Abstract EN
This paper considers a joint optimal design of admission control and resource allocation for multimedia services delivery in high-speed railway (HSR) wireless networks.
A stochastic network optimization problem is formulated which aims at maximizing the system utility while stabilizing all transmission queues under the average power constraint.
By introducing virtual queues, the original problem is equivalently transformed into a queue stability problem, which can be naturally decomposed into three separate subproblems: utility maximization, admission control, and resource allocation.
A threshold-based admission control strategy is proposed for the admission control subproblem.
And a distributed resource allocation scheme is developed for the mixed-integer resource allocation subproblem with guaranteed global optimality.
Then a dynamic admission control and resource allocation algorithm is proposed, which is suitable for distributed implementation.
Finally, the performance of the proposed algorithm is evaluated by theoretical analysis and numerical simulations under realistic conditions of HSR wireless networks.
