Performance evaluation of a wireless ATM switch using priority-based dynamic capacity allocation scheme

Performance analysis of a wireless ATM switching system using priority-based dynamic capacity allocation is presented. The system provides connectivity between a number of clusters of wireless ATM remote terminals. The scheduling of ATM cell transmission at each lint with TDMA frame is based on a priority scheme with priority given to real-time traffic over non-real-time traffic. Both types of traffic arriving at the downstream links are approximated by a 2-state Markov-modulated Poisson process (MMPP) in order to obtain analytical results. Illustrative results for two different traffic loads and at the output of 4/spl times/4 switch are discussed.
