پروژه QoE-Driven User-Centric VoD Services in Urban Multihomed P2P-Based Vehicular Networks با NS2

چکیده مقاله:

Recently, many cities around the world have witnessed large-scale deployment of terrestrial broadcasting mobile television (TV) to vehicles This service is similar to the cable or satellite TV already in the home, and user-centric interactive mobile Video-on-Demand (VoD) over urban vehicular networks is in fact expected However, providing this new service with focus on user Quality of Experience (QoE) constitutes a significant challenge This paper introduces a  QoE-driven User-centric solution for VoD services in urban vehicular network environments QUVoD QUVoD relies on a multihomed hierarchical peer-to-peer (P2P) and vehicular ad-hoc network (VANET) architecture. Vehicles construct a low-layer VANET via Wireless Access in the Vehicular Environment interfaces; they also form an upper layer P2P Chord overlay on top of a cellular network via Fourth-Generation (4G) interfaces A novel grouping-based storage strategy that uniformly distributes the video segments along the Chord overlay is proposed, reducing segment eeking traffic while also enabling load balancing A novel segment seeking and multipath delivery scheme that achieves high lookup success rate and very good video data delivery efficiency is also introduced , which achieves high lookup success rate and very good video data delivery efficiency Furthermore, a new speculation-based prefetching strategy is proposed, which analyses users’ interactive.
