Active projects

The elastic Wireless Networking Experimentation (eWINE) is a research project funded by the European Comission under the Horizon2020 programme (Call: H2020-ICT-2015. Topic: ICT-12-2015). The main goal of eWINE is to realize elastic networks that can scale to a high number of users in a short timespan through the use of an agile infrastructure (intelligent software and flexible hardware), enabling: 1) dynamic on-demand end-to-end wireless connectivity service provisioning, 2) elastic resource sharing in dense heterogeneous and small cell networks (HetSNets), 3) intelligent and informed configuration of the physical layer.

The main objective of Fed4FIRE-ETEL is to fully integrate the existing wireless sensor network testbed LOG-a-TEC into the Fed4FIRE federation. This will be achieved by adopting Fed4FIRE federation interfaces and components, creating the adapters between LOG-a-TEC and the Fed4FIRE federation platform, validating the newly federated testbed and making it available to the community of experimenters through the common Fed4FIRE portal.

SUNSEED proposes an evolutionary approach to exploitation of common, converged communication infrastructures for future smart energy grid services. Its life cycle matches the joint communication networking operations of DSO and telecommunication operator and consists of six steps: overlap, interconnect, interoperate, manage, plan and open. Joint communication networking operations steps start with analysis of regional overlap of DSO and telecommunications operator infrastructures. Overlap is discovering what vital DSO energy grid infrastructure locations (e.g. DEG, substations) are geographically covered by both DSO and telecom communication networks and underlying infrastructure (e.g. ducts, energy cabling). Coverage can be in wireline (PLC, xDSL, fiber) or wireless (WiFi, Gprs, UMTS, HSPA, LTE) technologies. Interconnection step assures communication on the physical layer between DSO and telco, whereas interoperation provides network visibility and reach of smart grid nodes and vital locations from both DSO and telecom sides. A virtual network(s) layer on top of physical infrastructure is formed that ensures secure communication. Monitoring, control and management acts upon measurement data streams from wide are sensors and smart meters. It employs novel intelligent real time analytical knowledge discovery methods. For full utilisation of future network planning, we will integrate various public databases. Applications build on open standards (W3C) with exposed application programming interfaces (API) to 3rd parties enable creation of new businesses related to energy and communication sectors (e.g. virtual power plant operators, energy services providers for optimizing home energy use) or enable public wireless access points (e.g. WiFi nodes at DEG points). SUNSEED life cycle steps promise much lower investments and total cost of ownership for future smart energy grids that will cover large, dense distributed energy generation and e-car charging infrastructures.

Past projects

  • OVE@PZ (SMER+)

OVE@PZ is a nationally funded applied research project on control modules and information infrastructure for the integration of renewable energy modules in smart buildings.

Recent events have shown that in the aftermath of an emergency, disaster or any related tremendous unexpected events, a reliable communication infrastructure plays an important role in providing critical services including emergency recovery operations, critical infrastructure restoration, post-disaster surveillance etc. In most of the cases, immediately after a large scale disaster, the normal terrestrial network infrastructure is seriously compromised and cannot guarantee reliable and large scale coverage for rescue teams and citizens. Current mission critical communication systems including PPDR (Public Protection for Disaster Relief) systems are heavily limited in terms of network capacity and coverage. They are not designed for or suitable to address large scale emergency communication deployments immediately after the disaster scenarios where these networks can provide dependable and resilient network connectivity at higher data rates over large coverage areas. Moreover, PPDR systems are limited by interoperability barriers and the technological gap with commercial technologies and evolving standards.

Furthermore, the first responder devices and terminals are getting smarter with new applications supporting packet data with integrated sensors and other monitoring and the availability of multimode heterogeneous embedded receivers. Such improvements call for a marked increase in capacity and energy demands for the first responder (FR) user terminals. Further, there is a large demand in the PPDR community for higher bandwidth emergency communication infrastructure to cater for the new mission critical services with very high throughput and low-delay requirements during the immediate post-emergency period (including real-time video streaming and video surveillance, exchange of high resolution pictures etc). Also some foreseen/unforeseen events with large aggregation of professional and consumer users such as e.g. big sport events, road shows or concerts require high capacity and/or dedicated coverage that the legacy terrestrial network infrastructure cannot provide rapidly.

