面向农业监控的动态无线传感器网络路由算法

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.

The Routing Algorithm of Dynamic Wireless Sensor Network for Agriculture Monitoring

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.
