A Peer-to-Peer (P2P) network over a mobile ad hoc network is a combination that provides users with means to access dierent kinds of information anytime and anywhere. In this work we study the (re)configuration issue in this highly dynamic scenario. We presentthree algorithms designed to guide the (re)configuration of the P2P network in ad hoc scenario. These algorithms are especially concerned with the constraints of the environment presented: they aim to use the scarce resources of the network, such as energy and bandwidth, in an ecient way, improving performance and network lifetime. A simple Gnutella-like algorithm was also implemented, in order to be used as basis for comparison. All the algorithms were tested through simulations. The results show that the proposed algorithms achieved most of their goals, presenting a good cost-benefit relation.
