摘要
在无线传感器网络(W SNs)中,通过对节点的定位以确定事件发生的位置是W SNs需要具备的基本功能。介绍了W SNs定位技术的国内外研究现状,分析了静态传感器网络定位、移动信标节点定位和移动传感器网络定位的原理及方法,讨论了几种主要算法的优缺点,给出了移动传感器网络定位技术进一步研究的方向与面临的挑战。
In wireless sensor networks( WSNs), it is a basic function of WSNs to determine the position of sensor nodes based on node location. The current research status of WSNs location techniques at home and abroad are introduced, the location principle and methods of static WSNs, mobile-assisted WSNs and mobile WSNs locations are analyzed, the main advantages and disadvantages of several main algorithms are discussed. The challenges and research direction of mobile WSNs location techniques are provided.
