Cross Layer Design for P2P Overlay Network over MANET

Peer-to-peer (p2p) network is an alternative of client/server system for sharing resources, e.g. files. P2P network is a robust, distributed and fault tolerant architecture. We consider the scenario of p2p network over MANET where all nodes are the members of p2p network and one of the node acts as p2p server which maintains the file list available to the nodes. The mobility of nodes constantly changes the file chunks availability in the peer which raises the demand for a comprehensive framework that can lucidly overlay p2p network on MANET. The p2p node is configured as server (peer). In p2p network, since nodes are peer they provide a large portion of shared files that can be accessed. A node decides to publish its files and update the server with the files. The server before sending the route request message, it forms a cluster. In this cluster one of the nodes is selected as cluster head based on maximum connectivity. We use an ad hoc on-demand routing protocol (AODV) through delay measurement to propose a p2p overlay network. In this work, we use simulation to determine the impact on the performance of the protocol. Simulation results show that the proposed protocol performs better.
