Abstract

The utilization of peer-to-peer (P2P) overlay networks on mobile ad hoc networks (MANET) introduces new services and possibilities such as content based routing and location based services (LBS). A simple layering of both networks is inefficient and does not scale well because the virtual P2P overlay network does not match the frequently changing physical network topology of the MANET. The mobile peer-to-peer (MPP) protocol stack offers a very promising concept by introducing a cross-layer communication channel between the physical network layer and the virtual P2P network layer. This reduces significantly the messaging overhead and increases the search success rate, as we can prove in this work. Therefore, we describe an implementation of the MPP protocol stack in the Network Simulator 2 (ns-2). With this implementation, we prove the significant performance improvements which can be achieved with MPP, to allow P2P networking in mobile ad hoc environments.
