Scheduling of users with Markovian time-varying transmission rates
(Performance Evaluation Review, 2013-12-31)
We address the problem of developing a well-performing and implementable scheduler of users with wireless connection to the base station. The main feature of such real-life systems is that the quality conditions of the ...
Congestion control of TCP flows in Internet routers by means of index policy
(Computer Networks, 2013-12-31)
In this paper we address the problem of fast and fair transmission of flows in a router, which is a fundamental issue in networks like the Internet. We model the interaction between a source using the Transmission Control ...
Closed queueing networks under congestion: Nonbottleneck independence and bottleneck convergence
(Mathematics of Operations Research, 2013-12-31)
We analyze the behavior of closed multiclass product-form queueing networks when the number of customers grows to infinity and remains proportionate on each route (or class). First, we focus on the stationary behavior and ...
Heavy-traffic revenue maximization in parallel multiclass queues
(Performance Evaluation, 2013-12-31)
Motivated by revenue maximization in server farms with admission control, we investigate the optimal scheduling in parallel processor-sharing queues. Incoming customers are distinguished in multiple classes and we define ...
