摘要
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。
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.
