A distributed backbone-based framework for live video sharing in VANETs

摘要: Vehicular Ad-Hoc Networks (VANETs) have been expanding their portfolio to support a large variety of services, rang- ing from safety on-road multimedia applications. The distribution real-time videos in Vehicle-to-Vehicle (V2V) fashion allows drivers, passengers, paramedics, and first re- sponder teams capture, share, watch video sequences accidents disasters that happened kilometers away. In this context, the transmission live streams V2V scenarios must be done with Quality Experience (QoE) criteria. This paper introduces DBD (Distributed Beaconless Dissemination) protocol improves delivery flows on highway VANETs, where it is important maintain backbone-based routes for dissemination multi-path opportunistic environments. proposed solution IEEE 802.11p MAC layer solve Spurious Forwarding problem, while increasing packet ratio reducing forwarding delay, especially heavy vehicular traffic conditions caused by accidents, we recreated empirical data. Performance evaluation results show benefits compared existing works VANET scenarios, basis objective subjective QoE measurements.
