摘要

随着无线传感网定位技术的发展，高精度、大范围、低代价成为无线传感器网络定位技术的研究热点.文中提出一种用于无线传感网定位的协作波纹算法，侧重于对多节点实现快速精确定位. 首先以更合理的网络布局研究为基础，设计一种可以拼接的网络拓扑结构；其次利用节点协作的方式感知网络环境，降低定位误差；最后利用波纹定位的方式对节点进行两轮定位，从而实现网络区域内的高精度定位. 仿真实验表明，网络的锚节点节省率可达3.20%，定位精度提升了20.00%，进而充分证明了协作波纹算法的有效性与合理性.

Abstract

This paper proposes a collaboration ripple algorithm for high accuracy, large range and low cost localization of large scale nodes in a wireless sensor network (WSN). A splicing network topology is designed based on a rational network topology research. Location error is reduced with collaboration among the nodes. The ripple algorithm is applied to locate unknown nodes in a unit cell to realize accurate localization of
neighboring notes. Verification of the algorithm shows that the collaboration ripple location algorithm can reduce anchor nodes by 3.20%, and improve precision by 20.00%, indicating effectiveness of the proposed algorithm.

Key words： wireless sensor network (WSN); localization; high accuracy; network topology divide; collaboration ripple localization algorithm
