一种基于时间延迟机制的无线传感器网络分簇算法

为了延长网络的生存时间,需要设计能量有效的路由协议以适应传感器网络的特点.成簇算法是传感器网络中减少能量消耗的一种关键技术,它能够提高网络的生存时间.本文提出一种基于时间延迟机制的分簇算法,称为CHTD.该算法建立了节点的时间延迟机制模型,使得能量较多的节点能够在每一轮中被优先选为簇首.同时,通过维持每个节点的簇首信息集合使得每轮产生的簇首数目稳定且位置均匀分布.模拟实验表明,CHTD有效地均衡了网络中节点的能量消耗,并显著地延长了网络的存活时间.

A Clustering Hierarchy Arithmetic Based on Time Delay for Wireless Sensor Networks

In order to prolong the network lifetime,energy-efficient routing protocols should be designed to adapt the characteristic of wireless sensor networks.Clustering algorithm is a kind of key technique used to reduce energy consumption,which can make a longer life span of sensor network.A clustering hierarchy arithmetic based on time delay(CHTD)was presented,Taking use of the sensor nodes time delay module,it can guarantee the node with high remaining energy to be chosen as the cluster head nodes in priority i...
