Biography
Dr. Toni Janevski: Professor at the Faculty of Electrical Engineering and Information Technologies, Ss. Cyril and Methodius University in Skopje, Macedonia. He received his Dipl. Ing., M.Sc. and Ph.D. degrees in electrical engineering all from Faculty of Electrical Engineering and Information Technologies, Ss. Cyril and Methodius University in Skopje, in 1996, 1999 and 2001, respectively. In the past, during 1996-1999 he has worked at the Macedonian mobile operator Mobimak (currently T-Mobile, Macedonia), contributing to the planning, dimensioning and implementation of the first mobile network in Macedonia. From 1999 he is with Faculty of Electrical Engineering and Information Technologies in Skopje. In 2001 he has conducted research in optical communication at IBM T. J. Watson Research Center, New York. Also, during 2005-2008 he was a Member of the Commission of the Agency for Electronic Communications (AEC) of the Republic of Macedonia, where he contributed towards the introduction of new technologies in Macedonia, such as WiMAX and 3G mobile networks, as well as new operators and services. During the periods 2008-2012 and 2012-2016 he is an elected member of the Senate of the Ss. Cyril and Methodius University in Skopje. In 2009 he has established Macedonian ITU (International Telecommunication Union) Centre of Excellence (CoE) as part of the Europe’s CoE network, and serves as its Coordinator since than. He is an author of the book titled “Traffic Analysis and Design of Wireless IP Networks”, which is published in 2003 by Artech House Inc, Boston, USA. Also, he is author of the book “Switching and Routing”, written in Macedonian language, published in September 2011 by the Ss. Cyril and Methodius University in Skopje, for which in May 2012 he has won the “Goce Delchev” award, the highest award for science in the Republic of Macedonia. He has published more than 130 research papers and has led research and applicative projects in the area of Internet technologies and mobile and wireless networks. He is a Senior Member of IEEE. His research interests include Internet Technologies, Mobile, Wireless and Multimedia Networks, Traffic Theory, Quality of Service, Design and Modeling of Telecommunication Networks, as well as Next Generation Networks.

IEEE 802.16 standard supports five different service classes in order to support different needs of the mobile users with different QoS criteria. But, this standard doesn’t specify admission control and scheduling mechanisms and so far many solutions are proposed in the science world. In this paper we propose priority based uplink scheduling scheme for IEEE 802.16 standard that improves the QoS performances of the five WiMAX service classes, especially of the ertPS service class. Simulation experiments and analysis are done choosing the most adequate WiMAX simulator and the ns-2 simulation tool. Traffic load of the ertPS connections is changed from low to high in order to perform detailed performance analysis of the results. Results given in average delay, average jitter and average throughput are evaluated and compared with so far known uplink scheduling mechanism. The results show that our proposed uplink scheduling scheme based on the priority of the service classes improves the QoS performances especially in high loaded scenarios.