These factors underline an urgent requirement for a rapidly deployable multi-purpose, multi service and multi-band interoperable and integrated network infrastructure capable of supporting reliable high data rate applications to serve large scale disaster emergency situations and the temporary event scenarios.

  • »Observe, infer, act« (European Regional Development Fund, MIZS, 2014-2015)

The projects aims to develop an eLearning tool that promotes interactive learning through integrating and using different data sources (sensors, open data, sensor nodes, RFID etc.). Observe, infer and act eLearning tool is developed as a web-based service and mobile application. It enables its users to: (1) choose data from different data sources and create diverse data visualizations (observe), (2) analyse data, make logical inferences and scenarios for the chosen data streams (infer) and (3) initiate action (e.g. if the temperature is 25°C, send me an SMS). The baseline technologies and solutions are based on VIDEK (lightweight software suite enabling device interaction, data handling and user management) and UMKO (a basic rule engine, which executes tasks sequentially without any indexing and algorithms). It is developed as a modular platform, which allows the users to add additional data streams and develop new functionalities. The project partners and representatives of the Advisory board pay special attention to make the eLearning tool user friendly and easy to use in a variety of school subjects. The developed eLearning service is suitable for primary and secondary schools as well as higher education students; it stimulates new ways of teaching, augments traditional learning processes and promotes personal and data-driven learning.

CITI-SENSE will develop “citizens’ observatories” to empower citizens to contribute to and participate inenvironmental governance, to enable them to support and influence community and societal priorities andassociated decision making. CITI-SENSE will develop, test, demonstrate and validate a community-basedenvironmental monitoring and information system using innovative and novel Earth Observation applications.To achieve this, the project will: (i) raise environmental awareness in citizens, (ii) raise user participation insocietal environmental decisions and (iii) provide feedback on the impact that citizens had in decisions. It willaddress the call’s request for effective participation by citizens in environmental stewardship, based on broadstakeholder and user involvement in support of both community and policy priorities. The project aims to learnfrom citizen experience and perception and enable citizenship co-participation in community decision making andco-operative planning.

The concept of CITI-SENSE rests on three pillars: technological platforms for distributed monitoring; informationand communication technologies; and societal involvement. Three pilot case studies will focus on a range ofservices related to environmental issues of societal concern: combined environmental exposure and healthassociated with air quality; noise and development of public spaces, and indoor air at schools. Attention willbe given to representativeness of citizen participation. The case studies will be designed in collaboration withcitizens’ groups and decision makers. They will be based on distributed data collection using innovative static,portable and personal devices (low-cost reliable microsensor packs) that communicate with a data repositoriesthrough mobile phones or other devices. Development of participatory methods, data management strategies,and applications to facilitate exploitation of the data and information for policy, and society, will be done.

  • Sensor and information management support (SMER+)

Sensor and information management support is a nationally funded applied research project on intelligent caravans.

  • APRICOT (ARRS, 2011-2013)

The “Advanced procedures for interactive composition of sensor networks project” starts from the hypothesis that by applying SOA principles it is possible to develop advanced procedures for the interactive composition of sensor networks on demand and thus exploit shared heterogeneous sensor resources assuming the knowledge of their characteristics, functionality, the context and accessibility. Since we will rely on the use of semantic technologies for discovery and composition of sensor resources we refer to the composed networks as semantic sensor networks.

The main objective of the project is to use semantic technologies to annotate and subsequently search for, discover, and reason upon sensor and associated communication resources, and on demand compose those resources into dynamic global sensor infrastructure. By having data on shared sensors instead on available sensor data, we make possible the interaction with sensors, so we can reuse them and set their parameters according to the needs of a particular application.

  • CREW (FP7 – IP, 2011-2015)

The main target of FP7-CREW is to establish an open federated test platform, which facilitates experimentally-driven research on advanced spectrum sensing, cognitive radio and cognitive networking strategies in view of horizontal and vertical spectrum sharing in licensed and unlicensed bands.

