A Peer-to-Peer self-organizing scheme for multiparty session

In Peer-to-Peer (P2P) networks, nodes (peers) have symmetric roles. They are useful in a wide range of application scenarios, especially in relation to the Internet, such as file sharing and data retrieval. This work investigates the prospects for using self-organizing P2P networking in multiparty session applications such as presence and audio/video conferencing. The proposed architecture relies on a clustering structure that composes an overlay over the network layer, in which cluster-heads are automatically enabled and disabled when the network grows and shrinks. A bandwidth usage-balancing scheme equilibrates bandwidth usage among cluster-heads according to their respective capacities. We demonstrate the self-organizing network growth and shrinkage through simulations.
