Analysis of multi-hop broadcast in vehicular ad hoc networks: A reliability perspective

Intelligent Transportation Systems (ITS), supporting the development of innovative vehicular applications, have benefited from major contributions in the field of wireless networking. Broadcasting is a crucial communication type for many domain-specific applications. In this work we focus on analytical modeling of multi-hop broadcast in vehicular networks and quantify its performance in terms of relevant indicators, by taking into account the effect of main parameters. Our model is based on the network topology and as a result, the major network characteristics such as vehicle density and the number of 1-hop neighbors, affecting dissemination penetration rate, are considered in the model. Through extensive experiments, confirming the substantial impact of the network topology and the connectivity regime on the overall broadcast performance, we provide insight into the system functionality. Such observations can be used as feedback for further performance optimization in various network conditions.
