An approach to minimize Topology Mismatch Problem in similarity -Aware Heterogeneous P2P Networks

The primary properties of the existing large scale peer-to-peer system include very high heterogeneity and dynamic nature of the participating peers in the network. Properties of peers such as peer session length, accessible bandwidth, storage space are highly varied with small set of peers controlling large part of the total system resources which results in low performance of the system. The nature of peers randomly joining and leaving the network causes the topology mismatch which drastically affects the network traffic. By taking along the advantages of similarity-aware overlays, the proposed system tries to reduce the effect of heterogeneous peers in unstructured peer-to-peer networks. The system is evaluated with proper simulations and the results show improvement in the total system capability. KeywordsP2P, Unstructured, Overlays, Heterogeneity, Gnutella
