A modeling framework for optimizing the flowlevel scheduling with timevarying channels
(20101231)We introduce a comprehensive modeling framework for the problem of scheduling a finite number of finitelength jobs where the available service rate is timevarying. The main motivation comes from wireless data networks ... 
A nearlyoptimal index rule for scheduling of users with abandonment
(20111231)We analyze a comprehensive model for multiclass job scheduling accounting for user abandonment, with the objective of minimizing the total discounted or timeaverage sum of linear holding costs and abandonment penalties. ... 
An Analysis of CoalitionCompetition Pricing Strategies for MultiOperator Mobile Traffic Offloading using Biobjective Heuristics
(2017)In a competitive market relationships between telecommuni cations operators serving simultaneously over a certain geographical area are diverse and motivated by very different business strategies and goals. Such relationships ... 
Asymptotically optimal parallel resource assignment with interference
(20101231)Motivated by scheduling in cellular wireless networks and resource allocation in computer systems, we study a service facility with two classes of users having heterogeneous service requirement distributions. The aggregate ... 
CCN interest forwarding strategy as MultiArmed Bandit model with delays
(20121231)We consider Content Centric Network (CCN) interest forwarding problem as a MultiArmed Bandit (MAB) problem with delays. We investigate the transient behaviour of the εgreedy, tuned εgreedy and Upper Confidence Bound ... 
Closed queueing networks under congestion: Nonbottleneck independence and bottleneck convergence
(20131231)We analyze the behavior of closed multiclass productform 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 ... 
Community Detection in Networks using Bioinspired Optimization: Latest Developments, New Results and Perspectives with a Selection of Recent MetaHeuristics
(2019)Detecting groups within a set of interconnected nodes is a widely addressed prob lem that can model a diversity of applications. Unfortunately, detecting the opti mal partition of a network is a computationally demanding ... 
Comparative study of pheromone control heuristics in ACO algorithms for solving RCPSP problems
(201711)Constraint Satisfaction Problems (CSP) belong to a kind of traditional NPhard problems with a high impact on both research and industrial domains. The goal of these problems is to find a feasible assignment for a group ... 
Competition yields efficiency in load balancing games
(20111231)We study a nonatomic congestion game with N parallel links, with each link under the control of a profit maximizing provider. Within this 'load balancing game', each provider has the freedom to set a price, or toll, for ... 
Congestion control of TCP flows in Internet routers by means of index policy
(20131231)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 ... 
Convergence of trajectories and optimal buffer sizing for AIMD congestion control
(20101231)We study the interaction between the AIMD (Additive Increase Multiplicative Decrease) multisocket congestion control and a bottleneck router with Drop Tail buffer. We consider the problem in the framework of deterministic ... 
Convergence of trajectories and optimal buffer sizing for MIMD congestion control
(20101231)We study the interaction between the MIMD (Multiplicative Increase Multiplicative Decrease) congestion control and a bottleneck router with Drop Tail buffer. We consider the problem in the framework of deterministic hybrid ... 
Costefficient deployment of multihop wireless networks over disaster areas using multiobjective metaheuristics
(201707)Nowadays there is a global concern with the growing frequency and magnitude of natural disasters, many of them associated with climate change at a global scale. When tackled during a stringent economic era, the allocation ... 
Costefficient Selective Network Caching in LargeArea Vehicular Networks using Multiobjective Heuristics
(2017)In the last decade the interest around network caching tech niques has augmented notably for alleviating the evergrowing demand of resources by end users in mobile networks. This gained momentum stems from the fact that ... 
Decentralized proportional load balancing
(20160101)Load balancing is a powerful technique commonly used in communication and computer networks to improve system performance, robustness and fairness. In this paper, we consider a general model capturing the performance of ... 
Detection of nontechnical losses in smart meter data based on load curve profiling and time series analysis
(201706)The advent and progressive deployment of the socalled Smart Grid has unleashed a profitable portfolio of new possibilities for an efficient management of the lowvoltage distribution network supported by the introduction ... 
Efficiency of simulation in monotone hyperstable queueing networks
(20141231)We consider Jackson queueing networks with finite buffer constraints (JQN) and analyze the efficiency of sampling from their stationary distribution. In the context of exact sampling, the monotonicity structure of JQNs ... 
Energyaware capacity scaling in virtualized environments with performance guarantees
(20111231)We investigate the tradeoff between performance and power consumption in servers hosting virtual machines running IT services. The performance behavior of such servers is modeled through Generalized Processor Sharing (GPS) ... 
Ergodic transition in a simple model of the continuous double auction
(20141231)We study a phenomenological model for the continuous double auction, whose aggregate order process is equivalent to two independent M/M/1 queues. The continuous double auction defines a continuoustime random walk for trade ...
