(English Abstract)
As the mobile technology advances, various mobile peer-to-peer (P2P) systems have been developed. Since mobile devices have limited energy capacity and communication range, efficient use of the energy and reliability of network are indispensable for mobile P2P systems. The double layered mobile P2P system using super peers use less quantity of message to find file than the single layered mobile P2P system. However, super peers consume lots of energy since sub peers send request message to their super peers continuously. As super peers manage their sub peers information, super peers are central role of communication. If super peers cannot communicate with their sub peers due to movement of super peers, it would raise network reliability problems. In this paper, the proposed system that considers remaining energy and speed of peers improves energy efficiency and network reliability. Also we propose the routing scheme that selects peers with sufficient amount of energy and steady speed whenever peers communicate with each other. The experimental results show the proposed system outperforms a typical double layered mobile P2P system using super peers in terms of energy efficiency and network reliability.
