Military defense, disaster monitoring, rescue and other harsh or dangerous environments are the typical applications of wireless sensor networks (WSNs). For these types of application environments, a mobile multi-Sink wireless sensor networks based monitoring system is designed and constructed, which can gather the surrounding information, control and monitor the mobile Sink nodes, locate the position of events, and interact with each nodes by multi-model methods. Experimental results show that, when 2 mobile sink nodes are in network, the average network delay is less than 100 ms, and average packet-loss-ratio is less than 5％. So this system is suitable for the applications which are not care the network real-time capability.%军事防御、灾害监测与救援等危险/恶劣环境监测是无线传感器网络的典型应用.在此面向危险/恶劣环境监测需求,设计并构建移动多Sink无线传感器网络监测系统,实现环境信息感知、便携式移动指挥、事件定位、移动用户生理监护、多模态(语音、图像、文字等)交互等功能.实验测试结果表明,当网络中存在2个移动Sink节点时,网络平均延时小于100 ms,网络丢包率小于6%,可满足网络实时性要求不高的应用.
