A new adaptive algorithm for data dissemination in Vehicular Ad hoc Networks

The idea or concept of intelligent traffic management in which data from the TIC (Traffic Information Centre) infrastructures could be reachable at any point is included mightily in Smart cities. Living labs (cities in which new designed systems can be tested in real conditions) have been created all over Europe to test the possibilities of these future cities. It’s the new concept where vehicular networks play relevant role. The Vehicular Ad-hoc Networks VANETs are a sub-class of the most studied Mobile Adhoc Networks MANET, in which vehicles are considered as mobile nodes. VANETs differ from other MANETs because of their specific characteristics, inducing numerous problems and constraints, which lead us to discuss many issues in VANETs as they are decentralized, self organized, self monitoring with distributed nature of network.

When and if deployed, VANETs will be the most implemented MANET ever and will continue their development over next years; it is indeed the reason why many issues are of great concern to be studied. Ample research efforts have been devoted to VANETs in the broadcasting domain. In order to have optimal and adaptive approaches, we focus on a number of requirements. In this light, this article will present an overview of VANETs, chiefly broadcasting protocols with the aim to resolve this relevant related issue, it also present some suggested broadcasting solutions and a propose a new algorithm with the idea of integrating the concept of Intelligent Traffic Lights ITLs in order to solve the core’s problem which is how to minimize the number of rebroadcast packets while maintaining good latency and reachability using dynamic parameters from the counter, probability based and distance based.
