Protecting peer-to-peer networks from the denial of service attacks

The purpose of this paper is to reduce the Denial of Service (DoS) attacks on peer-to-peer networks by hiding the position of the file and to prove the effectiveness through the fuzzy logic. In general to protect the files in the serverless distributed file systems from the attacker, we have to maintain large number of copies of the original file that leads to storage overhead. This paper presents location hiding approach that needs only minimum number of copies of file. The location hiding approach uses Location Key and routing guard. We use chord protocol to implement peer-to-peer system. We use fuzzy logic to develop a graph that provides better performance of the Location hiding approach.
