A catallactic market for data mining services.
(2007)
Article
Open AccessWe describe a Grid market for exchanging data mining services based on the Catallactic market mechanism proposed by von Hayek. This market mechanism allows selection between multiple instances of services based on operations ... -
A distributed auctioneer for resource allocation in decentralized systems
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Open AccessIn decentralized systems, nodes often need to coordinate to access shared resources in a fair manner. One approach to perform such arbitration is to rely on auction mechanisms. Although there is an extensive literature ... -
Advances in wireless community networks with the community-lab testbed
(2016-07)
Article
Open AccessBeyond traditional telecom providers, citizens and organizations pool their own resources and coordinate in order to build local network infrastructures to address the digital divide in many parts of the world. These ... -
A dynamic periodicity detector: application to speedup computation
(IEEE, 2001-04)
Conference report
Open AccessWe propose a dynamic periodicity detector (DPD) for the estimation of periodicities in data series obtained from the execution of applications. We analyze the algorithm used by the periodicity detector and its performance ... -
A Hayekian self-organization approach to service allocation in computing systems
(Elsevier, 2005)
Article
Open AccessFuture ‘on-demand’ computing systems, often depicted as potentially large scale and complex Service-Oriented Architectures, will need innovative management approaches for controlling and matching services demand and supply. ... -
A lightweight service placement approach for community network micro-clouds
(2019-03)
Article
Open AccessCommunity networks (CNs) have gained momentum in the last few years with the increasing number of spontaneously deployed WiFi hotspots and home networks. These networks, owned and managed by volunteers, offer various ... -
A look at energy efficient system opportunities with community network clouds
(CEUR-WS.org, 2014)
Conference report
Open AccessCommunity networking is an emerging model of a shared communication infrastructure in which communities of citizens build and own open networks. Community networks offer successfully IP-based networking to the user. In ... -
Analysis of the social effort in multiplex participatory networks
(Springer, 2014)
Conference report
Open AccessCommunity networks are participatory connectivity solutions for citizens where all the resources are owned, managed and controlled by the participants. As a natural evolution, in recent years some initiatives have flourished ... -
A new approach to role and position detection in networks
(2016-06)
Article
Open AccessWe rethink and extend the concepts of position and role in a network, basing them on various well-known measures that were not previously associated with these concepts, such as geodesic distance and modularity. The ... -

ARTA: An economic middleware to exchange pervasive energy and computing resources
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Open AccessStudies reveal that an integrated system of smart grid and cloud computing ecosystems can better attain the energy efficiency objectives, considering all the aspects. To facilitate the integration, in this paper, we introduce ... -
Assessing a distributed market infrastructure for economics-based service selection
(Springer, 2007)
Conference lecture
Open AccessService selection is an important issue for market-oriented Grid infrastructures. However, few results have been published on the use and evaluation of market models in deployed prototypes, making it difficult to assess ... -
Assessing the participatory design of a project-based course on computer network applications
Conference report
Open AccessNew teaching methodologies which foster student involvement, such as project-based learning, are nowadays part of the study curriculum of many engineering schools. Project-based learning courses, however, often build upon ... -
A summary of virtualization techniques
(Elsevier, 2012)
Article
Restricted access - publisher's policyNowadays, virtualization is a technology that is applied for sharing the capabilities of physical computers by splitting the resources among OSs. The concept of Virtual Machines (VMs) started back in 1964 with a IBM project ... -
A trace-scaling agent for parallel application tracing.
(IEEE, 2002)
Conference report
Open AccessTracing and performance analysis tools are an important component in the development of high performance applications. Tracing parallel programs with current tracing tools, however, easily leads to large trace files with ... -
Building microclouds at the network edge with the Cloudy platform
