This study introduces a cluster-based search for peer-to-peer networks, improving efficiency by grouping similar peers. This method enhances search speed and network resilience against failures.

Area of Science:

  • Computer Science
  • Network Engineering
  • Distributed Systems

Background:

  • Peer-to-peer (P2P) networks facilitate decentralized resource sharing.
  • Data distribution in P2P networks exhibits inherent structural features.
  • Efficient information retrieval remains a challenge in large-scale P2P systems.

Purpose of the Study:

  • To propose a novel cluster-based search scheme for P2P networks.
  • To enhance search efficiency and query routing.
  • To maintain network resilience despite peer failures.

Main Methods:

  • Developed an algorithm for clustering peers based on shared interests.
  • Implemented a query forwarding mechanism prioritizing intra-cluster communication.
  • Evaluated the scheme's performance in terms of search speed and robustness.
