ABSTRACT
The challenge in unstructured p2p networks is designing an efficient Search Algorithm. Some typical search algorithms are random walk and flooding. Flooding in general covers many nodes but the drawback is it generates huge amount of query messages. Random walk generates only fewer amounts of query messages but takes long time to search. In this paper we propose a Proclamation Search (PS) algorithm for avoiding multiple hops in forwarding the query in unstructured Peer to peer network. Proclamation is publishing the synopsis of the contents a peer tends to share and properly distributed and cached by other peers. In this system, the nodes anticipatorily publish their contents, and selectively store interesting contents received from other peers. When there is a search request, a node can find the destination nodes by looking up its local publishing repository, and thus obtain one-hop search with moderate search cost. We analyze the performance of PS algorithm compared to other search algorithms based on search efficiency.
