In this paper, we consider the call admission problem in cellular network with two classes of voice users. In the first part of paper, we introduce a two-threshold guard channel policy and study its limiting behavior under the stationary traffic. Then we give an algorithm for finding the optimal number of guard channels. In the second part of this paper, we give an algorithm, which minimizes th...

We present the proof of the optimality of Threshold Admission and Greedy Scheduling (TAGS) policy under both average and deterministic settings. We first show that EDF-LMO always maintains low cost sources charging plan feasible. Then under the stochastic setting, the admission problem is formulated as a stochastic dynamic programming problem and the optimality of Threshold Admission policy is ...

This paper employs the threshold cointegration methodology to assess long- and short-run dynamics of asymmetric adjustment between economic policy uncertainty (EPU) China-India, China-Japan, China-Korea, India-Japan, India-Korea, Japan-Korea pairs using monthly EPU data ranging from January 1997 April 2020. The relationship is examined in terms Engle-Granger cointegrations. findings provide evi...
