Query Routing Using Query Feedback and Similarity in Unstructured Peer-to-Peer Networks

In this paper, the authors propose a query based query routing approach for unstructured peer-to-peer network. They consider two parameters to be used to selectively route query in the network. The parameters are based on the recent past query and the similarity of the past query with the query to be routed. The objective of their approach is to have a low cost but effective routing approach in unstructured peer-to-peer networks. The authors approach also includes the method to take into account, the content of the query in which the query similarity is calculated as well as the query hits to determine connection reliability.
