摘要
无线传感器网络在精细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基本没有考虑节能和丢包率的问题,影响网络的寿命和监控的准确性.文章提出一种高效节能的合作式路由算法,算法采用活动/睡眠机制和简单的路由选择方案,有效地节省了网络能耗;高效的数据传输算法大大地降低了网络的丢包率.仿真结果表明,该算法具有低能耗和高可靠性,适用于现代精细农业监控.
Wireless sensor networks in precision agricultural production,information collection,processing and remote control have broad application prospects. The existing routing algorithms do not consider the issue of energy efficiency and packet loss rate,which af?fects the lifetime of network and the accuracy of monitoring. This paper presents an energy-efficient and cooperative routing algorithm which adopts active or sleepy mechanism and the simple routing scheme effectively to save energy consumption. The highly efficient data transmission algorithm greatly reduces the packet loss rate of network. Simulation results show that the algorithm has low network energy consumption and high reliability for precision agriculture applications.
