5G and the Internet of everyone: motivation, enablers, and research agenda
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Open AccessAs mobile broadband subscriptions grow twice as fast as the fixed ones and the Internet of Things comes forth, the 5G vision of the Internet of Everything (people, devices, and things), becomes a substantial and credible ... -
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 ... -
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 ... -
A LoRa-Based communication system for coordinated response in an earthquake Aftermath
(MDPI, 2019)
Conference report
Open AccessThe response conducted by emergency units after natural disasters, such as earthquakes, has to be coordinated, fast, and efficient in order to rescue and care for the victims, keeping all the population—and the units ... -
A minimalistic distance-vector routing protocol for LoRa mesh networks
(2021-06-15)
External research report
Open AccessLoRa has gained traction in the Internet of Things (IoT) domain as a Low Power, Wide Area Network(LPWAN) radio technology, providing low-power and long-range communication in the sub-GHz band. Most often it is used as part ... -
A monitoring system for distributed edge infrastructures with decentralized coordination
(Springer, 2019)
Conference report
Open AccessWe present the case of monitoring a decentralized and crowdsourced network infrastructure, that needs to be monitored over geographically distributed devices at the network edge. It is a characteristic of the target ... -
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 ... -
A simheuristic algorithm for service placement in community networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe growing demand for network connectivity has boosted the number of community networks (CNs). CNs are decentralized and self-organized communication networks owned and managed at the edge by volunteers. Due to the ... -
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 ... -
A two-stage multi-criteria optimization method for service placement in decentralized edge micro-clouds
(Elsevier, 2021-08)
Article
Restricted access - publisher's policyCommunity networks are becoming increasingly popular due to the growing demand for network connectivity in both rural and urban areas. Community networks are owned and managed at the edge by volunteers. Their irregular ... -
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 ... -
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 ... -
