摘    要:应用无线传感器网络进行农田信息采集时,针对农田面积大、传感器节点众多的特点,如何有效地部署节点成为研究的热点之一。利用NS2软件从丢包率、平均延时、剩余能量和接收信号强度等网络性能角度对随机部署、正六边形部署及正四边形部署方式进行了仿真比较,最终确定正六边形部署方案,并在农田中进行实地试验。结果表明系统能够实现无缝覆盖,稳定可靠的采集农田信息,为无线传感器网络在农田环境中的进一步应用提供了参考。

关 键 词:无线传感器网络(WSN)  环境监测  传感器  NS2软件  节点部署

Abstract:In farmland information collection system which based on the wireless sensor networks, effective deployment of nodes becomes one of the research priorities, due to the is large number of sensor nodes laid in wide area of farmland. NS2 software executed the simulation comparison from the following aspects such as packet loss rate, average delay, the remaining energy of sensor nodes. The hexagonal plan was determined as the final deployment one, and experiments were carried out in the fields. Results showed that the system could achieve seamless coverage, and acquire the field information stably and reliably, which laid the solid foundation for further application infield wireless sensor networks.
Keywords:wireless sensor networks   environmental testing   sensors   NS2 software   node deployment
