| Since modern telecommunication systems are nearly all digital systems, the use of discrete-time queueing models is investigated for the performance analysis of some of these systems. Several discrete-time single server queues are studied and the relationships among the discrete-time queues and the continuous-time queues are also discussed.; To analyze modern multiple traffic wireless systems, the speech interpolation systems are first analyzed. Queueing models are developed for the speech interpolation system with loss, the speech interpolation system with delay and the speech interpolation system with delay and loss. Then the voice/data TDMA system are studied by the use of the developed modeling techniques. The queueing model for this system can be obtained by integrating the data traffic into the speech interpolation system with loss. Finally, the video traffic in wireless mobile systems and the multimedia TDMA system with voice traffic, data traffic and video traffic are investigated. The mean system delays are presented as measures of performance. |
