基于OPNET的智能交通系统简单场景下的V2I通信性能研究

V2I communication performance of OPNET's intelligent transportation systems based on simple scenarios

车辆通信网络是由汽车上装载的无线通信设备、路边建设的采集基站、传输网络、后台处理服务器及相关采集处理软件组成网络系统,是一个以车辆为采集目标庞大的物联网系统,是车辆内部各部件、车辆与车辆之间、车辆与路边基站之间和车辆与人之间的无线通信网络系统,是智能交通系统的基础信息承载平台。对V2I无线通信网络简单场景进行研究,建立V2I无线数据通信场景,使用OPNET Modeler软件进行建模和仿真,进行智能交通系统简单场景下的V2I无线通信网络总体性能的评估。由于人们对于车辆通信网的认识刚起步,该网络在国内IT领域、学术界和工业界得到广泛的关注,其理论研究和实际应用方面都有很大的研究价值和市场推广价值。

VANET is composed of the vehicle with wireless communication equipment, road construction collecting base station transmission network, background processing server and related acquisition and processing software system. Based on OPNET simulation console, this paper designs a simple V2I scenarios of ITS, simulates its communication process, analyzes the simulation data of sending and receiving, evaluates the entire performance of the network, which can offer reference to designing and optimizing the V2I scenarios.
