Extension of multimedia services and applications offered by ATM networks to wireless and mobile users has
captured a lot of recent research attention. Research prototyping of wireless ATM networks is currently underway
at many leading research and academic institutions. Various architectures have been proposed depending on the
intended application domain. Successful implementation of wireless connectivity to ATM services is significantly
dependent on the medium access control (MAC) protocol, which has to provide support for multimedia traffic and
for quality­of­service (QoS) guarantees. The objective of this paper is to investigate the comparative performance
of a set of access protocols, proposed earlier in the literature, with more realistic source traffic models. Data traffic
is modeled with self­similar (fractal) behavior. Voice traffic is modeled by a slow speech activity detector (SAD).
Video traffic is modeled as a H.261 video teleconference, where the number of ATM cells per video frame is
