Generally speaking, Vehicular Ad hoc Networks comprise vehicles and roadside stations as the common types of nodes. These nodes are mainly providing each other with relevant information. A wide range of applications are supported by Vehicular Ad hoc Networks such as file downloading, or access to the Internet with lack of resource controlling. These challenging resource managements degrade the network performance and create competitive environments. Through this paper, we introduce a novel algorithm for bandwidth sharing enhancement in both vehicle-to-vehicle and vehicle-to-roadside communications. We aim to improve the bandwidth usage based on coalition formation game in order to reduce the cost paid by vehicles for bandwidth reservation at roadsides. Mainly, we intend the enhancement of both individual vehicles’ payoff along with the whole network gain. Simulation results have proven that the proposed algorithm succeed to analyze this conflicting situation efficiently. In addition, satisfaction rates up to 75% have been achieved with an incredibly increase in the network throughput.
