摘要

协作定位提高了定位估计的准确性，特别是在锚点稀疏部署的网络中。本文介绍了其在低成本、低功耗无线传感器网络中的实现。给出了一种具有超宽带测距和通信功能的无线传感器网络硬件平台，并讨论了基于信念传播的协同定位算法的应用。采用简单的通道接入方案和标准的测距方法，讨论了系统的主要误差来源，并对系统进行了室内评价。

WSN Implementation of Cooperative Localization

Cooperative localization increases the accuracy of location estimates especially in networks with sparse anchor deployment. In this work, its implementation in low-cost low-power wireless sensor networks is presented. A WSN hardware platform with ultra-wideband ranging and communication is shown and the application of a belief propagation based cooperative localization algorithm discussed. With a simple channel access scheme and a standard ranging method, the main sources of error are discussed and indoor evaluations of the system are conducted.
