在过去的几年中，车辆间通信（IVC）已经成为一个主要的话题。在FleetNet项目中，将开发一种新型的移动的ad hoc网络--基于UMTS陆地无线电接入时分双工（UTRA TDD）空中接口--通过移动的互联网将车辆和路边网关互连。在本文中，我们专注于车辆交通动态的影响，特别是媒体接入，它支持QoS的资源预留的Ad Hoc网络协议。基于车辆交通理论的分析分布和现实的交通情况下，我们开发的ad hoc网络协议的要求和依赖关系。从结果可以得出结论，所提出的基于UTRA TDD的修改的MAC方案可以科普典型的网络拓扑结构的变化，如车辆环境所期望的。
Inter Vehicle Communication (IVC) has become a major topic during the last few years. Within the FleetNet project a novel mobile ad hoc network will be developed – based on the UMTS Terrestrial Radio Access Time Division Duplex (UTRA TDD) air-interface – to interconnect vehicles and roadside gateways via a mobile Internet. In this paper we focus on the impacts of vehicular traffic dynamics on protocols for ad hoc networks, specifically the medium access, which supports QoS by means of resource reservation. Based on analytical distributions of vehicular traffic theory and on realistic traffic scenarios we develop requirements and dependencies of the developed protocols for ad hoc networks. From the results it can be concluded that the proposed modified MAC scheme based on UTRA TDD can cope with typical network topology changes as expected for vehicular environments.
