Utility Maximization for Fair Bandwidth Allocation in Peer-to-Peer File-Sharing Networks
In P2P networks fairness is very important since it fosters an incentive to the peers to offer resources to the networks.In this paper,we consider fair resource allocation in P2P file-sharing networks and develop a coupled utility maximization model with different fairness concepts.We provide a meaningful interpretation of the problem of maximizing social welfare and its sub-problems from an economic point of view.In order to solve the coupled optimization problem,we apply a modified successive approximation method and present a distributed primal-dual resource allocation scheme to solve the approximation problem.Then,we evaluate the performance of the proposed algorithm through theoretical analysis and numerical examples.Simulation results validate that the algorithm can achieve the global optimum within reasonable iterations.
