Abstract
Centralized wireless networks with user arrivals and departures are considered. It is shown that variability in the service process increases the mean delay seen by users in such systems. This observation is used to develop a power control scheme that attains the right balance between service variability and service mean. For scheduling based physical layer schemes, the common understanding is that channel variability improves performance. It is argued here that channel variability can be undesirable when the channel is highly correlated in time.
