Title: Achieving Optimum Received Power in the Smallest Number of Steps for Discrete-Phase RISs
Time: 10:30am-11:00am, Tuesday, February 20, 2024

The problem of optimizing discrete phases in a reconfigurable intelligent surface (RIS) to maximize the received power at a user equipment will be addressed. Necessary and sufficient conditions to achieve this maximization will be given. These conditions are employed in an algorithm to achieve the maximization. New versions of the algorithm will be presented that are proven to achieve convergence in N or fewer steps whether the direct link is completely blocked or not, where N is the number of the RIS elements, whereas previously published results achieve this in KN or 2N number of steps where K is the number of discrete phases. Thus, for a discrete-phase RIS, the techniques to be presented in this talk achieve the optimum received power in the smallest number of steps published in the literature. In addition, in each of those N steps, the techniques to be presented in this talk determine only one or a small number of phase shifts with a simple elementwise update rule, which result in a substantial reduction of computation time, as compared to the algorithms in the literature. As a secondary result, we will define the uniform polar quantization (UPQ) algorithm. We will discuss its performance and complexity in comparison to the optimum algorithms we will present.

Title: To Find the Supremacy of Machine Learning in Wireless Network Optimization
Time: 16:00pm-16:30pm, Wednesday, February 21, 2024

With the superior capability of discovering intricate structure of large data sets, machine learning has been widely applied in various areas including wireless networking. Modern wireless networks have seen a tremendous increase in size and complexity, where the capacity optimization urgently calls for an innovative and efficient computing paradigm. This talk shares our recent studies on how to exploit deep learning for significant performance gain in wireless network optimization. We start with a discussion about our vision of the supremacy of machine learning (ML), trying to fundamentally understand where and how the ML based approaches show advantages versus the conventional modeling-based approaches. We then demonstrate that ML has the unique capability to identify latent structure information, embedded in historical solved optimization instances but invisible to traditional algorithms, leading to new algorithms that can greatly mitigate the computation overhead while maintain a good performance. New ML techniques have been developed to extract and leverage the structure information from three perspectives: topology-level, algorithm-level, and application-level.

Invited Talk Title: Building a Digital Power Computer for Green 6G
Time: 10:00am-10:30am, Thursday, February 22, 2024

In the upcoming era of 6G, the number of base stations, edge computing nodes and data centers is believed to be multifold, imposing a serious challenge on the network deployment and operation, especially on its how to power 6G networks in a green and sustainable way. With ever-increasing penetration rate of renewable energy in power grids, the traditional analog ICT powering systems cannot meet rigorous requirements on power feeding systems posed by 6G network application scenarios. Thanks to the recent breakthrough of power electronics semiconductors, such as power MOSFET, SiC and GaN with their outstanding material properties, it becomes feasible to carry out digital power signal processing at high switching speed, high voltage, and feverish temperature. By building a new “digital power computer” using highly efficient low voltage power switches, traditional analog power feeding systems can be transformed into digital systems, turning into a new type of network devices. In this talk, we will propose and describe the basic concept of digital power computing and the system architecture of digital power computer. Results of experiments and real-world applications show the effectiveness and efficiency of digital power computer, which offering a promising disruptive path to sustainable power feeding for green 6G.

Invited Talk Title: GPS Spoofing on Individual Drones and Drone Swarms
Time: 10:30am-11:00am, Thursday, February 22, 2024

We will first present an accurate GPS spoofing attack on individual drones, and then discuss advanced swarm spoofing problems. First, while many existing spoofing methods can disrupt drone invasions, they cannot accurately guide a drone to a desired location. To address this issue, we propose the Drone Position Manipulation (DPM) attack to exploit the path-following navigation algorithms to accurately redirect an invading drone to a desired location, by carefully crafting the spoofed guidance inputs. We evaluate the attack on the Software-in-the-loop (SITL) module of ArduPilot system to show its effectiveness.

