在無線傳感器網絡中，節點定位技術是許多應用的支撐技術，具有重要地位。目前已經出現各種各樣的定位算法，KPS 算法不需要測距，具有一定的優越性，但在某些應用中存在定位精度較低的問題。針對這一問題，提出了一種新的改進KPS 定位精度的算法，仿真結果表明，該改進算法能夠明顯提高定位精度。

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.
