Built on the basis of the classified subscribe station (SS) priorities, a policy-based call admission control scheme is proposed to maximize the system bandwidth throughput and decrease the network delay at the base station(BS) in IEEE 802.16d system. In the simulation, we use throughput comparison and the delay increasing trend as the evaluating criterions. The simulation results show that our proposed...
In the paper, we propose a dynamic hierarchical call admission control mechanism in IEEE 802.16d WiMAX system. The mechanism is built upon hierarchical user nodes priorities and service classes priorities. And it uses a dynamic bandwidth algorithm to maximize the bandwidth allocation efficiently at the base station. In this paper, we use average polling delay and scheduling efficiency as the performance...
