A Study of Live Video Streaming over Highway Vehicular Ad hoc Networks
Meenakshi Mittal · International Journal of Computer Applications · 2010
The main goal of VANET is providing safety and comfort for passengers. Live Video streaming over Vehicular Ad hoc Networks (VANET) is important for many applications, like online games, Collision warning, road sign alarms, emergency live video transmission and road-side video advertisement broadcasting. Vehicles have sufficient bandwidth, computation and storage capacity to support data intensive communication, the high mobility may cause persistent network partition. All or most vehicles have wireless communication devices installed along with an elaborate road side infrastructure. In the video streaming environment the video source can be a typical video server, while the video receivers are vehicles that are driving on the road. In this video server forward video data to nearby vehicle and thus data is received by the appropriate user or vehicle. In this paper, we focus on video streaming between vehicles in highway, where the traffic density is adequate to mitigate frequent link disconnections and persistent network partitions. This technique adopts a store-carry-and-forward approach to transmit video data in a partitioned network environment. This proposal can help us to increase the performance and can avoid packet loss in live video streaming over vehicular ad hoc network.
