A Search Algorithm Based on Referral Trust in Unstructured P2P Systems

Efficient search algorithm is one of the important issues in unstructured P2P systems. However, current search mechanisms are not efficient or scalable enough with the expansion of system. Gossip-based P2P techniques are reliable and scalable protocols for information dissemination. To this end, one search algorithm based on gossip algorithm with referral trust is proposed in our paper, in which peers can disseminate the query with low traffic and better efficiency.
