Abstract |
This paper proposes a modified mathematical model for revenue management in terms of uplink admission control. The solution approach to the model is Lagrangean relaxation. Performance analysis is based on voice activity factor (VAF), where 9 base stations, 50 existing mobile users are given. In addition, new mobile users are generated in Poisson arrival process (λ=100) on 500 test cases. Computational results illustrate that no matter which value of VAF is given; the proposed primal algorithm outperforms other heuristics on solution optimality, blocking rate, as well as revenue contribution. |
