Adaptive Contention Window for Zone-Based Dissemination of Vehicular Traffic

摘要

Inter-Vehicular Communication (IVC) is very promising for advanced applications in traffic systems. However, current efforts and implementations still require more attention in order to turn such applications into reality. The data dissemination and the vehicular communication are two key concerns in order to make more feasible alternative traffic information systems. In this paper we focus on the traffic data dissemination and the inter-vehicle communication applied to our traffic guidance architecture presented in [5]. We present a twofold proposal: a mechanism for V2I, V2V traffic data dissemination and a simple but efficient mechanism to enhance broadcast communication. We show through extensive evaluations that our composite solution tends to be efficient under the design of our specific application guidelines.
