Abstract
In the last four decades, discrete time queues have received, and continue to receive, considerable attention in research and also in applications to communication systems. This is partly because communication systems are more digital these days than analogue, and also because applying matrix analytic methods (MAM) to the analysis of discrete time queues can now be set up to analyze what had been considered as “difficult” problems in the past. In this presentation, PH (phase type) distributions and MAP (Markovian arrival process) will be introduced and the fundamentals of discrete time queues and will be presented. The analysis of discrete time queues using MAM will be discussed and how together these tools can be used for analyzing some current communication problems will be presented. Detailed example will be given for the non-pre-emptive queues. Few open problems in this research area will also be presented.
Biography
Attahiru S. Alfa is the SARChI Chair professor in Advance Sensor Networks (UP/CSIR co-hosted) at the University of Pretoria, and also Emeritus Professor of telecommunication systems at the University of Manitoba. Dr. Alfa is a well-known researcher in the field of queueing theory and matrix analytic methods. His general research interests include, but not limited to, the following areas: queueing theory and applications, optimization, performance analysis and resource allocation in telecommunication systems, modeling of communication networks, analysis of cognitive radio networks, modeling and analysis of wireless sensor networks, and smart cities. Dr. Alfa’s most recent research focus covers the mathematical modeling of wireless sensor networks, cognitive radio networks, network restoration tools for wireless sensor networks, the role of 5G on IoT, and energy harvesting and its management in wireless sensor nodes. He has authored two books, “Queueing Theory for Telecommunications: Discrete Time Modelling of a Single Node System”, published by Springer in 2010, and “Applied Discrete-Time Queue” published in 2015, also by Springer, as a second edition of the first book.
