ABSTRACT
The emerging Peer-to-Peer (P2P) model has become a very powerful and attractive paradigm for developing Internet-scale systems for sharing resources, including files and documents. The distributed nature of these systems, where nodes are typically located across networks, inherently hinders the efficient retrieval of information. In this project, we consider the searching and retrieval of information that is scattered on peers of a network. Our approach builds on work in unstructured P2P systems and uses only local knowledge. The reason for using unstructured P2P systems is that ,they impose very small demands on individual nodes and can easily accommodate nodes of varying power.
