Research work in Telecommunications
Dr Konstantinos Katzis is currently working on dynamic spectrum assignment for cognitive radio networks. This is an on-going work that aims to create a broadband networks that are capable of supplying an order of magnitude greater capacity density than the current 4th generation proposals, thus approaching the 1Gbps/km2. The network is designed to operate in unlicensed bands for a start employing 802.16 standard, while a Reinforced Learning Support Database (RLSD) is formed to support its operation. Cognitive enabled mobile users can benefit from this database and based on the data from the RLSD they can perform a better channel selection for their use. Furthermore users have the flexibility to enjoy high capacity links if the local traffic and time permits. Dr Katzis is also a Management Committee member of COST action IC0902 “Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks”. He is also an active member of the Worldwide University Network (WUN) on Cognitive Communications (COGCOM). Furthermore, his research work focuses on mixed High Altitude stratospheric Platform (HAP)-terrestrial cognitive radio systems.
Previous work focused on “Resource Allocation Techniques for High Altitude Platforms” which dealt, for the first time, with the design of novel channel allocation techniques optimised for a High Altitude Platform architecture. Aspects of the telecommunication link, like wave propagation, antenna design and radio interference were considered to maximise user capacity and optimise system network performance. More specifically his work in this project was to model the three-dimensional communication system that includes ground users, ground base stations and a network of flying aerial platforms. It focused on providing service to maximum number of users and at the same time avoiding dropping any connected users. It simulated the movement of ground users and the positional and orientational movement of the flying platform. The model was implemented in MATLAB and C++ using C-MEX functionality. Traffic was based on Poisson Distribution for arrival and Exponential Distribution for the duration of the connection of the users. Results based on this novel channel allocation algorithm, showed clearly the optimum way to allocate users into different cells in order to ensure the best quality of service.
Research on Road Traffic Management
Dr Katzis has been involved with the modelling of road traffic activities as well as with the development of road traffic management systems using terrestrial or satellite systems. The aim of this work is in managing traffic while minimising potential road traffic accidents.
Research on Engineering Education
Dr Katzis (along with Dr Dimopoulos) haves been working towards increasing attractiveness of the Engineering discipline within Europe. Dr Katzis is a member of the EUGENE Network that aims in improving the impact of European Engineering Education (EE) on competitiveness, innovation and socio-economic growth in a global context. His latest work investigates the role of school counsellors in Cypriot high schools advising towards engineering disciplines. Results have been published in various conferences.
Research on Social Inclusion
Dr Katzis is currently involved in a project looking at the social inclusion of the elderly using technological means. The aim of this work is to conduct a social service related research to familiarise the elderly with the current mobile phone technology and stress out how it can improve their lives. Furthermore, it will look into why they have not used this technology so far for their benefit and what elderly are expecting from it. This is project funded by EUC in collaboration with the municipality of Nicosia and it’s Multipurpose Centre.
