A two-stage queuing approach to support real-time QoS guarantee for multimedia services in TDMA wireless networks

This paper presents a two-stage queuing approach (TSQA) to improve the quality of service when real-time service in wireless channels [1]. In the first stage, the required delay, bandwidth, lose and input rate of different traffic classes are considered to allocate resource. In the second stage, the channel condition of each host is involved to achieve the optimal bandwidth utilization and fairness between hosts. Finally, from the mathematical analysis and simulation results, we confirm that the TSQA really support QoS requirements of real-time multimedia services in the TDAM wireless networks.