The CREW platform incorporates 5 individual wireless testbeds incorporating diverse wireless technologies (heterogeneous ISM, heterogeneous licensed, cellular, wireless sensor) augmented with State-of-the-Art cognitive sensing platforms.

The CREW project started in October 2010 with a consortium of 7 partners and was enlarged in July 2011 with the 8th partner. To extend the use of the federated testbeds to external researchers, two open calls are planned.

The main objective of the Project is to identify and coordinate EO activities in the wider Balkan region and to pave the way for future full inclusion of all Balkan countries into GEO.

The PlanetData project is built around three objectives that together ensure the creation of a durable community made up of academic and industrial partners. This community will be supported in conducting research in the large-scale data management area through the provision of data sets and access to tailored data management technology. From the research point of view, the focus is on large-scale data management. Sensorlab provides sensor data, raw and annotated and services based on these.

In the frame of the OPCOMM Competence Centre we will design an open communication platform for the development of new cutting-edge services and applications for the Future Internet. Special attention is given to the applicability of services, quality of user experience, the applicable value of data and content, and the interaction with the “material world”, i.e. various devices, objects and processes. This requires efficient interaction between the smart user terminals, appliances and objects, contextually dependent services, and the communication network. The programme encompasses research, design, and prototype development with the final demonstration of new solutions.

The SensorLab team is focused on gathering different types of data from sensor networks and on context awareness in support of services and application for object management. Moreover, it is concerned with pre-processing of data and metadata and its transfer to the core platform through appropriate data interfaces. In this respect, SensorLab will give special emphasis on the investigation of semantic technologies for sharing, searching, virtualizing and dynamic composition of sensor nodes.

  • COST Action IC0902 ”Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks”

The main objective of the Action is to integrate the cognitive concept across all layers of communication systems, resulting in the definition of a European platform for cognitive radio and networks. The Action proposes coordinated research in the field of cognitive radio and networks. The cognitive concept applies to coexistence between heterogeneous wireless networks, that share the electromagnetic spectrum for maximum efficiency in resource management. Several efforts are currently in place in European research centers and consortia to introduce cognitive mechanisms at different layers of the communications protocol stack. This Action goes beyond the above trend by integrating the cognitive concept across all layers of system architecture, in view of joint optimization of link adaptation based on spectrum sensing, resource allocation, and selection between multiple networks, including underlay technologies. The cross-layer approach will provide a new perspective in the design of cognitive systems, based on a global optimization process that integrates existing cognitive radio projects, thanks to the merge of a wide-range of expertise, from hardware to applications, provided by over 30 academic and industrial partners. The final result will be the definition of a European platform for cognitive radio and networks. To reach this goal, algorithms and protocols for all layers of the communications stack will be designed, and a set of standard interfaces as well as a common reference language for interaction between cognitive network nodes will be defined.

The main objective of WiNeMo is to advance the state-of-the-art concerning networking aspects of scenarios integrating moving objects of the most varied kinds, ranging from personal use devices to sensors, into the Internet of the Future. In particular, the Action will coordinate the development of new algorithms, techniques, protocols models and tools that will facilitate the integration of moving objects into pervasive and ambient communications. The Action will foster cooperation among researchers at European and global level by contributing to the coordination and defragmentation of research efforts across Europe in the area by creating an open forum for academia and industry. As a consequence, the Action will play a supporting role to European industry – including SMEs – and will enhance cooperation between industry and academia in the area of networking support for moving objects. The Action will seek active cooperation with existing COST Actions and foster relationships with external bodies such as Internet Engineering Task Force (IETF); Open Mobile Alliance (OMA); the Standardization and Radiocommunication Sectors of the International Telecommunication Union (ITU); European Telecommunications Standards Institute (ETSI), Institute of Electrical and Electronics Engineers (IEEE) and The 3rd Generation Partnership Project (3GPP). The establishment of links with international (e.g. FP7 programmes) and national research projects is deemed as an essential goal which will be proactively pursued throughout the Action’s lifetime.

