摘要
针对停车场自动化管理的智能交通难题,对利用车辆无线传感器网络对车位检测的辅助定位进行了研究。首先讨论无线传感器网络技术在国内外的发展现状并进行分析,然后提出了一个停车场无线传感器网络设计的总体概述,接着对车辆传感器网络辅助定位的理论进行了深入的分析,最后详细地给出了计算车辆传感器网络广播协议的消息交换的复杂度和消息传输总时间复杂度的计算式。
This paper focuses on the automated parking management problem and studies the assisted positioning of the parking space detection with the help of wireless sensor network. First it discusses the current development of the wireless sensor network technology at home and abroad, and analyzes them. Then it presents a general overview of a parking sensor network design. After that, it conducts an in-depth analysis of the vehicle wireless sensor network assisted positioning theory. Finally, it gives the formulas of the complexity of message exchange and the total time complexity of message transmission for vehicle sensor network broadcast protocol.
