A receiver-based video dissemination solution for vehicular networks with content transmissions decoupled from relay node selection
The provision of video dissemination capabilities over vehicular networks improves the service experience from users side for applications such as heavy traffic notification, hazard warnings and event advertisement. However, the combination of video streamings stringent requirements and the dynamic topology of Vehicular Ad Hoc Networks (VANETs) poses severe challenges for efficient and effective video dissemination. We propose in this work a receiver-based solution that conducts video transmissions decoupled from the relay nodes selection mechanism, namely REDEC. This solution takes advantage of the reactive nature of the receiver-based approach without incurring excessive collisions and overhead due to the transmission of videos large packets at a high frequency. We have also conducted extensive simulation experiments using variety of scenarios with different densities and data exchange rate. Our results indicate clearly that our proposed REDEC protocol outperforms other solutions and is scalable while fulfilling the end-to-end delay requirements of video streaming. Furthermore, we have observed that REDEC also offers higher video reception rates when compared to existing video streaming solutions.
