车联网协作感知消息真实生成的经验模型

Empirical Models for the Realistic Generation of Cooperative Awareness Messages in Vehicular Networks

摘要:

大多数V2X(车联网)应用依赖于广播感知消息,在ETSI中称为CAM(协作感知消息),在SAE标准中称为BSM(基本安全消息)。大量的研究致力于保证其可靠的传输。然而,到目前为止,这些研究一般都是基于简化的数据流量模型,这些模型以周期性的间隔或恒定的消息大小生成意识消息。这些模型不能准确地表示遵循特定的基于移动性的规则的CAM消息的真实生成。使用简化和不切实际的交通模型可以显着影响的结果和有效性的研究,因此,准确的模型生成的意识消息是必要的。本文提出了第一套模型,可以真实地生成CAM消息。这些模型是根据两家汽车制造商在城市、郊区和高速公路试驾中收集的真实痕迹创建的。该模型基于m阶马尔可夫源,并对CAM的大小和CAM之间的时间间隔进行建模。这些模型是公开提供给社区的,可以很容易地集成到任何模拟器中。

英文摘要:

Most V2X (Vehicle-to-Everything) applications rely on broadcasting awareness messages known as CAM (Cooperative Awareness Messages) in ETSI or BSM (Basic Safety Message) in SAE standards. A large number of studies have been devoted to guarantee their reliable transmission. However, to date, the studies are generally based on simplified data traffic models that generate awareness messages at periodic intervals or with a constant message size. These models do not accurately represent the real generation of CAM messages that follow specific mobility-based rules. Using simplified and unrealistic traffic models can significantly impact the results and validity of the studies, and hence accurate models for the generation of awareness messages are necessary. This paper proposes the first set of models that can realistically generate CAM messages. The models have been created from real traces collected by two car manufacturers in urban, sub-urban and highway test drives. The models are based on mth order Markov sources, and model the size of CAMs and the time interval between CAMs. The models are openly provided to the community and can be easily integrated into any simulator.
