Optimal Resource Allocation in Complex Communication Networks

With the Internet highly developed, complex communication networks are now facing the dilemma of how to use limited resources to achieve the best communication performances. In this brief, we study the resource allocation from a more comprehensive perspective where both allocating the capacities of networks and distributing the rates of traffic flows are considered. We build an optimization problem to optimize the resource allocation and maximize the network utility at the same time. Moreover, we design an iterative algorithm to find the optimal solution. The convergence of this algorithm is supported by theoretical proofs and simulation results. Our work may give insights to the plan of resource allocation in future communication networks.
