Access and control in a cellular wireless ATM network
T.C. Wong, J.W. Mark, K.C. Chua · 2002
We consider a system configuration consisting of both an uplink MAC (medium access control) protocol and a UPC (usage parameter control) at the base station for supporting heterogeneous services. The MAC is implemented by an enhanced TDMA/DR (time division multiple access with dynamic reservation) MAC protocol while the UPC is implemented by a leaky bucket device. Voice, compressed video and data are used as test traffic. The performance metrics are delay and cell loss. Numerical results based on approximate analysis and simulation are used to draw conclusions regarding the size of input buffers of the leaky bucket needed to yield a prescribed packet loss rate.
