| 摘 要： | 在无线传感器网络的分簇路由协议中,低功耗自适应分簇(Low Energy Adaptive Clustering Hierarchy)算法是其中比较流行的协议之一.文章根据Leach协议提出了一种新型的簇头选举算法LEACH-NOC(New Optimal Cluster),其簇头选举采用两个步骤,首先通过LEACH分簇的思想,将网络分成若干个簇,然后在簇内重新选择簇首时使其尽量靠近簇的质心且能量大于该簇内剩余节点的平均值.MATLAB仿真结果显示,改进的协议能够具有更好的能量有效性,延长了第一个节点簇头死亡(FND)的时间.

| Abstract: | Low Energy Adaptive Clustering Hierarchy (LEACH) is one of the popular hierarchical routing protocols for Wireless Sensor Network.Aiming at the defects of the Low Energy Adaptive Clustering Hierarchy (LEACH),this paper proposes a novel routing protocol-Low Energy Adaptive Clustering Hierarchy-New Optimal Cluster (LEACH-NOC).There are two steps in this algorithm.First,the network is divided into several clusters by the same approach of LEACH,then the nodes near to the centroid of clusters are selected as hea... |
