In Peer-to-Peer (P2P) file-sharing systems, cooperative file-caching improves the file availability. Users have different degree of cooperativity in caching files and they are in different surrounding environments arising from the topological structure of the P2P network. In this paper, with evolutionary game theory, we experimentally evaluate the performance of P2P file sharing systems in such heterogeneous environments. Simulation results show that the environmental heterogeneity contributes to conservation of the file availability and stability of the system.
