Abstract:
Vehicular Ad Hoc Networks (VANETs) are networks formed by vehicles using the wireless medium as communication link for data transmission and reception. In this network, vehicles can transit on the roads with high speed and thus provide a high dynamism in its topology. This may cause the connectivity between vehicle lasts a short time. So, many applications in VANETs, which need to disseminate data traffic seek a fast and efficient diffusion mechanism. The forwarding broadcast mechanism is generally used to accomplish this task. However, a poorly elaborated mechanism for disseminating messages can flood the network with redundant data and increase the number of collisions due to disputes between vehicles for accessing the medium. These problems are usually known as broadcast storm problem. Thus, this paper proposes a probabilistic technique for mitigating the broadcast storm problem through a game from the Games Theory: The Volunteers Dilemma. In order to explore the equilibrium in the game and also evaluate the network technique performance some simulations using the Network Simulator 3 (NS3) were performed. The results showed that the technique presented a good delivery rate of packets and little loss of data with high vehicular densities. However, it was found that even without an overwhelming number of transmissions, a large amount of redundant information was noticed.
