Peer-to-peer networks are distributed computing infrastructures that can provide globally available network resources. Their size and complexity continue to increase and permit an almost ubiquitous availability of resources. Therefore, new discovery approaches are required and need to be highly flexible in order to cope with a dynamically changing environment. In this paper, a distributed agent-based approach for resource discovery in peer-to-peer network is proposed. This approach is based on the mobile agent paradigm and uses random walks to allow dynamic and adaptive resource discovery. We analyze this approach through three distributed resource discovery scenarios by NS2 simulator.
