Title: Green Wireless Networks
Abstract:
Energy consumption has become a major concern on wireless networks due to economical and environmental related issues. In order to cope with the increasing demand for wireless access, Mobile Network Operators (MNOs) have to massively deploy more wireless infrastructures. In the recent years, MNOs have faced the following dilemma in terms of energy wastage: how to increase the system capacity while at the same time saving energy? In this talk, I will present the main aspects behind the design of eco-friendly wireless networks with emphasis on how to reduce the energy wastage from the operational standpoint. Challenges and state-of-the art research topics in this area will be presented in-depth.
Biography:
Glaucio Haroldo Silva de Carvalho received his B.Sc., M.Sc., and Ph.D. degrees from Federal University of Para, Brazil, respectively in 1999, 2001, and 2005, all in electrical engineering. From 2005 to 2008, he worked as an Assistant Professor and Chair of the Faculty of Information Systems, at the Federal University of West Para, Brazil. Since 2008, he has worked as Associate Professor at the Institute of Natural and Exact Sciences, Federal University of Para, Brazil, serving the Faculties of Statistics and Computing. Since January 2013, he has been with the DABNEL Lab, Department of Computer Science at Ryerson University, Toronto, Canada, working as Visiting Postdoctoral Fellow. His current research interests include the application of operational research methods for the optimization of resource management in next generation wireless networks, design of eco-friendly network protocols, dynamic spectrum access protocols, and resource management schemes for cloud computing. Currently, he serves as Associate Editor of the Computers & Electrical Engineering Journal, Elsevier.

Title: Mobile Opportunistic Networks: Motivation and State-of-the-art Research Challenges
Abstract:
Contrary to General Ad Hoc Networks and Systems (GAHNS), which provide a one-size-fits-all basis for all kinds of applications, mobile opportunistic networks (OppNets) are a kind of Specialized Ad Hoc Networks and Systems (SAHNS), each of which is suitable as a foundation for a restricted class of applications or an individual application. It is expected that SAHNS, thanks to exploiting salient features of their application areas, will result in overcoming barriers that make GAHNS based solutions technically infeasible or inefficient. Oppnets constitute a new class of wireless ad hoc networks that allow a pre-designed seed Oppnet to grow into an expanded Oppnet by finding and using external devices and systems, which become their helpers. Significantly, these helpers can be employed opportunistically at low or even no cost. This talk will present a general introduction to Oppnets and their current state-of-the-art related research challenges, including those related to routing in such networks.
Biography:
Isaac Woungang received his M.S. and Ph.D. degrees, all in Mathematics, from the Universite de la Mediterranee-Aix Marseille II and Universite du Sud, Toulon & Var, France, in 1990 and 1994 respectively. In 1999, he received a M.S. degree from the INRS-Materials and Telecommunications, University of Quebec, Montreal, Canada. From 1999 to 2002, he worked as a software engineer at Nortel Networks. Since 2002, he has been with Ryerson University, where he is now an Associate Professor of Computer Science and Coordinator of the Distributed Applications and Broadband (DABNEL) Lab at Ryerson University. During his sabbatical (2008-09), he was a Visiting Professor at National Ilan University, Taiwan. His current research interests include network resource allocation in next generation wireless networks, network security, and routing in opportunistic networks. Dr. Woungang has published 10 book chapters and over 80 refereed technical articles in scholarly international journals and proceedings of international conferences. He serves as Editor in Chief of the International Journal of Communication Networks and Distributed Systems (IJCNDS), Inderscience, UK, as Associate Editor of the International Journal of Communication Systems (IJCS), Wiley, and the Computers & Electrical Engineering Journal, Elsevier. He edited seven (7) books in the areas of wireless ad hoc networks, wireless sensor networks, wireless mesh networks, pervasive computing, and coding theory, published by reputed publishers such as Springer, Elsevier, Wiley, and World Scientific. He has been serving as Symposium Chair of the 29th IEEE Symposium on Reliable Distributed Systems (SRDS 2010), Organizing Chair of the International workshop on Dependable Network Computing and Mobile Systems (DNCMS), Track Chair, and Program Chair of over a dozen International conferences. Since January 2012, he has been serving as Chair of Computer Chapter, IEEE Toronto Section.
