Title: Machine Learning in NextG Networks via Generative Adversarial Networks
Time: 16:30-17:00, Wednesday, February 22, 2023.

Due to the explosive growth of new users and new applications, it is expected that the wireless spectrum will need to be used in a dynamic fashion starting in the near future. This can be achieved by using the concept of cognitive radio, giving users access to the unused spectrum under dynamic spectrum access. It is generally accepted that conventional methods of cognitive radio will fall short of being able to handle the enormous demand for spectral resources, and therefore it is expected that techniques from artificial intelligence or machine learning will help provide dynamic control for spectrum sharing. The process of spectrum sharing begins with sensing the spectrum. Recently, a number of techniques for spectrum sensing employing machine learning have been introduced. In this talk, we discuss a machine learning approach known as generative adversarial networks towards this purpose. This particular approach is known to be very successful for anomaly detection in image processing. We alter performance criteria used in this set of networks from image processing applications to wireless and employ such networks for spectrum sensing, both in conventional and cooperative spectrum sensing. Initial results show the efficacy of this approach.

Title: 11:00-11:30, Tuesday, February 21, 2023
Time: Application-Oriented Scheduling for Optimizing Information Freshness in Wireless Networks

Motivated by the increasingly urgent demands for delivering fresh information, the age-of-information (AoI) has recently been introduced as an important metric for evaluating the timeliness performance of information update systems. Nevertheless, most of the existing studies are transmission-oriented, instead of directly characterizing the information freshness consumed at the application layer. In this talk, we introduce the concept of effective AoI (EAoI) to quantify the freshness of the information users utilize for decision-making. We consider a general request-response model, which captures both proactive information update and timely information delivery, for investigating the scheduling problem with respect to EAoI minimization. By decomposing the scheduling problem into multiple computationally tractable sub-problems, we propose request-aware scheduling policies for static and dynamic request models, respectively. The numerical results show that serving users requests proactively can reduce time-average EAoI in both scenarios.

Title: Unified View of IoT and CPS Security and Privacy
Time: 17:30-18:00, Monday, February 20, 2023

In this talk, I will present a unified view of Internet of Things (IoT) and Cyber Physical Systems (CPS) security and privacy. From the perspective of network architecture, IoT and CPS are similar. IoT devices and CPS field devices are controlled by particular types of communication modules, actuators and controllers. The modules and components have the networking functionality, connecting the devices to particular types of local area networks (LANs), which may use proprietary protocols. The LANs may be connected to the Internet so that administrators may access the devices remotely. We will use an air quality monitoring system and a smart plug system as IoT examples and smart building as an example CPS to demonstrate the unified view of IoT and CPS. There is a broad spectrum of IoT devices. We can divide them into two categories: powerful microprocessor based IoT systems that can run powerful operating systems (OSs) such as Linux; low-power microcontroller (MCU) based IoT systems that often do not run any OS or have limited OS support such as FreeRTOS. We will present an overview of MCU based IoT research from six aspects, including hardware, OS, software, networking, data and human, and discuss the trend of research in those fields.

Title: Distributed Software Applications Based on Mobile Cloud and Software-Defined Networks
Time: 11:30-12:00, Monday, February 20, 2023.

We consider an emerging class of challenging software applications called Real-Time Online Interactive Applications (ROIA). ROIA are networked applications connecting a potentially very high number of users who interact with the application and with each other in real time, i.e., a response to a user’s action happens virtually immediately. Typical representatives of ROIA are multiplayer online computer games, advanced simulation-based e-learning and serious gaming. All these applications are characterized by high performance and QoS requirements, such as: short response times to user inputs (about 0.1-1.5 s); frequent state updates (up to 100 Hz); large and frequently changing numbers of users in a single application instance (up to tens of thousands simultaneous users). This talk will address two challenging aspects of software for future Internet-based ROIA applications: a) using Mobile Cloud Computing for allowing high application performance when a ROIA application is accessed from multiple mobile devices, and b) managing dynamic QoS requirements of ROIA applications by employing the emerging technology of Software-Defined Networking (SDN).

