Self-Configuration Protocols for Small-Scale P2P Networks

This paper proposes several protocols, including the random, egoist, altruist, greedy and optimizer protocols, for individual peers to self-configure the P2P overlay network. Our simulation studies show that the optimizer protocol for the P2P overlay network self-configuration tries to minimize the difference between the physical network distance and the logical network distance of two nodes by creating a virtual link along the network path having the shortest physical distance in the network, is superior to other protocols in terms of the network diameter and average node eccentricity
