Abstract:

In this paper, we study the joint problem of real-time user association, traffic routing and Virtual Network Function (VNF) placement towards maximizing the mobile network’s energy efficiency and user acceptance ratio. The studied problem is formulated as a Mixed Integer Linear Program (MILP), under various computational, capacity, and flow conservation constraints, while also meeting the Service Function Chain (SFC), throughput and delay requirements of each service request. In addition to the optimal solution of the MILP problem, an efficient low computational complexity heuristic (named as ONE) is also developed and evaluated via simulations. The proposed solutions are shown to significantly outperform the State-of-Art (SoA) in terms of energy efficiency, with ONE achieving up to 89% of the optimal energy efficiency value with up to 9 0% lower computational time even under heavy user traffic load scenarios.
