From 2011 to 2016 the NSERC Strategic Network for Smart Applications on Virtual Infrastructures (SAVI) investigated the convergence of computing, networking, and sensing to create an agile platform for smart applications. We introduce SAVI’s multitier computing cloud that converges computing, SDN and sensing, and we describe the testbed that was deployed across Canada and federated with the U.S. We discuss use cases that are operational on SAVI including: service chaining, testbed-wide orchestration, intrusion-detection and protection using NFV, multilayer monitoring and modeling using machine learning, and a live intelligent transportation dashboard for the Greater Toronto Area

Talk #3: Cognitive Electromagnetic Spectrum Operations: Emerging Trends and Technologies

Abstract: Electromagnetic spectrum operations (EMSO; a major component of CEMA, Cyber Electromagnetic Activities) are fundamental to a variety of defense and public security contexts. Forward-thinking roadmaps have highlighted the need to extend this to cognitive EMSO on dynamic land/water/air/space platforms.

Current solutions for CEMA — all based on COTS technologies — are lacking in several respects. Higher performance solutions have unfavorable size, weight and power (SWaP) characteristics, and low agility; the lower-end offers questionable quality of measurement with low flexibility. Additionally, the lack of sufficient edge computing to handle the high loads of radio signal processing often preclude aggressive real-time online sensing.

This talk will present a solution for RF situational awareness that disruptively surmounts these issues in all respects. Rather than employ COTS technologies with poor SWaP and mediocre performance, we present a custom integrated circuit (IC) that enables ultra-low SWaP with high-performance. Central to the solution is the integration of significant on-chip computing resources that enable processing of high-bandwidth RF data directly at the source. The lack of a hardened algorithmic processing chain enables flexible and rapid reconfiguration of the sensor-actuator personality. On-chip computation further facilitates a very agile loop from the high-level algorithmic processing to the low-level RF, analog and digital front ends.

We will also discuss how this uniquely Canadian technology aligns with and enables advanced defense applications.

Beyond this, they have developed real-time RF propagation and data fusion tools, and software suites for advanced cognitive radio sensing and communications applications. He also leads a number of strategic initiatives to anticipate and execute on the RF situational awareness requirements posed by next-generation civilian and defence roadmaps pertaining to electromagnetic spectrum operations.

Abstract: We address sparse signal, i.e. image recovery in a Bayesian estimation framework where sparsity is enforced on reconstruction coefficients via probabilistic priors. In particular, we focus on the popular spike and slab prior which is considered the gold standard in the statistics literature. The optimization problem resulting from this model has broad applicability in recovery, regression and classification problems and is known to be a hard non-convex problem whose existing solutions involve simplifying assumptions and/or relaxations. We propose an approach called Iterative Convex Refinement (ICR) that aims to solve the aforementioned optimization problem directly allowing for greater generality in the sparse structure. Essentially, ICR solves a sequence of convex optimization problems such that sequence of solutions converges to a sub-optimal solution of the original hard optimization problem. Applications will be considered in image classification as well as image reconstruction.

Finding Common Ground: Channel Analysis and Receiver Models for Diffusive Molecular Communication

Abstract: Diffusive molecular communication (MC) is a promising strategy for the transfer of information in synthetic networks of “small” devices (on the scale of living cells or smaller). If such devices could communicate, then it would potentially enable applications such as cooperative diagnostics in medicine, bottom-up fabrication in manufacturing, and sensitive environmental monitoring. Results in this domain can also contribute to our understanding of diffusive signaling in natural biological systems and the diseases that develop when the signaling malfunctions. Diffusion based MC for synthetic networks faces challenges such as infinite inter-symbol interference and constrained computational resources in “simple” transceivers, but also interesting opportunities such as the possibility to manipulate the channel response via chemical means. This presentation highlights our contributions to the modeling and analysis of diffusion-based MC systems, including derivations of the channel impulse response and the development of simulation tools. We describe our recent work to find a unifying analytical framework for the two most common but distinct receiver models, where molecules are either absorbed by the receiver surface or passively diffuse through it. We also discuss some of our on-going work to bridge the gap between the realism of existing analytical models and the availability of relevant experimental data.

What can physical-layer security do for you?

Abstract: The conventional approach to ensure confidential communications relies on public-key/private-key protocols, which operate on error-free data after the physical-layer has been established. While the effectiveness of this approach in traditional settings is unquestionable, new systems are emerging where treating confidentiality as an overlay feature of top of reliability may not be the most appropriate solution. In particular, modern wireless networks, which comprise heterogeneous nodes with limited computational and energy resources, would benefit from the integration by design of confidentiality in the physical-layer, especially if this can be done in a cost-effective way. In this talk, we will provide a perspective on what physical-layer security can realistically do for wireless communication systems. Our objective will be not only to review the challenges faced by physical-layer security but also to present some of our recent research activities in the areas of information theory, coding theory, and wireless systems that suggest potential solutions to overcome these challenges.

Abstract: Cloud radio access network (C-RAN) is an emerging wireless cellullar architecture in which the base-stations (BSs) take advantage of high-capacity backhaul links to upload signal processing and computation to a cloud-computing based central processor. The C-RAN architecture offers an enabling platform for the centralized joint encoding and joint decoding of user messages and a capability for intercell interference mitigation across the BSs. In this talk, we address the capacity analysis and optimization technique for C-RAN while specifically taking into account the finite capacity constraint on the backhaul links. In the uplink, the C-RAN architecture can be modeled as a multiple-access relay channel. We analyze a compress-and-forward scheme in which the BSs quantize the received signals and send the quantized signals to the central processor using Wyner–Ziv coding. We also propose a successive convex optimization approach for optimizing the quantization noise covariance matrix. In the downlink, the C-RAN architecture can be modeled as a broadcast relay channel. We compare the message-sharing strategy versus compression-based strategy for this setting, and show how compressive sensing and weighted minimum mean-squared error (WMMSE) techniques can be used to solve a network utility maximization problem involving joint user scheduling, BS clustering and beamforming in a user-centric message-sharing C-RAN design.
