Nearly-optimal scheduling of users with Markovian time-varying transmission rates
(2016-01-01)
We address the problem of developing a well-performing and implementable scheduler of users with wireless connections to the central controller, which arise in areas such as mobile data networks, heterogeneous networks, ...
Generalized restless bandits and the knapsack problem for perishable inventories
(2014-12-31)
In this paper we introduce the knapsack problem for perishable inventories concerning the optimal dynamic allocation of a collection of products to a limited knapsack. The motivation for designing such a problem comes from ...
Optimal planning of slow-ramping power production in energy systems with renewables forecasts and limited storage
(2014-12-31)
We address the cost-efficient operation of an energy production system under renewables uncertainty. We develop an MDP model for an idealized system with the following features: (1) perfectly predictable power demand, (2) ...
Scheduling of users with Markovian time-varying transmission rates
(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
(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 ...
CCN interest forwarding strategy as Multi-Armed Bandit model with delays
(2012-12-31)
We consider Content Centric Network (CCN) interest forwarding problem as a Multi-Armed Bandit (MAB) problem with delays. We investigate the transient behaviour of the ε-greedy, tuned ε-greedy and Upper Confidence Bound ...
Optimal congestion control of TCP flows for internet routers
(2012-12-31)
In this work 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 TCP source and a bottleneck queue with ...
Optimal anticipative congestion control of flows with time-varying input stream
(2012-12-31)
This paper is concerned with a new type of congestion control method that we call anticipative congestion control, which exploits probabilistic information available at a network node about congestion at other nodes. ...
Opportunistic schedulers for optimal scheduling of flows in wireless systems with ARQ feedback
(2012-12-31)
In this paper we study three opportunistic schedulers for the problem of optimal multi-class flow-level scheduling in wireless downlink and uplink systems. For user channels we employ the Gilbert-Elliot model of good and ...
A nearly-optimal index rule for scheduling of users with abandonment
(2011-12-31)
We analyze a comprehensive model for multi-class job scheduling accounting for user abandonment, with the objective of minimizing the total discounted or time-average sum of linear holding costs and abandonment penalties. ...
