Resource Discovery Mechanisms for Peer-to-Peer Systems

Abstract

One of the most important problems for Peer-topeer (P2P) system is searching and retrieving the correct information based on the query request. In this paper, we will discuss several existing resource discovery mechanisms that have been widely implemented in P2P networks. Thus, we are classifying the P2P systems based on their resource discovery mechanisms. Consequently, we will present taxonomy for P2P resource discovery as a hierarchy based on our classification. The classification is done for seek out generalities amongst resource discovery mechanisms. We also specifically highlight on issues related to challenges for providing the resource discovery mechanism to the P2P networks. Issues related to matrix for measuring the cost and benefit for choosing the right resource discovery mechanism for a P2P system will conclude the paper.
