【摘要】：随着车辆交通朝着网络化和智能化的方向不断发展，智能交通系统(ITS)已经成为一个热门的研究课题，，行车过程中的即时通信作为ITS的一个重要组成部分，在日常生活中有很大的需求。但遗憾的是，目前并没有一个标准的完全适用于车辆环境的即时通信系统。本文从这个问题出发，通过对即时通信标准协议XMPP和车辆通信标准WAVE的学习和研究，把二者结合起来，研究了一种基于WAVE和XMPP的车载即时通信系统解决方案。本文研究的方案根据组建方法的不同分为三类，分别是基于中心服务器的车载即时通信系统、基于分布式服务器的车载即时通信系统和基于P2P的车载即时通信系统。同时本文对这三种不同方法进行了较为详细的阐述，包括各自相应的网络部署结构、协议框架、通信流程以及优缺点。然后本文对文中研究的车载即时通信系统进行了功能模块的设计，包括即时通信系统的服务器和客户端的各个功能模块的设计。之后本文在开源开发平台Android下对文中研究的车载即时通信系统进行了主要功能模块的具体实现，并对开发出的Android即时通信应用在Wi-Fi环境下进行了具体的部署测试。测试结果表明，本文所研究的解决方案可以满足车载即时通信的基本功能需求，具有一定的实用性。
[Abstract]:With the continuous development of vehicle traffic towards the direction of network and intelligence, Intelligent Transportation system (its) has become a hot research topic. The instant communication in the driving process is an important part of ITS.There is a great demand in daily life.Unfortunately, there is no standard instant messaging system that is fully applicable to vehicle environments.From this point of view, through the study and research of XMPP and WAVE, a solution of on-board instant communication system based on WAVE and XMPP is studied.The schemes studied in this paper can be divided into three categories according to the different methods. They are the in-vehicle instant communication system based on the central server, the in-vehicle instant communication system based on the distributed server and the in-vehicle instant communication system based on P2P.At the same time, the three different methods are described in detail, including the corresponding network deployment structure, protocol framework, communication flow, advantages and disadvantages.Then, the paper designs the functional modules of the vehicle instant communication system, including the design of the server and the client of the instant communication system.Then this paper implements the main functional modules of the in-vehicle instant communication system under the open source development platform Android, and carries on the concrete deployment test to the developed Android instant communication application under the Wi-Fi environment.The test results show that the solution studied in this paper can meet the basic functional requirements of in-vehicle instant communication and has certain practicability.
