An effective search technique in unstructured P2P networks

Efficient search in unstructured P2P networks has been extensively studied in the literature. And search in unstructured P2P networks shows promise to become an alternative to the state-of-the-art search engines. However, efficient search techniques for guaranteed location of shared resource in unstructured P2P networks are yet to be devised. The paper presents a simple but highly effective search method based on a hierarchical architecture in unstructured P2P networks. Index management for registered resource and routing algorithm for resource search are employed in the architecture. Simulation results show that the solution is efficient.
