Exploiting Multi-Hop Connectivity for Dynamic Routing in VANETs

Recent vehicular routing proposals dynamically select forwarding paths based on real-time traffic information, mostly the vehicular density, and route the packets to the final destination using the sender-based forwarding approach. However, estimating the vehicular density can require a significant communications overhead, and the adoption of sender-based forwarding can increase the presence of unreliable radio links in multi-hop transmissions. In this context, this paper presents a novel contention-based forwarding protocol that dynamically selects routing paths based on their multi-hop connectivity.
