Department of Computer Science - University of Cyprus

Besides Colloquiums, the Department of Computer Science at the University of Cyprus also holds Other Presentations (Research Seminars, PhD Defenses, Short Term Courses, Demonstrations, etc.). These presentations are given by scientists who aim to present preliminary results of their research work and/or other technical material. Other Presentations serve as a forum for educating Computer Science students and related announcements are disseminated to the Department of Computer Science (i.e., the csall list):

The task of a communication network is to provide traffic transportation services between end users by conveying data from one node to another in a reliable and timely fashion. This task means that a network is a shared entity; its services should not be dedicated to only a pair of communicating entities but to as many entities possible during its operational lifetime. Network planners have always strived to design networks that achieve high user capacities and high quality of service, but have always faced the same limitation: the finite amount of resources which a network has available for utilization in order to fulfill its task. In this talk we will discuss the important issues that arise when trying to support video streams and other real-time multimedia applications over wireless networks. First we will illustrate the importance of applications' adaptability and QoS awareness in mobile wireless networks using as an example 3G cellular wireless networks. Then we will characterize the requirements of real-time multimedia applications and define the limitations of mobile wireless networks. Lastly, we will describe a new method for video stream adaptation based on Fuzzy Logic control, developed in the context of a UCY-funded research program.

Short Bio:
Dr. Vasos Vassiliou is a Lecturer at the Computer Science Department of the University of Cyprus since 2005. He is also the Associate Director of the Networks Research Laboratory (NetRL) at UCY. He held positions as a Visiting Lecturer at the same department (2004-2005) and as an Assistant Professor at the Computer Science Department of Intercollege (2002-2004). He has published several articles in International Conferences and Journals and participates actively in COST actions, local, and European Projects. His research interests include High Speed Network Architectures (MPLS), Mobile Networks (Mobile IP, MMPLS, Ad Hoc and Sensor Networks), Wireless Communications (Protocol enhancements for 3G/4G cellular wireless networks) and Quality of Service (QoS) and Traffic Engineering for computer and telecommunication networks. He holds an M.Sc. (1999) and a Ph.D. (2002) from the Georgia Institute of Technology both in Electrical and Computer Engineering. He is a member of IET (former IEE), IEEE, ACM, and participates in the Technical Program Committees of several international conferences, such as Globecom, VTC, PIMRC, WNET, EW. He is also an Associate Editor of the Journal of Telecommunication Systems.
