New methods for analysing the performance of multi-radio systems in emerging wireless networks

For the past years, analysts have been predicting a tremendous and continuous increase in mobile traffic, causing much of industry and academia to seek out methods to improve wireless network capacity. In the envisioned fifth-generation (5G) deployments, each user device may employ multiple radio access technologies for communicating with the network infrastructure or other proximate devices. With the growing number of such multi-radio consumer devices, network operators are increasingly willing to leverage spectrum across diverse radio technologies to boost capacity and enhance the quality of service. 

We propose a novel methodology for the performance evaluation of systems of multi-radio users, which is based on coupling stochastic nature of both spatial user locations and traffic time dynamics. By means of applying theoretical findings to future 5G technologies, where the distributed unlicensed-band network (e.g., WiFi) may take advantage of the centralized control function residing in the cellular network (e.g., 3GPP LTE), we classify the most widespread types of heterogeneous networks in terms of provided methodology and propose a set of analytical methods for each of them to evaluate and predict integrated cooperative behaviour on the system level.

Public defence of a doctoral dissertation on Tuesday, 1 September 2015

The doctoral dissertation of MSc Olga Galinina in the field of wireless communications titled “Analytical Performance Evaluation of Cooperative and Multi-Radio Concepts in Emerging Wireless Networks” will be publicly examined at the Faculty of Computing and Electrical Engineering of Tampere University of Technology (TUT) in Auditorium SJ204 in the Sähkötalo building on Tuesday, 1 September 2015 starting at 12:00.

The opponent will be Professor Ekram Hossain from the University of Manitoba,Winnipeg, Canada. Professor Yevgeni Koucheryavy from the Department of Electronics and Communications Engineering at TUT will act as Chairman.
