Robust mid-range communication in Urban VANETs

Cooperative driving and the associated need for vehicular communication motivate vehicular ad-hoc networks (VANETs). One major challenge is to provide for robust communication - in spite of highly dynamic topologies and the presence of shielding obstacles - without installing extra relay infrastructure. Traffic-density information and density estimation schemes are a valuable asset to approach this challenge. In this light we propose a novel routing protocol. Furthermore, extensive simulations are provided to support our case.
