩余能量,簇内平均可达功率和节点到基站的平均距离竞争原则选择簇首,并采用最小通信代价的多跳分簇结构。通过仿真结果表明,MEET形成的簇首分布较为均匀,可利用最佳多跳路径节约传输能量,提高网络生存期,与LEACH相比有较大优势。更多还原

【Abstract】 A multi-hop energy-efficient topology(MEET) algorithm is proposed,which selects cluster heads according to the priority of residual energy,average minimum reachability power and distance from nodes to basestation,and adopts the minimum inner-cluster communication cost structure.Simulation results show that the cluster heads are evenly distributed,and energy is saved to improve the network lifetime by MEET algorithm.Its performance is superior to LEACH.更多还原
