Dusit Niyato and Luigi Atzori ran a Seminar@SystemX on March 3 at the LINCS laboratory in Paris.


The talk starts by presenting the current approaches for a QoE-aware service management in the Internet, i.e., application oriented or network management, which are mostly characterized by the tools available by the stakeholders implementing the process and also by their own interests. Then, the current limits and issues of these approaches are highlighted, together with the current directions of development in the field. These are mostly characterized by a strong evolution towards the virtualization of the services through the introduction of the SDN and NFV paradigms. These allow for a more flexible management of the services with a better control of the QoE and for a potential stronger cooperation among the different actors involved in the service provisioning chain.


LuigiLuigi Atzori (SM’09) is Associate Professor at the Department of Electrical and Electronic Engineering at the University of Cagliari (Italy), where he leads the laboratory of Multimedia and Communications with around 15 affiliates (http://mclab.diee.unica.it). L. Atzori research interests are in multimedia communications and computer networking (wireless and wireline), with emphasis on multimedia QoE, multimedia streaming, NGN service management, service management in wireless sensor networks, architecture and services in the Internet of Things. He is the coordinator of the Marie Curie Initial Training Network on QoE for multimedia services (http://qoenet-itn.eu), which involves ten European Institutions in Europe and one in South Korea. He has been the editor for the ACM/Springer Wireless Networks Journal and guest editor for many journals, including the IEEE Communications Magazine, the Springer Monet and the Elsevier Signal Processing: Image Communications Journals. He is member of the steering committee for the IEEE Trans. on Multimedia, member of the editorial board of the IEEE IoT, the Elsevier Ad Hoc Networks and the Elsevier Digital Communications and Networks journals. He served as a technical program chair for various international conferences and workshops. He served as a reviewer and panelist for many funding agencies, including H2020, FP7, Cost and Italian MIUR.


Dusit Niyato, professor at the School of Computer Science and Engineering of the Nanyang Technological University in Singapore, ran the second part of the seminar on the theme “Joint Cyber Insurance and Security-as-a-Service Provisioning in Cloud Computing”


As computing services are increasingly cloud-based, corporations are investing in cloud-based security measures. The Security-as-a-Service (SECaaS) paradigm allows customers to outsource security to the cloud, through the payment of a subscription fee. However, no security system is bulletproof, and even one successful attack can result in the loss of data and revenue worth millions of dollars. To guard against this eventuality, customers may also purchase cyber insurance to receive recompense in the case of loss. To achieve cost effectiveness, it is necessary to balance provisioning of security and insurance, even when future costs and risks are uncertain. This presentation introduces a stochastic optimization model to optimally provision security and insurance services in the cloud. Since the model is a mixed integer problem, we also introduce a partial Lagrange multiplier algorithm that takes advantage of the total unimodularity property to find the solution in polynomial time. We show the effectiveness of these techniques using numerical results based on real attack data to demonstrate a realistic testing environment, and find that security and insurance are interdependent.


DusitDusit Niyato is currently an associate professor in the School of Computer Science and Engineering, at the Nanyang Technological University, Singapore. He received B.E. from King Mongkuk’s Institute of Technology Ladkrabang (KMITL), Thailand in 1999 and Ph.D. in Electrical and Computer Engineering from the University of Manitoba, Canada in 2008. He has published more than 300 technical papers in the area of wireless and mobile networking and authored the books “Resource Management in Multi-Tier Cellular Wireless Networks”, “Game Theory in Wireless and Communication Networks: Theory, Models, and Applications” and “Dynamic Spectrum Access and Management in Cognitive Radio Networks”. He won the Best Young Researcher Award of IEEE Communications Society (ComSoc) Asia Pacific (AP) and The 2011 IEEE Communications Society Fred W. Ellersick Prize Paper Award. He is a distinguished lecturer of the IEEE Communications Society. His works have received more than 13,000 citations (Google Scholar).

Currently, he serves as an area editor of IEEE Transactions on Wireless Communications (Radio Management and Multiple Access), an associate editor of IEEE Transactions on Communications, an editor of IEEE Communications Surveys and Tutorials (COMST), and IEEE Transactions on Cognitive Communications and Networking (TCCN). He was a guest editor of IEEE Journal on Selected Areas on Communications, special issue on Cognitive Radio Networking & Communications, and Recent Advances in Heterogeneous Cellular Networks. He is a Fellow of IEEE
