无线传感器网络中移动传感器的再定位技术

摘要

By importing mobile sensors and corresponding relocalization algorithms into the wireless sensor networks,problems of further investigation, sensor failure and inaccurate deployment of sensor can be solved. Algorithms for the relocalization of the mobile sensors are introduced in three kinds which are moving to the region of interests for further investigation,expanding coverage area and healing the coverage holes,based on the aim of the moving of mobile sensors. The corresponding main solutions models and future research directions are also summarized and analyzed.%回顾了在传感器网络中引入移动传感器的过程.介绍了移动传感器再定位技术可解决传感器网络中的事件深入感知、传感器失效和非精确投放等问题.详细阐述了现有的移动传感器移动至感兴趣区域深入感知、扩大网络覆盖面积和修补网络覆盖洞三类技术.剖析了现有技术中存在的问题.总结分析了主要解决方法和模型,并对未来研究方向进行了展望.
