| Abstract(in English) | Recently, the improved transmission speed and mobile device capability in wireless access networks enable people to use data/audio streaming/video streaming multicast services in large scale networks via their personal mobile devices. Peer-to-peer (P2P) architecture ensures scalability and robustness more easily and more economically than server-client architecture; as the number of nodes in a P2P network increases, the amount of workload per node decreases and lessens the impact of node failure. However, mobile users feel much larger psychological cost due to strict limitations on bandwidth, processing power, memory capacity, and battery life, and they want to minimize their contributions to these services. Therefore, the issue of how we can reduce this psychological cost remains. In this paper, we consider how effective a social networking service is as a platform for mobile P2P multicast. We model users' cooperative behaviors in mobile P2P multicast streaming, and propose a social-network based P2P streaming architecture for mobile networks. We also measured the psychological forwarding cost of real users in mobile P2P multicast streaming through an emulation experiment. The result shows that users cooperate with other user at a shorter social distance with lower psychological cost. We verify using multi-agent simulation that our social-network based mobile P2P multicast streaming improves service quality by reducing the psychological forwarding cost. |
