车辆到车辆(V2V)和车辆到基础设施(V2I)通信在提高道路安全和舒适性方面发挥着重要作用。汽车之间的通信通常被称为车载自组织网络(VANET)，它具有减少汽车事故、最大限度地减少交通拥堵、降低油耗和排放等优点。车载信标是一种重要的通信方式，用于将一辆车的信息广播给相邻的车。本文基于IEEE 802.11p标准，对实际大规模城市区域(真实交通和地图)中的车对车通信进行了仿真，并研究了成功信标的投递率。本研究计算了真实仿真中的信标投递概率，并与数学模型进行了比较。计算了汽车在不同情况下的PBD(例如，城市中一辆特定汽车的PBD，街道上的一组汽车，十字路口的汽车，不同交通密度的大区域的PBD等)。在实际应用之前，有必要对802.11p的PBD进行研究，以确定该技术是否有效。这项研究是第一次在现实的大城市地区对802.11p的PBD进行研究。结果表明，802.11p在车流密集的大面积区域的PBD很低。此外，本研究还对不同的VANET模拟器进行了研究。因此，本文选择了用于交通仿真的SUMO、用于网络仿真的OMNeT++以及将OMNeT++与SUMO相结合的VENTES框架。
Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communication are playing an important role in improving the road safety and comfort. Communication between cars often referred to vehicular ad-hoc networks (VANET) has many advantages such as reducing cars accidents, minimizing the traffic jam, reducing fuel consumption and emissions, etc. VANET architecture has been standardized in the IEEE 802.11p specification. VANETs beaconing is one of the most important communication modes, which is used to broadcast the information of a car to the neighbour cars. This paper deals with simulation of car to car communication in realistic large-scale urban area (real traffic and map) based on IEEE 802.11p standard and investigates the successful beacon delivery probability. This study calculates the Probability of Beacon Delivery (PBD) in realistic simulation and compares that with the mathematical model. PBD for cars in different situations are calculated (for example PBD for one particular car in the city, one group of cars in the street, cars in the crossroad, PBD in a large area with different traffic density, etc.). Studying the PBD of 802.11p is necessary to find out whether this technology is effective before implementing in the real world. This study is the first study performed on the PBD of 802.11p in realistic large urban area. The results show that the PBD of 802.11p in a large area with huge density of cars is quite low. In addition, in this study different VANET simulators are investigated. As a result SUMO for traffic simulation, OMNeT++ for Network Simulation and Veins framework for integration of OMNeT++ and SUMO are selected in this study.
