在無(wú)線傳感器網(wǎng)絡(luò)中，節(jié)點(diǎn)定位技術(shù)是許多應(yīng)用的支撐技術(shù)，具有重要地位。目前已經(jīng)出現(xiàn)各種各樣的定位算法，KPS 算法不需要測(cè)距，具有一定的優(yōu)越性，但在某些應(yīng)用中存在定位精度較低的問(wèn)題。針對(duì)這一問(wèn)題，提出了一種新的改進(jìn)KPS 定位精度的算法，仿真結(jié)果表明，該改進(jìn)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.
