He received his BSc and MSc in Electrical Engineering from Electronics and Electrical Communication Department at Faculty of EngineeringCairo University in 2000 and 2002 respectively. His research interests span different topics in wireless mobile networking such as multimedia streaming, cognitive networking, energy efficient networking, mobility and resource management, and modeling and performance evaluation. His research received several awards including the first DASH Industry forum award in MMSys 2017, Best Demo Award in LANMAN 2016, the best paper award in IFIP Networking 2005 conference, spotlight paper for IEEE Trans. Mobile Computing (June 2010), and UCC commercialization award 2010. He served as a technical reviewer for various journals and conferences including, but not limited to, the IEEE Trans. on Mobile Computing, IEEE Transactions on Wireless Communications, IEEE Communication Mag., ICC, WCNC, VTC, Globecom, IFIP Networking. He served on the organizing committee and the technical program committee of several conferences such as IEEE PIMRC 2011, IEEE CCNC 2009 & 2010.

Research Interests

My research interests lie in the broad areas of general distributed systems and wireless Internet technologies, including next-generation wireless networks and systems, smart cities, and multimedia communications. In these areas, my research focuses on developing new algorithms, protocols, and solutions to ensure the best user experience.  This goal is attained by tackling key problems,  such as mobility and resource management.
