Peer-to-Peer (P2P) networking technologies have gained popularity as a mechanism for users to share files without the need for centralized servers. A P2P network provides a scalable and fault-tolerant mechanism to locate nodes anywhere on a network without maintaining a large amount of routing state. The increasing availability of high bandwidth Internet connections and low-cost, commodity computers in people's homes has stimulated the use of resource sharing peer-to-peer networks. These systems employ scalable mechanisms that allow anyone to offer content and services to other system users. This allows for a variety of applications beyond simple file sharing. Examples include multicast systems, anonymous communications systems, and web caches. In this paper, the authors propose a reputation system for peer-to-peer network with free rider sensitivity.
