A MP2P-based VoD solution for supporting VCR-like operations in MANETs

Mobile Peer-to-Peer (MP2P) network is a promising avenue for large-scale deployment of Video-on-Demand (VoD) applications over mobile ad-hoc networks (MANETs). In P2P VoD systems, fast search for resources is key determinants for improving the Quality of Service (QoS) due to the low delay of seeking resources caused by streaming interactivity. In this paper, we propose a MP2P-based VoD (MPV) solution for efficient video resource sharing in MANETs. By estimating the popularity of video chunks and association level between chunks, MPV divides the chunks into two types: “overlay router” chunk and ordinary chunk and builds the “virtual connection” between them. MPV chooses a node for each “overlay router” chunk as “overlay router” to provide the service of seeking resource for overlay nodes. Thorough simulation results also show how MPV achieves lower average end-to-end delay, lower packet loss ratio and higher network throughput in comparison with another state of the art solution.
