Abstract EN
Efficient searching for resources has become a challenging task with less network bandwidth consumption in unstructured peer-to-peer (P2P) networks.
Heuristic search mechanism is an effective method which depends on the previous searches to guide future ones.
In the proposed methods, searching for high-repetition resources is more effective.
However, the performances of the searches for nonrepetition or low-repetition or rare resources need to be improved.
As for this problem, considering the similarity between social networks and unstructured P2P networks, we present a credibility search algorithm based on different queries according to the trust production principle in sociology and psychology.
In this method, queries are divided into familiar queries and unfamiliar queries.
For different queries, we adopt different ways to get the credibility of node to its each neighbor.
And then queries should be forwarded by the neighbor nodes with higher credibility.
Experimental results show that our method can improve query hit rate and reduce search delay with low bandwidth consumption in three different network topologies under static and dynamic network environments.
