Abstract: The delay jitter performance of voice traffic, modeled using an exponential On/Off source, in a cellular wireless ATM network is analyzed. The uplink MAC (Medium Access Control) protocol is implemented by a P-TDMA/DR (Prioritized Time Division Multiple Access with Dynamic Reservation) MAC protocol. Voice, compressed video and data are used as test traffic. The delay jitter (or cell delay variation) of an exponential On/Off voice is evaluated using approximate analysis and computer simulation. Numerical results indicate that, with very high probability of 0.92 (simulation) or 0.96 (analysis), the voice delay jitter is practically zero and, with very low probability, it is at other values. 99.1% of the voice delay jitter are within ±10 TDMA frame intervals. This shows that the voice delay jitter is well-behaved due to the excellent design of the P-TDMA/DR MAC protocol for voice traffic.
