The Parallel Rings Topology in Semantic Peer- to-Peer Networks

The Peer-to-Peer networks are very popular in decentralized information retrieval; however, decreasing the network traffic generated by the broadcast messages is still an open question. There are some semantic approaches that implements metadatabased routing or node selection as a new layer on existing protocols. However, the high connectedness of such networks could decrease the number of successful queries. In this paper we present a solution for the clustering of semantic peer-to-peer networks by altering a semantic protocol to construct a topology that better serves for the intelligent neighbor selection. The topology eliminates the counterproductive links from the network, hence the number of hops of the messages required for a succesful query can be decreased and the communication costs can be kept low.
