Exploiting task-based parallelism in Bayesian Uncertainty Quantification
(2015)We introduce a task-parallel framework for non-intrusive Bayesian Uncertainty Quantification and Propagation of complex and computationally demanding physical models on massively parallel computing architectures. The ... -
Gathering of robots in a grid with mobile faults
(2019)The gathering of two or more agents in a graph is an important problem in the area of distributed computing and has been extensively studied especially for the fault free scenario. In this paper we consider the mobile ... -
Improved genetic algorithms and list scheduling techniques for independent task scheduling in distributed systems
(2007)Given a set of tasks with certain characteristics, e.g., data size, estimated execution time and a set of processing nodes with their own parameters, the goal of task scheduling is to allocate tasks at nodes so that the ... -
Investigating the replica transfer scheduling problem
(2006)The Replica Placement Problem (RPP) aims at selecting the nodes for duplicating data objects in order to optimize their access. Even though a lot of work already exists on RPP, the issue of implementing the resulting ... -
Lightweight jammer localization in wireless networks: System design and implementation
(2009)Jamming attacks have become prevalent during the last few years, due to the shared nature and the open access to the wireless medium. Finding the location of a jamming device is of great importance for restoring normal ... -
Mobile healthcare information management utilizing Cloud Computing and Android OS
(2010)Cloud Computing provides functionality for managing information data in a distributed, ubiquitous and pervasive manner supporting several platforms, systems and applications. This work presents the implementation of a ... -
Monitoring supply current thresholds for smart device's security enhancement
(2019)The rapid growth of connected devices and the sensitive data they generate poses a significant challenge for manufacturers seeking to comprehensively protect their devices from attack. This paper presents a study and its ... -
NITOS testbed: A cloud based wireless experimentation facility
(2014)The NITOS wireless testbed, is one of the main building blocks in the wireless testbed experimentation, offered by the FIRE community, and a core Fed4Fire partner. Its main focus is on wireless accessed technologies and ... -
OmniStore: Automating data management in a personal system comprising several portable devices
(2007)The ever growing amount of data generated and consumed on the move using portable devices gives rise to serious data management issues. The fact that each person may own and is likely to carry several such devices further ... -
On green scheduling for desktop grids
(2018)Task scheduling is of paramount importance in a desktop grid environment. Earlier works in the area focused on issues such as: meeting task deadlines, minimizing make-span, monitoring and checkpointing for progress, malicious ... -
On the information diffusion between web-based social networks
(2015)The topic of Information diffusion has been in the centre of sociology interest for many years. Even before the rise of Online Social Networks (OSNs), social ties and the way the information flows have been studied in ... -
On the optimal processor assignment for computing the steady state kalman filter in parallel and distributed systems
(2017)Kalman filters have many practical applications in various fields such as sensor networks, image and video processing. Therefore, their fast computation is of paramount importance. In this paper distributed implementations ... -
Online live VM migration algorithms to minimize total migration time and downtime
(2019)Virtual machine (VM) migration is a widely used technique in cloud computing systems to increase reliability. There are also many other reasons that a VM is migrated during its lifetime, such as reducing energy consumption, ... -
Providing support for integrated scientific computing: Metacomputing meets the grid and the semantic web
(2005)In this paper, we present an integrated system architecture for metacomputing on top of distributed scientific resources via semantic-driven information management. Our approach is to consider both data and programs as ... -
Reputation-assisted utility maximization algorithms for peer-to-peer networks
(2008)Peer-to-peer networks are voluntary resource sharing systems among rational agents that are resource providers and consumers. While altruistic resource sharing is necessary for efficient operation, this can only be imposed ... -
Security and privacy in the internet of things using blockchain technology
(2019)The Internet of Things constitutes the latest paradigm shift in computing. We are soon going to be surrounded by billions of devices that will sense the real world and store produced data in the cloud. These data will ... -
A software-defined architecture and prototype for disaggregated memory rack scale systems
(2018)Disaggregation and rack-scale systems have the potential of drastically increasing TCO and utilization of cloud datacenters, while maintaining performance. In this paper, we present a novel rack-scale system architecture ... -
Towards dynamic and cooperative multi-device personal computing
(2007)In the 2WEAR project we have explored the paradigm of cooperative multi-device personal computing, where different wearable, portable and infrastructure elements communicate with each other in an ad-hoc fashion. The physical ... -
A trust-based exchange framework for multiple services in P2P systems
(2007)In this paper we propose fully distributed trust-based policies for p2p systems to regulate the exchange of different type of services and discourage misbehaviour. In a system of peers with different service valuations and ... -
Uplink allocation based on user actions for peer-to-peer Video-on-Demand
(2014)For more than a decade peer-to-peer networking technologies have met with huge success among Internet users, with peer-to-peer traffic already accounting for the largest part of the Internet's total traffic. Peer-to-peer ...
