Abstract

On-road-communications are increasing in relevance, due to the variety of applications for traffic management systems (TMS) and road safety. This interest is enforcing relevant efforts from research community and standardization bodies to support V2V (vehicle to vehicle) and V2I (vehicle to infrastructure) communications. In this framework, an hybrid approach between IEEE 802.11p standard together with LTE is becoming the current state-of-the-art solution to provide the required QoS in vehicular communications. In this direction, several research efforts propose, as a fundamental basis, the formation of virtual groups of vehicles that communicate with 802.11p for V2V and use LTE for V2I transmissions. In this paper we focus on the feasibility and efficiency of forming these mobile groups. We provide simulation and analytical results that show that it is possible to maintain stable connected groups of vehicles at high speeds by increasing the periodicity of control message exchange. Interference in the control channel is the only limitation in this scenario. On the other hand, it is still possible to maintain connected groups of vehicles with low overheads if part of the vehicles, the less stable ones, are disconnected from the groups. These two results are obtained analytically and by simulations in ns-2. The paper also evaluates the effects of the obtained results on the energy efficiency of the system.
在VANETs中稳定的群形成需要多少开销?
由于交通管理系统(TMS)和道路安全的各种应用,道路上通信的相关性正在增加。这种兴趣促使研究团体和标准化机构做出相关努力,以支持V2V(车对车)和V2I(车对基础设施)通信。在此框架下,IEEE 802.11p标准与LTE之间的混合方法正在成为当前最先进的解决方案,以提供车辆通信所需的QoS。在这个方向上,一些研究工作提出,作为一个基本基础,形成虚拟车辆组,使用802.11p进行V2V通信,使用LTE进行V2I传输。本文重点讨论了形成这些移动群的可行性和效率。我们提供的仿真和分析结果表明,通过增加控制信息交换的周期性,可以在高速下保持稳定的车辆连接组。在这种情况下,控制信道中的干扰是唯一的限制。另一方面,如果部分不太稳定的车辆从组中断开,仍有可能以低开销维持连接的车辆组。这两个结果在ns-2中得到了解析和模拟。本文还对所得结果对系统能效的影响进行了评价。
