多应用场景下的车联网功率和速率控制

Power and Packet Rate Control for Vehicular Networks in Multi-Application Scenarios

Miguel Sepulcre, Javier Gozalvez, M. Carmen Lucas-Estañ

摘要:

车载网络要求车辆定期发送1跳广播数据包,以便检测其本地邻域中的其他车辆。许多车辆应用依赖于在公共控制信道上发送的这些分组的正确接收。实际上,车辆将被要求同时执行多个应用程序。因此,广播分组的传输应当被配置为在控制信道负载的同时满足所有应用的要求。当车辆同时运行多个应用程序时,这可能具有挑战性,并且每个应用程序具有随车辆环境而变化的不同要求(例如速度和密度)。在这种情况下,本文提出并评估了不同的技术,以动态地适应每辆车的1跳广播数据包的速率和功率在多个应用场景。所提出的技术旨在满足多个同时应用的要求,并减少信道负载。评估结果表明,所提出的技术显着降低了信道负载,并能更好地满足多个应用程序的要求相比,现有的方法,特别是在SAE J2735 DSRC消息集字典中规定的消息转发。

英文摘要:

Vehicular networks require vehicles to periodically transmit 1-hop broadcast packets in order to detect other vehicles in their local neighborhood. Many vehicular applications depend on the correct reception of these packets that are transmitted on a common control channel. Vehicles will actually be required to simultaneously execute multiple applications. The transmission of the broadcast packets should hence be configured to satisfy the requirements of all applications while controlling the channel load. This can be challenging when vehicles simultaneously run multiple applications, and each application has different requirements that vary with the vehicular context (e.g. speed and density). In this context, this paper proposes and evaluates different techniques to dynamically adapt the rate and power of 1-hop broadcast packets per vehicle in multi-application scenarios. The proposed techniques are designed to satisfy the requirements of multiple simultaneous applications and reduce the channel load. The evaluation shows that the proposed techniques significantly decrease the channel load, and can better satisfy the requirements of multiple applications compared to existing approaches, in particular the Message Handler specified in the SAE J2735 DSRC Message Set Dictionary.
