Abstract Providing and guaranteeing Quality of Service requested by a user is an important and challenging task in telecommunication networks. Within ATM networks the negotiated service requirements have to be fulfilled using several methods of traffic management. WirelessATMintroduces a new dimension of complexity into these methods. While ATM applications in wireless ATMterminals request the same functionality and Quality of Service as in wired ATM terminals, the network characteristics like maximum transmission rate and error ratio differ. The methods for handling the user demands have to be adapted to this new environment. A radio cell of a cellular wireless or mobile ATM network corresponds to a virtual ATM multiplexer with an internal radio channel. For an analytic approach this multiplexer is modelled as a distributed queueing system. A central scheduler located in the base station determines the order of cell transmission and a MAC protocol organizes the realization of the transmission order on the radio channel. This paper focuses on the scheduling policy required to guarantee the requested Quality of Service especially for real-time VBR services. A scheduling strategy with dynamic priorities is developed and analysed using stochastic simulations.