Wireless transmission via optical carriers opens doors of opportunity in areas as yet largely unexplored. Offering significant technical and operational advantages, optical wireless communication (OWC) can be, in some applications, a powerful alternative to and, in others, complementary to existing radio frequency (RF) wireless systems. Variations of OWC can be employed in a diverse range of communication applications ranging from very short-range (on the order of millimetres) optical interconnects within integrated circuits through outdoor inter-building links (on the order of kilometres) to satellite links (larger than 10,000 kilometres). In many respects, OWC research is still in its infancy and calls for extensive research to begin to harness the enormous potential of the optical spectrum. This COST Action will serve as a high-profile consolidated European scientific platform for interdisciplinary OWC research activities, spanning from characterization of diverse propagation media to modeling, design and development of devices, components, algorithms/protocols and systems. It will make significant contributions to the fundamental scientific understanding, technical knowledge, engineering design and applications while promoting community awareness of this emerging field. Development of novel and efficient communication technologies resulting from integrated research activities made possible through this Action will be a significant enabler for future-generation heterogeneous communication networks supporting a wide range of wireless services/applications.

Random network coding emerged through an award-winning paper by R. Koetter and F. Kschischang in 2008 and has since then opened a major research area in communication technology with widespread applications for communication networks like the internet, wireless communication systems, and cloud computing. It allows transmitting information through a network by disregarding any of its topological features. As in traditional algebraic coding theory, two main research directions in random network coding are (1) existence and construction of good and optimal network codes, (2) efficient encoding and decoding schemes for a given network code.

Restriction to the so-called Grassmannian codes has proven to be advantageous and leads to the theory of designs over GF(q). Worldwide, there exists a larger number of workgroups focusing on this topic, which includes several groups located in Europe. This COST Action will set up a European research network and establish network coding as a European core area in communication technology. Its aim is to bring together experts from pure and applied mathematics, computer science, and electrical engineering, who are working in the areas of discrete mathematics, coding theory, information theory, and related fields.

sprejemna_postaja_projektAfter successful conclusion of the previous ESA PECS project SatProSi (Satellite Propagation Slovenia), SatProSi-Alpha project “Ka/Q-band Propagation Measurements and Modelling – Slovenian Contribution to the Alphasat TDP#5 Scientific Mission” was approved.

The aim of SatProSi-Alpha is to participate in the propagation campaign of the Alphasat Aldo Paraboni scientific experiment. For this purpose, a new sophisticated beacon receiver station has been set‑up in August 2015 at Jozef Stefan premises in Ljubljana. It is equipped with a tracking mechanism and it receives 4 channels (co- and cross-polar components of satellite beacons at Ka- and Q-band). The measurements will be collected and post-processed. First and second order statistics of attenuation will be calculated and the depolarisation behaviour shall be studied. Rainfall rate statistics will also be obtained from a near-by meteorological site and from co-located rain gauge. Finally, the results shall be used as a contribution to the common European-wide satellite channel model.

  • ESA PECS project “Satellite Propagation Slovenia – SatProSi” (2011-2014)


SatProSi, project “Ka/Q-band Propagation Measurements and Modelling for the Design of Prediction and Impairment Mitigation Techniques” is a 3 year project for the European Space Agency (ESA), performed in the scope of Plan for European Cooperating States (PECS). The main goal of the project is to establish a Ka-band band satellite-beacon measuring site in Ljubljana, Slovenia and to statistically analyse the results. The task has already been successfully accomplished. SatProSi has thus become the first such satellite propagation experiment, to be carried out in Slovenia as well as in the broader region of the Balkans.

A low-cost beacon receiver has been developed specifically for the project, based on SDR (Software Defined Radio) technology. A GNU Radio software development toolkit and USRP (Universal Software Radio Peripheral) were used for application development. The application has been made publicly available as an open source code via the GitHub hosting service (

In 2013 a network of three low-cost SDR-based Ka-band beacon receivers has been established for the purpose of site diversity experiment, one in Ljubljana and other two at the distance of 26 and 40 km from Ljubljana (Lisec, Krvavec). More than one year of measurements, collected in Ljubljana, has already been processed and statistics of in-excess attenuation and rainfall rate have been calculated.

In the future, the project team aims to take the project to the next level, by conducting measurements of the Q-band beacons from the Alphasat satellite.
