一种基于时间延迟机制的无线传感器网络分簇算法
A Clustering Hierarchy Arithmetic Based on Time Delay for Wireless Sensor Networks
摘要
Abstract
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 a-rithmetic 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 in each round. Besides this,a set of nodes that have received cluster heads information is proposed so that the algorithm is able to ensure a constant number of cluster heads and the cluster heads are well scattered. Simulation results demonstrate that CHTD algorithm effectively balances the energy dispatch of the sensors and obvious improvement on the network lifetime.关键词