Professor, Queen's University, Canada

Title: Anticipatory Radio Resource Management for 5G Networks and Beyond
Time: 16:30-17:00, Tuesday, February 21, 2023

5G wireless networks have brought about a technological transformation in modern societies by providing an ultra-reliable high-speed communications infrastructure that will serve billions of devices, machines and vehicles. These devices will contribute massive amounts of data that will need to be pipelined over future Beyond 5G (B5G) networks under the umbrella of future smart cities, connected autonomous cars, and IoT applications. The complexity of B5G networks will hence be unprecedented, due to the very diverse applications, ultra-low latency requirements for critical vehicle communication, growing demand for high positioning accuracy for location-based services, and dense, heterogeneous architectures.

In this talk, we address our efforts towards developing a smart management solution suite for future B5G networks based on innovative machine learning and big data analytics techniques. In particular, we discuss data-driven radio resource management functions that are mobility- and context-aware. In this domain we discuss the design of a predictive resource allocator that leverages individual user-level mobility information to opportunistically plan data transmissions in advance. We also discuss how to autoconfigure B5G mobility management network settings of cell selection and handover. The solutions will enable networks to be self-diagnosing and self-organizing and will enhance network capacity and user service while reducing capital and operating expenditures.

Title: Federated Learning With Efficiency and Privacy Considerations in Wireless Networks
Time: 11:00-11:30, Monday, February 20, 2023.

Centralized data collection and training in conventional machine learning (ML) algorithms have raised many concerns including privacy restrictions and communication cost due to massive amount of data transfer. Federated leaning (FL) exploits the rapidly growing computational capacity in small local devices and allows these devices to train ML models locally and only exchange the trained model parameters with the edge server. Through this, FL can greatly alleviate data privacy concern, reduce communication cost, and help build a scalable centralized ML model. FL methods offer a number of prominent advantages, including scalability and data privacy. On the other hand, a large-scale wireless network normally involves many heterogeneous devices with varying constraints and encounters very dynamic channel environments. This raises many challenges such as system heterogeneity, statistical heterogeneity, privacy and security, user scheduling, fairness in FL. This talk will present some of our recent research outcomes on model parameter transmission schemes and user scheduling strategies in FL that tackle these challenges. Techniques such as NOMA and over-the-air computation are introduced to achieve fast ML training. Model parameter compression and sparsification are further introduced to reduce the wireless communication cost. Moreover, model update-based aggregation is applied to defend against Byzantine attacks and individual client model initialization schemes are exploited to enhance privacy protection in FL.

Title: Smart Markers in a Blockchain: How to Release the Shackle of Single Branch
Time: 16:00-16:30, Wednesday, February 22, 2023.

The increasing complexity of modern hardware and software platform along with the imperative assurance on stability deems runtime verification of task fulfillment necessary in distributed systems. Distributing the burden of a central verification monitor to individual devices could improve the efficiency. It is possible to achieve decentralized runtime verification by incorporating some mechanisms of the blockchain technology for locating the accountability when error occurs. However, traditional blockchain technology disallows branching and hence does not support verification of tasks which involves multiway dependencies. In this talk, we introduce a novel approach of smart marker that can be included in a blockchain to enable multiway branching and merging in order to verify the fulfillment of tasks that involve one-to-many and many-to-one dependencies. The design of smart marker satisfies three requirements of recognizability, compatibility, and authenticability. We will also introduce how the smart markers can be used to enable an amendable and correctable blockchain.

Title: Stealthy Adversarial Machine Learning Attacks on RF Signal Classifiers: Algorithms and Countermeasures
Time: 16:00-16:30, Tuesday, February 21, 2023

Machine learning (ML) has recently been applied for the classification of radio frequency (RF) signals. One use case of interest relates to the discernment between different wireless protocols that operate over a shared and potentially contested spectrum. Although highly accurate classifiers have been developed for various wireless scenarios, research points to the vulnerability of such classifiers to adversarial machine learning (AML) attacks. In one such attack, a surrogate deep neural network (DNN) model is trained by the attacker to produce intelligently crafted low power “perturbations” that degrade the classification accuracy of the legitimate classifier. In this talk, I will first present several novel DNN protocol classifiers that our team designed for a shared spectrum environment. These classifiers performed quite well in both simulations and OTA experimentation, considering benign (non-adversarial) noise. I will then present several AML techniques that an attacker may use to generate low power perturbations. When combined with a legitimate signal, these perturbations are shown to uniformly degrade the classification accuracy, even in the very high SNR regime. Different attack models are studied, depending on how much information the attacker has about the defender’s classifier. These models range from a “white-box'” attack (attacker has full knowledge of the defender’s DNN, including its hyperparameters, its training dataset, and even the seeds used to train the network), to a “black-box” attack. Time permitting, I will discuss possible defense mechanisms as well as other research efforts related to detection of adversarial transmissions.

