Comparison of optimal buffer allocation in flow lines under installation buffer, echelon buffer, and CONWIP policies
(2020)We compare the optimal buffer allocation of a manufacturing flow line operating under three different production control policies: installation buffer (IB), echelon buffer (EB), and CONWIP (CW). IB is the conventional ... -
Cross-layer energy-aware topology control through Simulated Annealing for WSNs
(2016)In this paper, we optimize the energy consumption and node placements of a wireless sensor network (WSN) using Simulated Annealing (SA). We propose an energy-aware optimization of the power control, the packet transmission ... -
Distributed resource allocation algorithms for peer-to-peer networks
(2008)In peer-to-peer networks, each peer plays the role of client and server. As server, it receives content requests made by other peers and needs to decide on what basis and to what extent it will satisfy these requests by ... -
Energy-aware joint power, packet and topology optimization by simulated annealing for WSNs
(2013)Energy-aware connectivity in wireless sensor networks (WSNs) can increase their network lifetime. This can be achieved by optimizing the power control, a particular communication mechanism and the topology control. To this ... -
Forming District Metered Areas in a Water Distribution Network Using Genetic Algorithms
(2016)Dividing a water distribution network into District Metered Areas (DMAs) is the first vital step towards water loss management. It is a multivariate problem. Techniques based on Genetic Algorithms is a proven way to provide ... -
Impacts of autonomous on-demand mobility service: A simulation experiment in the City of Athens
(2022)High-capacity Connected and Autonomous Vehicles (CAVs) are expected to be extensively utilized by on-demand services. This paper aims to assess the impacts of large-scale autonomous on-demand mobility services on traffic, ... -
Lifetime maximization in wireless sensor networks with an estimation mission
(2009)We study the problem of maximum lifetime in wireless sensor networks that are entitled with the task of estimating an unknown parameter or process. Sensors take measurements and transfer them in multi-hop fashion to a ... -
Measurement aggregation and routing techniques for energy-efficient estimation in wireless sensor networks
(2010)Wireless sensor networks are fundamentally different from other wireless networks due to energy constraints and spatial correlation among sensor measurements. Mechanisms that efficiently compress and transport sensor data ... -
Medium-Term Unit Commitment in a pool market
(2011)We consider a mandatory pool, based to the one established in the Greek electricity market, in which the unit commitment and the scheduling of energy and reserves are the solution of Day-Ahead Scheduling (DAS), an optimization ... -
A methodology for the estimation of the effective yield function of isotropic composites
(2016)In this work we derive a general model for N-phase isotropic, incompressible, rate-independent elasto-plastic materials at finite strains. The model is based on the nonlinear homogenization variational (or modified secant) ... -
Multi-Commodity Traffic Signal Control and Routing With Connected Vehicles
(2022)A real-time traffic management policy that integrates traffic signal control and multi-commodity routing of connected vehicles in networks with multiple destinations is developed. The proposed policy is based on a ... -
Optimal jamming attack strategies and network defense policies in wireless sensor networks
(2010)We consider a scenario where a sophisticated jammer jams an area in which a single-channel random-access-based wireless sensor network operates. The jammer controls the probability of jamming and the transmission range in ... -
Optimal sensor placement for reliable virtual sensing using modal expansion and information theory
(2021)A framework for optimal sensor placement (OSP) for virtual sensing using the modal expansion technique and taking into account uncertainties is presented based on information and utility theory. The framework is developed ... -
The SDN Control Plane Challenge for Minimum Control traffic: Distributed or Centralized?
(2019)Software Defined Networking (SDN) decouples the control and data planes and moves the control logic to the SDN controllers. The traffic in the control plane is either related to the interconnection of the controllers or ... -
Topology control with coverage and lifetime optimization of wireless sensor networks with unequal energy distribution
(2017)In this work, we use an unequal energy distribution algorithm, with which we succeed to extend network lifetime. In the sequel, we, we provide the best effort coverage by arranging the nodes using topology control principles. ...
