| 摘 要： | 在能量有效加权分簇(EWC)算法的基础上,提出一种簇首选择算法EWC-N(new EWC)。该算法根据节点的邻节点数量与剩余能量计算出权值,选出权值大的节点为簇首,在选择簇首的过程中,动态调整簇首之间的距离。该算法减少了分簇过程中能量的消耗,簇首的分布更加合理。仿真实验结果表明,该算法相对于EWC提高了能量有效利用率近9%,延长了约12%的网络生存时间。

| Abstract: | Based on the energy efficient,weight-clustering(EWC) algorithm,a novel algorithm called EWC-N(New EWC) is proposed.After calculating weight according to its neighbors and residual energy,the EWC-N algorithm selects the cluster-head whose weight is biggest among the neighbor nodes and dynamically adjust the distances among the cluster-heads in cluster-head selection pro-cess.The algorithm decreases the energy consumption rate in the process of clustering and makes the distributions of cluster-heads more reas... |
