一种新的无线传感器网络节点自定位技术

在无线传感器网络中，节点定位技术是许多应用的支撑技术，具有重要地位。目前已经出现各种各样的定位算法，KPS 算法不需要测距，具有一定的优越性，但在某些应用中存在定位精度较低的问题。针对这一问题，提出了一种新的改进KPS 定位精度的算法，仿真结果表明，该改进算法能够明显提高定位精度。

A New Self-localization Technology for Wireless Sensor Network Nodes ZHANG Zheng-yong1 MEI Sun-liang1 HAN Ming2 (1.Department of Electronic Engineering,Tsinghua University,Beijing 100084) (2.Academy of Air Force Arming,Beijing 100084) Abstract:In wireless sensor networks ,sensor location plays a critical role in many application. In the past,a number of location discovery schemes have been proposed.KPS has an advantage because no distance/angle measurement among nodes is involved,but high inaccuracy as compared to others.This paper proposes a new location algorithm to improve the inaccuracy of KPS.This paper has conducted simulations to evaluate the
scheme.
