Over the years of the emergence of peer-to-peer systems a phenomenon named 'Free Riding' has affected its performance and become a serious threat to be resolved. Free riding phenomenon was first felt in the study of Gnutella. As the number of free riders increases, the performance of the overall system decreases as free riders use resources without giving anything to the system. To solve the problem of free riding the authors have developed an Extended Point Based Incentive Mechanism (EPBIM) through which the users are given some incentives to share some files into the system.