Title: Blockchain-enabled Edge Intelligence for 6G IoT
Time: 10:30-11:00, Tuesday, February 21, 2023

In the emerging 6G network, massive deployment of Internet of Things (IoT) devices to support smart environments such as smart cities, smart factories, smart offices and smart homes is anticipated. To deal with the enormous amount of data that will be generated by these devices and provide support to various applications, many of which have stringent latency requirements, use of multi-access edge computing (MEC) with artificial intelligence (AI), so called edge intelligence becomes critical. In very large networks, edge nodes may belong to different entities. Blockchain, a distributed ledger technology (DLT), has become a powerful structure to share data in a verifiable manner among edge nodes without them sharing trust. We present an overview of blockchain-enabled edge intelligence, and outline several challenges that researchers strive to address in this paradigm. The long time-delay of legacy blockchain consensus mechanisms make it difficult to meet the stringent latency requirement of 6G IoT. The security of distributed machine learning may be compromised by cyber-attacks. Performance of AI in 6G IoT may be constrained by the heterogeneity of IoT data. To address some of these challenges, we present innovative solutions for blockchain-enabled edge intelligence to minimize latency in blockchain-based edge training, defend against attacks on IoT data, and improve prediction accuracy of AI models in the presence of heterogeneous IoT data.

Title: Adapting Practical Byzantine Fault Tolerance (PBFT) for use with Blockchain-enable IoT systems
Time: 11:30-12:00, Wednesday, February 22, 2023

This work proposes Practical Byzantine Fault Tolerance (PBFT) ordering service needed for block formation in permissioned blockchain environments. Contrary to current PBFT implementations that only provide a single point of entry to the ordering service, we allow each ordering node to act as an entry point that proposes and conducts the consensus process of including new record in the distributed ledger. To ensure atomicity of record insertion in distributed ledger, we have developed a bandwidth reservation protocol that uses a modification of CSMA/CA protocol to regulate access to the broadcast medium formed by the P2P network of TCP connections between orderers. We have modeled record insertion service time in a cluster where ordering nodes have random position within Cartesian coordinate system. We have also modeled total request access time to the ledger which includes waiting time in the ordererÌs queue and record insertion time. These models are used to evaluate system performance under variable request rate ordering service, variable number of nodes and variable physical cluster dimensions. We also address cluster interconnections which can increase coverage and capacity of PBFT system.

Professor, University of Ottawa, Canada

Title: Towards Automating Network Operation Centers with AI
Time: 10:30-11:00, Wednesday, February 22, 2023

Network Operation Centers (NOC) are responsible for monitoring their network’s health and performing service assurance by meeting the customers’ service level agreements while reducing operational expenditures. In today’s NOCs, most of the said operations are either done manually or, for the simplest cases, with previously prepared expert rules. A team of NOC technicians works 24/7 and, to handle non-trivial issues, relies on specialized support teams organized by technology domains, themselves relying on vendors’ technical support on call. But this mostly manual model is getting increasingly expensive and inefficient as networks become larger and more complex. Automating NOC operations would be a big help, but automation attempts with explicit rules have not been very successful due to the intrinsic difficulty of defining rules that work reliably in such complex systems. In this talk, we describe our pilot study with Ciena Corp in using Artifical Intelligence to automate both network state detection and action recommendation, achieving up to 99% and 97% accuracy, respectively.

Shervin Shirmohammadi (M'04, SM'04, F'17) received his Ph.D. in Electrical Engineering in 2000 from the University of Ottawa, Canada, and after spending 3 years in the industry as a senior architect and project manager, joined as Assistant Professor the same University, where since 2012 he has been a Full Professor with the School of Electrical Engineering and Computer Science.

