Optimal cyclic service of the centralized broadband wireless networks with k-limited discipline

In this paper, a cyclic service system enabling an adequate description of the control mechanism of the centralized broadband wireless networks with k-limited discipline is presented. An arrival rate prediction method combined with the ordinal optimization (OO) theory-based algorithm is proposed to find a good enough k-limited discipline for the cyclic service system so as to achieve the real-time application. First, we employ the Box–Jenkins method for predicting the arrival rate every Δt period, which is the computation time for executing the OO theory-based algorithm on a base station. Then, the predicted arrival rates will serve as the current arrival rates in the OO theory-based algorithm. We have tested the proposed method by comparing with the cases of using the actual arrival rate at t + Δt, which is considered as the ideal case, and the arrival rate at t, which is considered as the case without prediction, in the OO theory-based algorithm. The test results show that the performance of the case without prediction is 15.72% worse than the ideal case, while the proposed method achieves a performance of only 3.94% worse than the ideal case.
