QoS Measurement of Single-hop Periodic Communication in Vehicular Environment

Life safety on road is the key motivation behind the research in Vehicular Ad-hoc NETwork (VANET). As basic communication mechanism VANET-equipped vehicles broadcast periodic safety beacons to keep the neighboring vehicles aware of the situation at all times. Well known broadcast communication problems i.e. hidden/exposed nodes, collisions and inherent challenges in VANET e.g. dynamic environment, limited bandwidth, are prone to hinder the exchange of potentially lifesaving information. Furthermore, the most of vehicle-to-vehicle broadcast communication will comprise of single-hop periodic safety beacons thus it becomes important to measure their Quality of Service (QoS) under congested vehicular environment.
