A Hybrid Searching Scheme in Unstructured P2P Networks

The existing searching schemes in Peer-to-Peer (P2P) networks are either forwarding-based or non-forwarding based. In forwarding-based schemes, queries are forwarded from the querying source to the query destination nodes. These schemes offer low state maintenance. However, querying sources do not entirely have control over query processing. In non-forwarding based methods, queries are not forwarded, and the querying source directly probes its neighbors for the desired files. Non-forwarding searching provides querying sources flexible control over the searching process at the cost of high state maintenance. In this paper, we seek to combine the powers of both forwarding and non-forwarding searching schemes. We propose an approach where the querying source directly probes its own extended neighbors and forwards the query to a subset of its extended neighbors and guides these neighbors to probe their own extended neighbors on its behalf. Our approach can adapt query processing to the ...
