The leaky-bucket regulator has several potential roles in the operation of future transport networks; among them, the bounding of possible source trajectories in implementations of worst-case approaches to network design. It seems plausible that there will be applications whose specific traffic characteristics are known a priori neither to the user nor to the network; in such cases, a recursive algorithm for setting the leaky-bucket parameters may prove useful. We devise such an algorithm here. The leaky-bucket parameters are computed recursively over a limited period of observation of the source behavior. We provide an explicit characterization of the dynamics of the estimator, and the... 

In this paper, we analyze the effect of applying leaky bucket as a well known traffic shaper on data users in a variable spreading gain CDMA (VSG-CDMA) uplink wireless cellular network. To this end, we model the effect of leaky bucket mechanism on a typical data user, with a closed product form queueing network. Each node in this queueing network corresponds to a specific processing gain or equivalently transmission rate and power. By solving such a queueing network we obtain the steady state probability with which a typical data user will exist at each node. By aggregating the effects of all data users we compute the mean and variance of interference and obtain the throughput and average...
