This study proposes a grade-based approach, which expeditiously maintains fairness in the network by encouraging the high contributed peers and altogether wiping out the free-riders. The Network Contribution Ratio determines the contribution of users globally. Besides, the proposed grading algorithm uses a point-based incentive mechanism which provides credit points to the users with respect to their grade and the transfer of users between each grade is instituted.}, journal = {American Journal of Engineering and Applied Sciences}, publisher = {Science Publications} }
