农业生产环境监测无线传感器网络路由算法研究
Research of Wireless Sensor Network Routing Algorithm for Agricultural Environment Monitoring
摘要
Abstract
With the characteristics of low cost,low power consumption,high reliability and self -organi-zation,wireless sensor networks (WSNs)play important roles in the agricultural production environment moni-toring.Aiming at the problem of cluster head nodes consuming energy so fast to lead the network segmented into parts,we put forward an event driven and energy efficient clustering routing algorithm for agricultural pro-duction environment monitoring.All nodes go to sleep mode after the network deployment,when the monitored parameter’s value higher than the setting threshold,the nodes within the scope are awakened and start the in-cident response clustering mechanism.At the cluster set up phase,randomly select a node as elector to broad-cast request clustering message,and accept the other sensor nodes’response,according to each node energy situation,elector choose node with the maximum residual energy as a cluster head,and choose node with sec-ond highest energy for the next round elector.In data transmission phase,the relay nodes were selected on the basis of the residual energy of nodes and the distance to the base station (BS).The simulation experimental results showed that the proposed protocol could reduce the communication overhead between the cluster mem-bers,effectively balance the energy consumption of each node in the network,and significantly prolong the survival time of the network.关键词
