Arrowhead compliant virtual market of energy (2014)
Presentation / Conference Contribution
Ferreira, L. L., Siksnys, L., Pedersen, P., Stluka, P., Chrysoulas, C., le Guilly, T., …Pedersen, T. (2014). Arrowhead compliant virtual market of energy. In Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA). https://doi.or

Industrial processes use energy to transform raw materials and intermediate goods into final products. Many efforts have been done on the minimization of energy costs in industrial plants. Apart from working on “how” an industrial process is implemen... Read More about Arrowhead compliant virtual market of energy.

Enhancing service portability in upcoming 3G UMTS networks & security aspects (2010)
Presentation / Conference Contribution
Chrysoulas, C., Sklavos, N., & Kakarountas, A. P. (2010). Enhancing service portability in upcoming 3G UMTS networks & security aspects. In Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference. https://doi.org/10.1109/melcon.2010.54762

Compared to other wired networks, complexity in the 3G UMTS is due its interactions with different entities. Within the UMTS, services have to deal with a great number of different QoS, small user display, variant bandwidth and small battery power. M...

Integrating QoS management within a Web Service architecture (2009)
Presentation / Conference Contribution
Chrysoulas, C. (2009). Integrating QoS management within a Web Service architecture. In 2009 International Conference on Ultra Modern Telecommunications & Workshops. https://doi.org/10.1109/icumt.2009.5345617

Web Services are applications that expose functionality to consumers via public interfaces. Web-services support the concept of loosely coupled components, which in turn enables the development of more agile and open systems. However, this flexibilit...
