Usability of Legacy P2P Multicast in Multihop Ad Hoc Networks: An Experimental Study

There has recently been an increasing interest in convergence of p2p and ad hoc network research. 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, the authors report their experience in running p2p applications in real multihop ad hoc network testbeds. Specifically, they used group-communication applications that require p2p systems made up of an overlay network and a p2p multicast protocol.
