Abstract

As mobile technology advances, more services on peer-to peer(P2P) systems in mobile ad-hoc networks are available in various forms. Recently double-layered P2P systems have been proposed to reduce the network traffic. Peers in a double-layered system are classified into super peers in the upper layer and sub-peers in the lower layer. One of the double-layered systems, called the MOB(MOBility) system, considers the mobility of peers and shows higher performance among other systems. But since the battery power of a mobile device is limited, the energy status of each peer should also be considered. In this paper, we propose a super-peer system considering both energy and mobility of peers when selecting super peers. The experiments have been performed on the network simulator NS-2 and the results showed that the proposed system improved the hit ratio about 5.70% over the MOB system, while maintaining more robust networks.
