Title: Are we ready for 5G vision? What is next?

Abstract: 5G aims to support new and diverse sets of application classes like eMBB communications, uRLLC and mMTC. Supporting these services using a single framework has introduced a new vision and sets of challenges for wireless researchers in many layers of the protocol stacks, especially in the Physical, Medium Access and Network Layers. The trend on the variety and the number of mobile devices along with the mobile applications will certainly continue beyond 5G. In order to create a system that can support this trend, a wide range of technical challenges and requirements must be simultanously satisfied. A robust system that ensures extreme reliability and low latency under diverse channel conditions, while minimizing production and operational costs and maximizing power and spectrum efficiency is required. Cooperative networking capability and coexistence, dynamic and flexible utilization of wireless spectrum, highly flexible, cognitive and adaptive radio access technologies are key enablers in addressing these technical challenges. In this talk, the potential directions and research opportunities to address the challenges and requirements of the 5G vision will be discussed.

Title: Underwater Acoustic Communications: Fundamentals and New Results

Abstract: Underwater wireless communications rely on transmission of acoustic waves, since electro-magnetic waves propagate only over very short distances. Acoustic communications thus form an integral part of autonomous undersea systems, which find application in basic sciences (oceanography, marine biology), industry (off-shore oil, aquaculture), environment monitoring (climate, pollution, seismic disturbances) and security (search-and-rescue, surveillance).

Acoustic waves, however, are confined to low frequencies because of energy absorption (usually no more than several tens of kHz), and the bandwidth available for communication is extremely limited. Sound travels underwater at a very low speed (nominally 1500 m/s) and propagation occurs over multiple paths. Delay spreading over tens or even hundreds of milliseconds results in a frequency-selective signal distortion, while motion creates an extreme Doppler effect. The worst properties of radio channels—poor link quality of a mobile terrestrial channel, and long delay of a satellite channel—are thus combined in an underwater acoustic channel, which is often said to be the most difficult communication medium in use today.

The quest for bandwidth-efficient acoustic communications has progressed over the past few decades from an initial feasibility proof of phase-coherent detection, to the development of the first high-speed acoustic modem, and finally to a plethora of innovative solutions on both the signal processing and the networking fronts. In this presentation, we begin with an overview of channel characteristics, focusing on the major differences between underwater acoustic and terrestrial radio channels. We follow with a discussion of signal processing methods, briefly overviewing single-carrier broadband equalization used in an existing acoustic modem, and focusing on recent research results in multi-carrier signal detection on highly time-varying, Doppler-distorted channels. The performance of various techniques is illustrated through experimental results, which include transmissions over few kilometers in shallow water to hundreds of kilometers in deep water, at highest bit-rates demonstrated to date. We conclude by addressing the major issues involved in the design of underwater networks: the interplay between bandwidth and distance that impacts the notions of both relaying and cellular system design, and the high latency and packet loss that necessitate a dedicated design of the data-link layer.

Title: The “Cloud” to “Things” Continuum

Abstract: Back in 2011, we introduced the concept of a multi-tier cloud as part of the “Smart Applications on Virtualized Infrastructure (SAVI)” NSERC Strategic Network Project. SAVI extends the traditional cloud computing environment into a two-tier cloud including smart edges – small to moderate size data centers located close to the end-users (e.g., service provider premises), and massive scale data centers with abundant high-performance computing resources typically located in remote areas. We designed the smart edge as a converged infrastructure that uses virtualization, cloud computing and network softwarization principles to support multiple network protocols, customizable network services, and high-bandwidth low latency applications. Since then the concept of a multi-tier cloud has been widely adopted by telecom operators and in initiatives such as the Mobile Edge Computing (MEC). In the meantime, the advent of the Internet of Things (IoT) has seen an explosive growth in the number of connected devices generating a large variety of data in high volumes at high velocities. The unique set of requirements posed by the IoT data demands innovation in the information infrastructure with the objective of minimizing latency and conserving bandwidth resources. The multi-tier cloud computing model proposed in SAVI falls short in addressing the needs of the IoT applications, since, most  voluminous, heterogeneous and short-lived data will have to be processed and analyzed closer to IoT devices generating the data. Therefore, it is imperative that the future information infrastructure should incorporate more tiers (e.g., IoT gateways, customer premise equipments) into the multi-tier cloud to enable true at-scale end-to- end application orchestration. In this keynote, we will discuss the research challenges in realizing the future information infrastructure that should be massively distributed to achieve scalability; highly interoperable for seamless interaction between different enabling technologies; highly flexible for collecting, fusing, mining, and processing IoT data; and easily programmable for service orchestration and application-enablement.
