Abstract:

Among various searching techniques,semantic-based searching has drawn significant attention recently.In this paper,we propose a novel and efficient search mechanism SKIP （search with K-Iteration preference）for P2P networks based on semantic group.In SKIP system,the most relevant part of the target nodes will be preferentially chosen to forward the query and that is called SKIP.Our analysis and simulation results show that the SKIP scheme provides a low overhead on topology maintenance that can be effectively used in P2P searching.Compared with the current semantic-based searching mechanism,we show that the SKIP scheme can outperform in terms of higher precision and lower search cost.

Key words: K-Iteration, preference, P2P network