AI techniques are expected to enhance cybersecurity by assisting human system managers with automated monitoring, analysis, and responses to adversarial attacks. Conversely, it is essential to guard AI technologies from unintended uses and hostile exploitation by leveraging cybersecurity practices. The interplay between AI/machine learning, and cybersecurity introduces new opportunities and challenges in the security of AI as well as AI for cybersecurity. In this talk, I will present my recent research on AI for cybersecurity and the security of AI. First, I will introduce my research on AI for cybersecurity, i.e., real-time machine learning for quickest event (threat/intrusion/vulnerability…) detection. Next, I will present my research on the security of AI, i.e., coverage-driven testing and evaluation of deep learning systems. I will conclude my presentation with my ongoing research on neurosymbolic AI.

Title: Wave-Controlled Reconfigurable Intelligent Surfaces
Time: 10:00-10:30, Tuesday, February 21, 2023

Reconfigurable Intelligent Surfaces (RIS) are able to beneficially modify the radio wave propagation environment by electronically controlling the behavior of a large number of small reactive elements. Very large RIS with many controllable elements would in principle require numerous electronic connections that complicate the design and layout of the physical device. In many scenarios, especially when the RIS elements are closely spaced (e.g., less than one-half wavelength), coupling prevents achieving arbitrary element phase responses, and besides the desired element responses are likely to be highly correlated. Thus, the number of effective degrees of freedom offered by the RIS may be significantly less than the number of its elements. To exploit this fact, we propose a waveguide-based control that simplifies the design and provides an efficient parameterization of the RIS degrees of freedom in terms of the modes of a waveguide signal that propagates across the RIS. Examples will be given showing the performance of such a method compared with methods that attempt to arbitrarily control each RIS element.

Title: Generative Steganography via Live Commenting on Streaming Videos
Time: 17:00-17:30, Tuesday, February 21, 2023

I'll present a novel generative steganographic method using both texts and videos as carriers. Live commenting on videos played on video streaming websites is a popular feature, especially among younger viewers. We show that this feature, together with the underlying videos, can be exploited into a covert channel to conceal secrete information. In particular, given a secrete message, I'll demonstrate how to select an appropriate video and use a random reversible matrix to select appropriate video frames to embed and extract secret messages. We then use a neural model to generate appropriate comments to be posted on the selected video frames. The model consists of a residual network encoder to extract image features of the selected video frames and an LSTM decoder to generate comments that look normal to the general viewers. We train the model using a dataset we collected from popular video streaming websites, which consists of live comments posted on videos and the underlying videos. We show that, through experiments, the generated comments posted on selected video frames are imperceptible. Moreover, our method is able to conceal any message of a reasonable length by selecting an appropriate video without losing concealability.

Title: Deep autoencoders for analysis of single-cell RNA sequencing data
Time: 17:30-18:00, Monday, February 20, 2023

Clustering is a classical unsupervised learning approach. Clustering analysis has been conducted routinely in many fields, including single-cell RNA sequencing (scRNA-seq) studies mor recently. Numerous methods have been designed for clustering scRNA-seq data. However, most existing clustering methods for scRNA-seq have one or more of the following limitations: (1) ignore the characteristics of scRNA-seq data; (1) fail to exploit prior information for optimizing clustering performance; and (3) could not filter out irrelevant genes while conducting clustering. In this talk, I will introduce model-based deep autoencoders to address these issues. Extensive experiments on both simulated and real datasets demonstrate that the proposed methods can boost clustering performance significantly and result in biologically meaningful clusters.

Dr. Wei is currently a professor of computer science and statistics (joint appointment) with the New Jersey Institute of Technology. He is also an adjunct professor at the University of Pennsylvania.

Title: DCWiz: Transforming Data Center Operations and Management with AI
Time: 10:00-10:30, Wednesday, February 22, 2023

