摘要

WSN中的定位是利用已知锚节点的位置来确定节点的位置。在许多满足粗精度要求的应用中,人们追求无距离定位机制来替代基于距离的定位机制。由于无距离定位方案成本低,能耗低。本文提出了一种基于Mamdani & Suggano模糊推理系统的三维无线传感器网络无距离加权质心定位方法。首先将锚节点连接到定位于发现的未知节点(传感器节点),然后利用Mamdani & Sugano推理系统根据接收到的信号强度指标信息(RSSI)计算锚节点的边权。通过大量的仿真,将加权质心技术与简单质心技术进行了比较。仿真结果表明了三维加权质心方案的有效性。

Localization of 3D WSN using Mamdani Sugano fuzzy weighted centriod approaches
Localization in WSN used to determine the position of node with the help of known positions of anchor nodes. In many of the applications, where coarse accuracy is sufficient, range free localization mechanism are being pursued alternative to range based localization mechanism. Because the range free localization scheme is low cost and consumes low energy. In this paper, we present range free weighted centroid localization for 3D WSN using Mamdani & Suggano Fuzzy Inference System. In this first anchor nodes are connected to unknown nodes (sensor nodes) localized to found, after this edge weight of anchor nodes are calculated based on received signal strength indicator information (RSSI) by using Mamdani & Sugano inference system. We compare the weighted centroid technique, through extensive simulation with simple centroid. The simulation result represent the effectiveness of 3D weighted centroid scheme.
