一种改进的DV-Hop无线传感器网络定位算法

基于DV-Hop的无线传感器网络定位算法采用三边测量法计算位置,具有能量消耗大的问题,采用了一种MIN-MAX 方法计算节点位置.通过减少计算开销,降低能量消耗,从而延长无线传感器网络的生存周期.实验表明改进后的算法能够大量减少计算开销,而且还能略微提高定位精度.

A Improved DV-Hop Localization Algorithm of Wireless Sensor Networks

Based on the DV-Hop wireless sensor network location algorithm using triangular measurement method calculate position,with a large consumption of energy issues.This paper uses a method of calculating MIN-MAX node location,by reducing calculation spending,reducing energy consumption,thus prolonging the survival of wireless sensor networks cycle.The experiments show that the improved algorithm can substantially reduce computing costs,but also slightly improved positioning accuracy.