Second, while most such spoofing attacks focus on a single receiver, we investigate the impacts of a single spoofer on multiple receivers. Our analysis shows that, using a single spoofer, multiple receivers at different locations in a spoofing area will see the same location reading. We conduct real-world experiments to validate our analysis. Furthermore, because very little systematic research on swarming spoofing has been conducted, we develop a basic model to show the theoretical capabilities and limitations of swarm spoofing. We then broaden the basic model to explore the theoretical capabilities and limitations of swarm spoofing under various assumptions and constraints. Although this work focuses on the GPS system, the research can be easily applied to other GNSSs, such as Galileo or GLONASS.

Title: Building Automation System Security
Time: 10:00am-10:30am, Tuesday, February 20, 2024

Building Automation Systems (BASs) are seeing increased usage in modern society due to the plethora of benefits they provide such as automation for climate control, HVAC systems, entry systems, and lighting controls. Many BASs in use are outdated and suffer from numerous vulnerabilities that stem from the design of the underlying BAS protocol. In this talk, we provide a comprehensive, up-to-date survey on BASs and attacks against seven BAS protocols including BACnet, EnOcean, KNX, LonWorks, Modbus, ZigBee, and Z-Wave. Holistic studies of secure BAS protocols will also be presented, covering BACnet Secure Connect, KNX Data Secure, KNX/IP Secure, ModBus/TCP Security, EnOcean High Security and Z-Wave Plus. LonWorks and ZigBee do not have security extensions. We point out how these security protocols improve the security of the BAS and what issues remain. A case study is provided which describes a real-world BAS and showcases its vulnerabilities as well as recommendations for improving the security of it. We seek to raise awareness to those in academia and industry as well as highlight open problems within BAS security.

Title: High-Level Development of Networked Applications with RT QoS Requirements
Time: 11:30am-12:00pm, Tuesday, February 20, 2024

Real-Time Online Interactive Applications (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 developing such 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 technology of Software-Defined Networking (SDN).

Invited Talk Title: WiSegRT: Dataset for Site-Specific Indoor Radio Propagation Modeling with 3D Segmentation and Differentiable Ray-Tracing
Time: 10:00am-10:30am, Wednesday, February 21, 2024

The accurate modeling of indoor radio propagation is crucial for localization, monitoring, and device coordination, yet remains a formidable challenge, due to the complex nature of indoor environments where radio can propagate along hundreds of paths. These paths are resulted from the room layout, furniture, appliances and even small objects like a glass cup. They are also influenced by the object material and surface roughness. Advanced machine learning (ML) techniques have the potential to take such non-linear and hard-to-model factors into consideration. However, extensive and fine-grained datasets are urgently required. This paper presents WiSegRT1, an open-source dataset for indoor radio propagation modeling. Generated by a differentiable ray tracer within the segmented 3-dimensional (3D) indoor environments, WiSegRT provides site-specific channel impulse responses for each grid point relative to the given transmitter location. We expect WiSegRT to support a wide-range of applications, such as ML-based channel prediction, accurate indoor localization, radio-based object detection, wireless digital twin, and more.

Title: Reliably Putting Their Heads Together: Application of Probabilistic Blockchain in Multi-Agent Decision-Making Systems
Time: 16:30pm-17:00pm, Wednesday, February 21, 2024

Designed as a distributed data storage system, blockchain employs a consensus mechanism to validate the addition of new data blocks while saving the need for mediation by a centralized server. However, when the blockchain technology is applied in decision-making applications, the consensus mechanism requires the decision to be deterministic, which will ignore different recommendations made by multiple agents and may put the computing system at the risk of missing valid insights. In this talk, we will first introduce the concept of probabilistic blockchain and compare the strengths and weaknesses of some existing approaches. Then, we introduce our solution called SMARPchain, which is a paradigm of reputational probabilistic blockchain based on the incorporation of smart markers. The distinguishing characteristic of SMARPchain is that it enables multiway branching which allows the result produced by each agent to be kept on the blockchain as a branchchain. Moreover, SMARPchain computes a probabilistic score on each branchchain based on the associated agent’s reputation to help the decision maker reach an informed decision. Our evaluation results show that SMARPchain will enhance the security and robustness of multi-agent decision-making systems with acceptable overhead.

