ATM 기반 IMT-2000망에서 QoS에 기반한 대역폭 관리기법

QoS oriented bandwidth management scheme on the ATM based IMT-2000 networks

In this paper, we propose bandwidth management scheme to efficiently guarantee the QoS of various services on ATM based IMT-2000 networks. The proposed bandwidth management scheme consists of the call admission control to reduce a handoff failure probability and the scheduling scheme to efficiently allocate a time slot based on the QoS requirements in wireless links. The simulation results show that the proposed bandwidth scheme has better performance than the previous works in terms of the handoff failure probability and packet delay time.
