Paper Abstract:	Digital TV broadcasting service will increase opportunities to receive TV broadcasts with a mobile node like a cellular phone, and the spread of high-speed wireless communication services for IP-based mobile phones will spur the development of services delivering high-quality multimedia content through the Internet. Delivering TV content through mobile internet connections will increase the load on content-delivery servers, making it necessary to use a distributed content delivery system that can control the load-balance of the server and network traffic. We therefore propose a P2Pbased distributed multimedia content delivery system that uses ad hoc WiFi networks together with cellular networks. In the proposed system, each mobile node separately receives different parts of the target content through a cellular network and shares its content parts with other nodes through an ad hoc WiFi network in order to build the target content. This decreases the cellular network’s traffic and content-delivery server’s load because the server does not need to send all the target content to every node, and. Our evaluation results show that the proposed system is more effective than the conventional bucket-brigade system.
