Peer-to-peer networks continue to gain popularity, butthe problem of locating suitable peers still remainsformidable.The lack of globally accepted standards andprotocols is another problem that further creates theissue of a lack of global connectivity.This paper presentsa hybrid P2P infrastructure, called PSI, which uses WebServices as registries to locate peers.We also formallydefine the set of basic operations that are performedduring peer search to determine optimized connectivity.Heuristics for locating peers are based on preferencevalues computed using historical data.The PSI model iscompared to other models with respect to suitability forintegrating a set of distributed and heterogeneous peers.The mechanism for locating files depends only ondiscovering and using Web Services.The greatestadvantage of this is the possibility of global connectivity.The understanding gained by analysis and preliminaryimplementation confirms that the model is highlyscalable.
