P2P 기반 주문형 비디오 시스템에서 모바일 장치 지원에 대한 연구

Supporting Mobile Devices in Peer-to-Peer Video-on-Demand Systems

Peer-to-Peer (P2P) network has great potential on utilizing the network while reducing the server loads. Video on Demand (VoD) has become widely used since we can watch contents we like without having to download the overall file first. The mobile users may not need high quality of video; they only need good enough quality that can be played in the limited resource of physical device and network. So does with the devices with very limited network bandwidth. These issues emerge an idea of allowing Free-Rider in the P2P VoD system, where those low performance devices will only optimize the network utilization, affecting none to the performance of main system.
