In Peer-To-Peer (P2P) file sharing systems, many autonomous peers without pre-existing information share files with each other. Due to their open environment and distributed structure, these systems are vulnerable to the significant impact from selfish and un-trusted nodes. This paper focuses on implementing a congestion control method on P2P systems for efficient file sharing. The system uses a congestion detection algorithm to detect and eliminate the congested node in the P2P network. Further this system alerts all the other peers about the detected congestion node for reducing the chances of further transmission performance degradation.
