摘要
无线车载网络是智能交通系统的重要组成部分,具有广泛应用前景,而且是物联网应用的重要分支.总结车载网络中传统传输技术的发展,概括传统传输技术的局限性.阐述了机会路由基本原理;然后归纳了机会路由在车载网络中的发展现状,尤其重点分析了位置相关的机会传输、基于导航系统的机会传输和基于网络编码的机会传输在车载网络中的应用,指出了现有机会传输在车载网络中应用的不足;最后对车载网络中的进一步的研究方向进行展望.
Vehicular Ad hoc Networks is an important component of intelligent transportation system, and has widely application pros-pect. It is an important branch of Internet of things. Firstly, the traditional routing research of Vehicular Ad hoc Networks is summa-rized. The basic idea of opportunistic routing is introduced. Furthermore, the latest research of transmission of Vehicular Ad hoc Net-works based on opportunistic routing is summarized. Technical limitations of the traditional transmission is summarized in the paper. We focus on the analysis of the opportunistic transmission based on position, opportunistic transmission based on the navigation sys-tem, and the opportunistic based on network coding in particular respectively. Further, we point out that insufficiency in the existing opportunities for transmission in the Vehicular Ad hoc Networks. In conclusion, the open issues for opportunistic routing referring to application based on the analysis in Vehicular Ad hoc Networks are pointed out.
