Abstract
As the number of mobile device users increases, many researches on pee-to-peer (P2P) systems in mobile environments have been carried out. In this paper, we propose two mobile P2P systems that have double-layered topology. In these systems, peers are classified into two groups, super peers and sub-peers and a super peer has zero or more sub-peers. In the proposed systems, when a peer wants to search a file, there is no need of multi-broadcasting because each super peer maintains the appropriate information of its sub-peers and because a pair of super peers communicate each other along only the route from one super peer to the other via some sub-peers since there may be no direct connection between a pair of super peers. The experimental results show that the proposed systems outperform a typical mobile P2P system in terms of the average number of messages to find target files while maintaining the same search accuracy.
