Abstract :
An approximate analysis is derived of real-time voice and Markov modulated Poisson process (MMPP) video traffic over an enhanced time division multiple access with dynamic reservation (TDMA/DR) MAC protocol in a wireless ATM setting. This yields the mean delay and the delay distribution of such traffic under light loads (less than 60% of the total channel capacity). The reasonableness of the approximate analysis is verified by simulation. Numerical results indicate that the delay performances of voice and MMPP video traffic types are well within the respective delay tolerance for real-time services. The results lead to the conjecture that the enhanced TDMA/DR is a viable MAC protocol for handling real-time services in an integrated services wireless ATM system
