Fuzzy Optimal Decision for Network Bandwidth Allocation with Demand Uncertainty

In this paper, a fuzzy methodology is proposed to optimize network bandwidth allocation with demand uncertainty in communication networks (CNs). In this proposed methodology, uncertain traffic demands are first handled by a fuzzification way. Then a fuzzy optimization methodology is presented for network bandwidth allocation problem with the consideration of the trade-off between resource utilization and service performance in CNs. Accordingly, the optimal network bandwidth is allocated to obtain maximum network revenue in CNs. Finally, a numerical example is presented for purpose of illustration.
