无线传感器网络由众多的传感器节点共同组成，传感器节点往往通过随机撒播的方式部署在人为力量无法到达的环境复杂区域进行数据的采集与传输。-Wireless sensor networks is composed of many sensor nodes which are deployed in a complex area beyond men’s approach by means of scattering randomly to collect and transmit the data. Observers can acquire the fruitful answer quickly and directly, and wireless sensor networks perceive, collect and process the monitoring information of the target in a network area cooperatively.