Data center, dedicated space to house computer systems and associated components, plays an important role in propelling digital transformation globally, especially in the presence of a global pandemic (e.g., COVID-19). The resulted extensive use of services such as cloud, big data, IoT and artificial intelligence is prompting DC operators to consolidate high-performance mission critical IT infrastructure in hyper-scale data centers. In practice, data centers are managed and optimized towards two operational objectives: 1) business resilience, serving to evaluate the commercial impact of service disruption, and 2) operations sustainability, serving to evaluate the cost of providing services. AI solutions, made popular by Google DeepMind, have been touted with great potential to optimize the aforementioned operational metrics. However, adopting AI techniques for data center operations and management (O&M) faces substantial challenges due to data scarcity and risk-averse mindset. In this talk, we present DCWiz, a transformative industrial AI solution that integrates an industry-grade digital twin with emerging AI techniques to digitalize, optimize and automate data center O&M for operational excellence. Specifically, DCWiz leverages advanced AI techniques (e.g., deep reinforcement learning and generative adversarial network) to train an industry-grade digital twin for any physical data center, in terms of data accuracy, and deploy the digital twin as a pivotal module to provide descriptive, predictive and prescriptive AI for DC O&M. We delve into two use cases, namely hot-spot management and PUE optimization, to show that DCWiz would potentially lead to 30% of cooling cost saving in tropical environments. We further share several commercial trials with Alibaba, Singapore National Supercomputing Center (NSCC), Singapore, each of which represents different applications of the DCWiz solution. The trial results demonstrate the effectiveness of our DCWiz solution in improving manageability, reducing cost and mitigating operational risks for mission-critical data centers.

Title: What Color is Your Internet? And Can We Make it Green?
Time: 15:00-15:30, Wednesday, February 22, 2023

Reducing energy consumption - and especially carbon emissions - is one of the most important challenges facing humankind. ICT are a powerful tool to reduce emissions, as they offer alternatives to activities that are costly in energy: video streaming saves energy vs driving to a movie theater, for instance.

Still, the carbon footprint of networking has been growing, despite better energy efficiency per transmitted bit, due to the sheer growth in Internet usage and traffic. The information and communication technology (ICT) sector is estimated to currently create 2.7% of all global CO2 emissions and is expected to significantly increase its power consumption by 2030.

As such, it is important to offer new mechanisms to reduce the energy footprint of networks. In this talk, we present some of the challenges for green networking, with a discussion of different levels in the network where to apply energy considerations. We discuss the potential for standardization within IETF. We also present a framework to include energy consideration into the management plane of a network; we apply this framework to optimize the network topology so as to minimize the energy spending while at the same time providing a satisfactory Quality of Experience (QoE) to the end users.

Title: Time-space synchronized digital twin for B5G managed network
Time: 10:00-10:30, Monday, February 20, 2023

Beyond 5G, ultra-reliable and low latency communication (URLLC) is a key technology. This paper describes ultra-multi-wavelength parallel optical paths and hollow-core fiber to realize the ultimate low latency path. Once ultra-low latency is realized, cyber-physical systems will not only have low latency in the access system, but also become sophisticated, realizing a spatially-synchronized cyberspace that is synchronized in the area, i.e., spatially synchronized in time and space. In other words, events occurring in the spatially spread physical space can be monitored and controlled centrally like a diorama. This is called a time-space synchronized digital twin. This paper describes two applications, including experiments: the first is a predictive digital twin, in which technology to predict and control the near future is applied to self-driving cars; the second is a security network in which sensors distributed in a region can be centrally managed using URLLC paths. These technologies will be key to a reliable and smart Beyond 5G society.

Title: 5G NR-Light at Millimeter Waves: Design Guidelines for Mid-Market IoT Use Cases
Time: 13:30-14:00, Wednesday, February 22, 2023

5th generation (5G) systems have been designed with three main objectives in mind: increasing throughput, reducing latency, and enabling reliable communications. To meet these (often conflicting) constraints, the 3GPP released a set of specifications for 5G NR, one of the main innovations being the support for communications in the millimeter wave (mmWave) bands. However, how to implement lower complexity, energy efficient, mid-market Internet of Things (IoT) applications is still an on-going investigation, currently led by the 3GPP which is extending the NR standard with NR-Light specifications to support devices with reduced capabilities (REDCAP). While REDCAP devices may also operate at mmWaves to improve the network performance, hardware/software simplifications are needed to support balanced and mixed requirements compared to 5G NR systems. In this context, contributions of this paper are threefold. First, we present some NR-Light use cases for which the support of the mmWave bands is desirable. Second, we describe how 5G NR can be simplified to achieve NR-Light requirements and expectations. Finally, we evaluate via simulation the performance of REDCAP devices operating at mmWaves in an industrial IoT setup, in terms of cost and complexity, throughput, and latency.
