Data In P 2 P Systems

The term peer-to-peer refers to a class of systems and applications that employ distributed resources to perform a critical function in a decentralized manner. The main challenge in P2P computing is to design and implement a robust and scalable distributed system composed of inexpensive, individually unreliable computers in unrelated administrative domains. In this paper we discuss about the goals, characteristics and data sharing problems that may exist in P2P systems. Then we are doing a case study of ORION, a file sharing system in MANET P2P systems.
