Basic (Undergraduate) Studies: Μaster in Engineering (MEng) with Distinction (2001) at University of Portsmouth, England. Object of Studies: Electronic and Computing Engineering (Telecommunications). Postgraduate Studies: PhD in Electronic and Computing Engineering (close to completion) at University of Portsmouth, England.
In our days there is a continuous and intense effort towards the development of integrated methodologies for efficient traffic management in multi-service networks. In this research talk, a general framework for off-line Traffic Engineering (TE) of primary and backup paths, on-line routing of Quality of Service (QoS) and Best-Effort (BE) flows and restoration in multi-service networks will be presented. In the aforementioned framework, novel TE optimisation problems and heuristic TE algorithms are involved. Survivability against single or multiple node and/or link failure(s) is provided. Besides, today there is a strong effort towards the development of time and cost-effective methods for the design of wireless access networks (e.g. CDMA, UMTS). In this talk, new heuristic algorithms based on graph theory will be presented, which are capable of designing medium and large-scale wireless access networks at polynomial time. These algorithms have near-optimal performance. Also in this talk, an integrated approach for the methodical and efficient design of multi-layer hierarchical networks will be presented. This approach involves novel heuristic algorithms based on graph theory, which are capable of designing medium and large-scale networks at polynomial time and they have near-optimal performance.
