面向农业监控的动态无线传感器网络路由算法

The Routing Algorithm of Dynamic Wireless Sensor Network for Agriculture Monitoring

无线传感器网络在农业生产的信息采集、处理和远程控制等方面有广阔的应用前景,目前已有的路由算法存在不支持动态网络,或没有考虑移动式基站等问题。提出基于簇的动态的层次型路由算法,算法支持传感器节点和基站的移动性,采用时分多路访问和活动/睡眠机制,以资源丰富的驱动装置作为网关节点管理簇内移动,为农业生产提供更实用的监测方案,仿真结果表明,该算法具有较低的网络能耗。

Wireless sensor networks have broad application prospects in agricultural production,information collection,processing and remote control.The existing routing algorithms do not support dynamic network,or do not consider mobile base station.A cluster-based dynamic hierarchical routing algorithm was presented and supportd the sensor nodes and base station mobility,using time division multiple access and active/sleep mechanism,using resource-rich actuating devices as mobility management inside a cluster to provide more practical monitoring programs for the agricultural production.The simulation result showed that the algorithm had lower network energy consumption.
