A P2P system consists of distributed nodes among which they share resources and more over the P2P system is decentralized and hence provides service without any central supervision. The major problem with P2P system is with locating the suitable resource because resources seemed to be dispersed over unstructured or structured overlay network and also the network formed is dynamic. Till date some of the solutions for locating resource have been provided. The most common technique for P2P resource discovery includes Flooding and Distributed Hash Tables (DHT). Query Flooding, a blind search algorithm where each node tries to forward the query to every one of its neighbors except the source from where the query was created. In DHT implementation, the hash table (key, value) pair does not support multiple keys for a single resource. This paper compares two resource discovery techniques Flooding Technique and the technique utilizing mobile agents to discover the resource in the network and the response time for the Query Hit between two methods and also ratio as well as difference in the number of query hits for both methods.
