无线传感器网络节点定位算法在智能公交系统的应用与比较

无线传感器网络是一种全新的信息获取和处理技术,能够实时监测和采集各种监测对象的信息,应用于公交系统有助于公交系统的智能化,而节点自身定位是其大多数应用的基础。从是否基于测距技术两个角度,总结了五种有代表性基于无线传感器网络的智能公交系统的车辆定位算法,并从定位精确性、适用环境和实现的难易程度三方面对其进行了对比分析。

Wireless sensor networks（WSN）,which is a novel technology about acquiring and processing information, has been proposed for a multitude of location-dependent applications.The application in Traffic System redounded TS to be intelligentized,and node self-localization is a base of most of applications.From the view on whether it based on the ranging technology,five distributed localization algorithms in WSN in ITS are discussed in this paper.All the algorithms are compared and analyzed from three aspects,location accuracy,suitable environment and the difficulties in the implementation.
