Nowadays, mobile-oriented video delivery services, especially MPEG format video contents, have diversified with the increasing popularity of smart phones equipped with Wi-Fi functions and the rapid development of wireless networks, providing mobile users with an unprecedentedly convenient business and entertainment environment. One of the problems in video delivery service is that concentrated access from numerous mobile devices sometimes leads to overloads of service servers. P2P has been applied as a solution to this, however, exchanges among peers produce high network traffic. Also, simultaneous data relays generate congestion at routing nodes, compounding the explosion of data content; these factors are becoming important for determining the quality of services. Network coding has been proposed to improve network performance, however, packet loss may cause decoding failures due to the dynamic link conditions of mobile wireless networks. In this paper, we propose a mobile-oriented video contents delivery method that utilizes network coding technology and P2P network architecture to reduce the service server load and the traffic of network. We simulate our proposed method with a QualNet simulator and compare it with traditional delivery methods.
