SITC Instructor of Telecommunication and Wireless Systems, Babatunde Samuel Ogunleye, has earned a PhD in Electrical Engineering from the University of Cape Town, South Africa.
Dr. Ogunleye’s PhD thesis entitled “WiMAX Spectrum Virtualization and Network Federation” developed novel frameworks for the improved management of the radio frequency (RF) spectrum for wireless broadband networks, particularly for the wireless 4G technology known as the Worldwide Interoperability for Microwave Access (WiMAX). His PhD research findings have been published and indexed in reputable publishing databases such as Springer and IEEE Xplore.
Dr. Ogunleye joined AUN in Spring 2010. He also holds an MSc in Wireless Communication Systems from Brunel University, London, and a B.Eng. in Information Communication Technology from Covenant University, Ota.
President Dawn Dekle and Provost Muhammadou Kah have sent congratulatory messages to Dr. Ogunleye on his scholarly achievement, charging him to aim for greater feats with AUN. Dean Mathias Fonkam of SITC and the entire SITC faculty have also congratulated Dr. Ogunleye.
Dr. Ogunleye, on his part, has affirmed his commitment towards helping AUN become a world-renowned university in the development of innovative technological solutions for Africa and for generating quality research outputs.
Meanwhile Dr. Ogunleye presented a research paper at the 13th IEEE International Conference on Wireless and Mobile Computing, Networking and Communications (WiMOB 2017) in Rome, Italy.
His paper, “WiMAX Network Federation Using Spectrum Virtualization,” discussed and described an innovative solution that enables the mobile network operators of the 4G Worldwide Interoperability for Microwave Access (WiMAX) to share their very scarce and licensed radio frequency spectrum based on a negotiation platform using the concepts of spectrum virtualization and network federation. Spectrum virtualization means the sharing and abstraction of the wireless spectrum (air interface) both in the time and frequency domains, while network federation involves providing an avenue for combining network resources between similar networking domains to achieve a greater technological and administrative convergence for the sharing of resources.
Dr. Ogunleye’s paper explains the development of a novel architecture and algorithms that allows multiple WiMAX base-stations with overlapping cellular coverage areas to negotiate the sharing of their spectrum resources in order to satisfy the quality of service (QoS) requirements for the various network services that they render to their subscribers. The paper’s solutions will help WiMAX mobile operators save money in terms of capital expenditure in relation to the purchase of additional licensed spectrum from regulatory authorities. The solutions described in the paper can also be adopted in other 4G wireless technologies like the Long Term Evolution (LTE).
Dr. Ogunleye says he is delighted to have represented AUN at the WiMOB 2017 conference and also to have been the only African university representative at the conference. The WiMOB conference is a highly ranked IEEE conference with an average of 30 percent paper acceptance rate.
