Infrastructure-Aid Information Forwarding Based on Network Coding in Vehicular Ad Hoc Networks

摘要

In this paper, we present an analytical study for data dissemination in vehicular ad hoc networks (VANET) in the urban areas. Without any routing protocol, random linear network coding (RLNC) is an efficient method in practical scenarios contrasted with flooding. In such scenarios, some vehicles cannot communicate with others due to their mobility and non-connection with the neighbors. To tackle this problem, we propose a mechanism using the roadside infrastructure to assist transmission, which allows the majority of vehicles in a connected domain. Through this mechanism, the packets delivery ratio is improved significantly and other properties are minimally affected. Furthermore, the feasibility of this approach is verified through the simulations.
