A Seamless Quality-Driven Multi-Hop Data Delivery Scheme for Video Streaming in Urban VANET Scenarios

In this paper, the authors propose an integrated network-layer scheme for seamless delivery of video packets in VANET. First, they introduce a new quality-driven routing scheme for delivering video streams from a fixed network to a destination vehicle via multi-hop communications. The routing scheme aims to optimize the visual quality of the transmitted video frames by minimizing the distortion, the start-up delay, and the frequency of the streaming freezes. They then propose an efficient network mobility management scheme, which introduces a novel adaptation of Proxy Mobile IPv6 (PMIPv6) for multi-hop VANET scenarios, and incorporates a handover prediction mechanism.