Invited Talk Title: Synthesizing RF Coverage Maps for Wireless Systems Using Generative AI
Time: 16:00pm-16:30pm, Tuesday, February 20, 2024

Network planning, spectrum-access coordination, and protocol adaptation can be greatly facilitated using RF maps, which can be obtained for various bands of interest, including the heavily congested mid-band spectrum as well as millimeter-wave (mmWave) and sub-THz bands. However, acquiring such maps through site surveys is quite labor-intensive and sometimes not feasible. One solution is to use ray-tracing simulations, which incur significant computational overhead and may necessitate simplifications that impact the accuracy of this approach. As a computationally efficient alternative, we advocate the use of generative adversarial networks (GANs) for synthesizing RF coverage maps. First, we introduce a GAN-based approach for RF map Estimation and Categorization through Unsupervised Attribute Extraction (RecuGAN). RecuGAN incorporates various attributes to capture the diversity of the RF environment. We show that once trained, a RecuGAN has the ability to generate RF maps with specific attribute values. Next, we present a semantics-based GAN for synthesis of RF maps with attribute values not previously seen in the training set. We refer to such maps as “extrapolated maps.” They include, for example, scenarios where the GAN is trained on RF maps of one environment (e.g., a given floor plan) but used to synthesize RF maps for another environment. Other aspects of extrapolation include antenna array size, transmitter location, and center frequency. Comparison between AI-generated RF maps and their simulated/measured counterparts demonstrate the effectiveness of the proposed approaches in synthesizing maps for different indoor environments and parameter settings.

Invited Talk Title: Reliable Communications for Future Aviation
Time: 17:00pm-17:30pm, Wednesday, February 21, 2024

Rapid growth in aviation will require advances in air-ground and air-air communications, navigation, and surveillance (CNS). Projects like NASA’s Advanced Air Mobility (AAM), which is aimed at the transportation of both cargo and people in low-altitude flights in and around urban areas, require extremely high-reliability links, often with low latencies. In this presentation, we provide background on aviation trends and existing requirements, outline future plans, then focus on reliable air-ground (AG) communications. For this we discuss both intrinsic challenges such as wireless channel impairments and spectrum constraints, as well as extrinsic challenges such as interference, both unintentional and intentional (i.e., jamming). After a brief review of reliability techniques at the network and data link layers, we direct attention to the physical layer, and discuss in some detail AG channel effects, then transmission security (transec) and anti-jam (AJ) techniques. We illustrate that by taking an adversary’s perspective we can improve link design and operation. The talk will conclude with comments on the future potential of machine learning and artificial intelligence, along with other areas for future work.

Invited Talk Title: Deploying Proof of Stake and Delegated Proof of Stake consensus protocols for blockchains in IoT environments.
Time: 11:00am-11:30am, Wednesday, February 21, 2024

Blockchain ledgers are being increasingly used in Internet of Things (IoT) and Internet of Vehicles (IoV) applications. However, Proof of Work consensus is unsuitable in an IoV setting, which is why other paradigms need to be investigated. In this talk we discuss Proof of Stake (PoS) and Delegated Proof of Stake (DPoS) techniques in IoT environment. We integrate PoS and DPoS consensus technique with multiple entry Practical Byzantine Fault Tolerance voting in a permissioned blockchain network. We introduce several PoS/DPoS classes based on combination of initial stake and truthfulness of voting. For DPoS we introduce concept of virtual stake which is used to elect leaders and witnesses based on their behavior. Using a Semi Markov Process-based model, we derive the probability of reaching consensus and highlight the impact of the populations of individual stake/priority classes on achieving consensus. We also describe a differentiated medium access approach similar to Enhanced Distribution Function (EDCA). We also discuss quantum implementation of PoS and DPoS consensus algorithms for IoT blockchains.

Invited Talk Title: Service Deployment with Priority Control in Network Function Virtualization
Time: 11:00am-11:30am, Tuesday, February 20, 2024

Network function virtualization (NFV) makes deploying network services more flexible with virtual network functions (VNFs). Network resources in an NFV environment can be provisioned elastically to handle heterogeneous services.

