Actually p2p systems and multihop ad hoc networks share similar features such as self-organisation decentralisation self-healing and so forth. It is thus interesting to understand if p2p systems designed for the wired Internet are suitable also for ad hoc networks and if they are not in which direction they should be improved. In this paper we report our experience in running p2p applications in real multihop ad hoc network testbeds. Specifically we used group-communication applications that require p2p systems made up of an overlay network and a p2p multicast protocol. In this paper we present experimental results specifically related to the performance of a well-known p2p shared-tree multicast protocol Scribe . Our results show that such a solution is far from being efficient on ad hoc networks. We emphasize that the structured multicast approach is one of the main causes of inefficiency and suggest that stateless solutions could be preferable. Copyright 2007 A. Passarella and F. Delmastro.

INTRODUCTION The integration of p2p systems into multihop ad hoc networks is a very interesting and challenging topic that .
