Abstract :
Video content delivery for vehicular ad hoc networks (VANET) under dense network conditions poses non trivial issues because of the scarcity and volatility of the wireless medium. In this context, video communication is envisioned to be of high benefit for traffic management as well as for providing value-added entertainment and advertising services. In this paper, we propose a new mechanism for efficient video streaming over VANET. The proposed mechanism selects a minimum sub-set of rebroadcaster vehicles in order to reduce interferences and achieve high video quality. The vehicles are ranked based on their strategic location in the network and their capacity to reach other vehicles using a new centrality metric inspired from the Social Network Analysis (SNA), called dissemination capacity. Through simulations, we compared our mechanism with the multichannel vehicular communication standard IEEE 1609.4 and another pioneering video streaming mechanism over VANET. The performance evaluation shows that it outperforms the abovementioned mechanisms by providing higher video delivery ratio, lower end- to-end transmission delay and lower frame loss ratio in both fully and intermittently connected networks.
