无线传感器网络序列定位改进算法研究

Study on improved sequence-based localization in WSNs

分析无线传感器网络序列定位原理,解决2个问题:首先对定位过程涉及的距离与接收信号强度2类参数的比较提出更为合理的方法,其次对基于定位空间点、边和面等不同区域划分后定位质心的求解引入有效的计算公式,仿真实验验证了方法的有效性.

This paper analyzes the sequence localization principle of wireless sensor networks,and solves the two questions.The first is to propose a reasonable approach for comparing range and received signal strength.The second is to introduce a new centroid definition based on partition of vertices,edges and faces in localization areas.Simulation results demonstrate the effectiveness of the methods.
