The Internet, social networks, power grids, gene regulatory networks, neuronal systems, food webs, social systems, and networks emanating from augmented and virtual reality platforms are all examples of complex networks. Collection and analysis of data from these networks is essential for their understanding. Traffic traces collected from various deployed communication networks and the Internet have been used to characterize and model network traffic, analyze network topologies, and classify network anomalies. Data mining and statistical analysis of network data have been employed to determine traffic loads, analyze patterns of users’ behavior, and predict future network traffic while spectral graph theory has been applied to analyze network topologies and capture historical trends in their development. Recent machine learning techniques have proved valuable for predicting anomalous traffic behavior and for classifying anomalies in complex networks. Further applications of these tools will help improve our understanding of the underlying mechanisms that govern behavior, improve their performance, and enhance their security of social networks such as Facebook, LinkedIn, Twitter, Internet blogs, forums, and websites.

Wireless Access Architecture: The Next 20 Years
The wireless community has been occupied by the 5G related developments for the last many years. As 5G moves from the standardization phase to the deployment phase, a new brainstorming endeavour has started for the subsequent generation (6G) wireless networks. The roots of today’s wireless access architecture (the terrestrial 4G & 5G cellular network) go back to 1940s. The access architecture has evolved substantially over the decades. However, rapid developments in a number of domains outside telecommunications, including those in aerospace and satellite industries as well as in artificial intelligence, will likely result in a disruptive transformation in the wireless access architecture in the next 20 years. In this talk, an ultra-agile, dynamic, distributed, and partly-autonomous vertical heterogeneous network (VHetNet) architecture with very low earth orbit satellites (VLEOs), high-altitude platform stations (HAPS), and drone BSs for almost-ubiquitous super-connectivity will be presented. In this disruptive setting, free-space optical (FSO) communications will play an important role in addition to the legacy radio communications. In the absence of a clear technology roadmap, the talk has, to a certain extent, an exploratory view point to stimulate further thinking and creativity in ICT research and innovation.
Dr. Halim Yanikomeroglu is a Full Professor in the Department of Systems and Computer Engineering at Carleton University, Ottawa, Canada. He has had extensive collaboration with
industry on 4G and 5G wireless technologies which resulted in 35 granted patents. During 2012-2016, he led one of the largest academic-industrial collaborative research programs on pre-
standards 5G wireless, sponsored by the Ontario Government and the industry. In Summer 2019, he started a new large-scale project on the 6G wireless network architecture. Dr. Yanikomeroglu
supervised 24 PhD & 28 MASc students (all completed with theses) as well as 14 PDFs; about a dozen of the former members of his research team have become faculty members. In addition,
his wireless lab at Carleton has hosted around 50 visiting scholars from around the world. He is a Fellow of IEEE (Institute of Electrical and Electronics Engineers), a Fellow of EIC (Engineering
Institute of Canada), a Fellow of CAE (Canadian Academy of Engineering), and a Distinguished Speaker for both IEEE Communications Society and IEEE Vehicular Technology Society. He
has been one of the most frequent tutorial presenters on the emerging wireless technologies. He served as the General Chair and Technical Program Chair of several major international IEEE
conferences; he also served in the Editorial Boards of several IEEE periodicals. He served as the Chair of IEEE Technical Committee on Personal Communications, and he is currently serving as
the Chair of the Steering Committee of IEEE’s flagship Wireless Communications and Networking Conference (WCNC). Dr. Yanikomeroglu received several awards for his research
and teaching including the IEEE Communications Society Wireless Communications Technical Committee Recognition Award in 2018.
AI-based Automation for Beyond 5G Networks
AI-based automation allows service providers to reduce CAPEX and OPEX costs and offer, via proper abstractions, infrastructure resources (radio, networking, computing) to vertical sectors traditionally alien to the telco industry (e.g., automotive, health, construction). In this talk we will review AI-enabled automation solutions and explore the concept of resources overbooking to maximize the revenue of infrastructure providers. Hierarchical control plane solutions will be considered to manage the network in an automated manner. Then, some early implementations of proof-of-concepts will be reviewed to evaluate the automation gains potential. Finally, we will illustrate how such automation solutions can be used in Beyond 5G networks comprising industry verticals.
