Peer-to-peer networks continue to gain popularity, but
the problem of locating suitable peers still remains
formidable. The lack of globally accepted standards and
protocols is another problem that further creates the
issue of a lack of global connectivity. This paper presents
a hybrid P2P infrastructure, called PSI, which uses Web
Services as registries to locate peers. We also formally
define the set of basic operations that are performed
during peer search to determine optimized connectivity.
Heuristics for locating peers are based on preference
values computed using historical data. The PSI model is
compared to other models with respect to suitability for
integrating a set of distributed and heterogeneous peers.
The mechanism for locating files depends only on
discovering and using Web Services. The greatest
advantage of this is the possibility of global connectivity.
The understanding gained by analysis and preliminary
implementation confirms that the model is highly
scalable.
