摘要
把成百上千的价格便宜的微传感器节点组成网络,并且智能地把所有单个节点搜集到的信息融合,使用者就可以精确地采集远方区域上他感兴趣的信息。这些无线网络的路由协议必须健壮性很强,节省能量并且延迟很小。基于经典的LEACH(LowEnergyAdaptiveClusteringHierarchy)协议,提出了对它的改进:主要是使用了新的策略来确定最优的簇数目。最后,该文算法和多跳路由、直接路由、LEACH进行了仿真比较,结果证明使用该文算法后系统的生存时间增长。
Networking together hundreds or thousands of cheap microsensor nodes allows users to accurately monitor a remote environment by intelligently combining the data from the individual nodes.These wireless networks require robust routing protocols that are energy efficient and provide low latency.Starting from the basic idea of classical LEACH(Low Energy Adaptive Clustering Hierarchy),this paper introduces some innovations in the algorithm giving origin to NEW_LEACH.NEW_LEACH presents a new strategy of cluster heads election and cluster formation.The simulation re-sults show that NEW_LEACH achieves great advance in system's lifetime.