Invited Talk Title: Improving Network Operation Center Automation with Reinforcement Learning
Time: 11:00am-11:30am, Thursday, February 22, 2024

Today’s Network Operation Centres (NOC) consist of teams of network professionals responsible for monitoring and taking actions for their network’s health. Most of these NOC actions are relatively complex and executed manually; only the simplest tasks can be automated with rules-based software. But today’s networks are getting larger and more complex. Therefore, deciding what action to take in the face of non-trivial problems has essentially become an art that depends on collective human intelligence of NOC technicians, specialized support teams organized by technology domains, and vendors’ technical support. This model is getting increasingly expensive and inefficient; hence, the automation of all or at least some NOC tasks is now considered a desirable step towards autonomous and self-healing networks. In this talk, we describe the design of an autonomous NOC that can recommend or take actions that lead to better results than those achieved by human expert rules. Specifically, we use Reinforcement Learning and train it with expert rules, and let it explore actions by itself. We then show that it can learn new and more efficient strategies that outperform expert rules.

Invited Talk Title: Participant Selection and Learning Scheduling for Federated Edge Learning
Time: 16:30pm-17:00pm, Thursday, February 22, 2024

Abstract: Edge computing and federated learning (FL) have gained popularity since they provide a promising edge learning framework that mitigates the limitations of long latency, high cost, and privacy concerns in cloud-based centralized learning. While most existing works on federated edge learning focus on optimizing the training of one shared global model in edge systems, the concurrent training of multiple FL models from different applications in a shared edge cloud can lead to edge resource competition and affect the training performance of each model. Hence, in this talk, I will present our recent works in addressing this challenge by proposing optimization algorithms to jointly select FL participants and learning rates or topologies for each model, with an aim of minimizing the total training cost. Particularly, I will first introduce a multi-stage optimization framework that allows FL models to select their participants and learning rates or learning topologies. Then, I will describe a new Hybrid Quantum-Classical Benders’ Decomposition algorithm to tackle the joint participant selection and learning scheduling problem using both quantum and classical computing. Our methods improve resource competition and load balancing of multi-model FL in shared edge clouds. Finally, I will summarize the talk with discussions about future directions in federated edge learning.

Invited Talk Title: Time-space synchronized digital twin application for URLLC using newly structured Hollow-Core Fiber and its open innovation field
Time: 11:30am-12:00pm, Wednesday, February 21, 2024

Beyond 5G, ultra-reliable and low latency communication (URLLC) is a key technology.

This paper describes newly structured fiber called Hollow-Core Fiber (HCF) and its applications. High power optical signals can be transmitted through the air core without degradation due to optical non-linearity. The transmission speed is close to the speed of light because the effective index of the HCF is about 1.

So that we propose ultra-multi-wavelength parallel optical paths with hollow-core fiber to realize the ultimate low latency path. The ultra-low latency network in cyber-physical systems enables the cyberspace to be not only accessed with low latency but also spatially and temporally synchronized with the physical space in an area. This is called a time-space synchronized digital twin. This is called a time-space synchronized digital twin. This paper also describes other new futures such as power over fiber (PWoF) and analogue radio over fiber (ARoF) tested in the Keio university future optical network open research center. These technologies will be key to a reliable and smart Beyond 5G society.

Invited Talk Title: Robust and Privacy-Preserving Federated Learning: Cryptographic Perspectives and Wireless Perspectives
Time: 17:00pm-17:30pm, Tuesday, February 20, 2024

Federated Learning (FL) has been a trendy privacy-enhancing technique in distributed systems. In FL, data remains at local devices during the training process. However, data privacy can still be breached in light of data reconstricution attacks or membership inference attacks. For better privacy protection, privacy-protection FL (PPFL) is desired in which local parameters are encrypted or obfuscated before being uploaded. However, PPFL makes model poisoning attacks more convenient. To achieve PPFL and FL robustness simultaneously is a challenge. This talk delves into this problem with both cryptographic approaches and wireless approaches.

Shucheng Yu's current research interests include information security, applied cryptography, wireless networking and sensing, distributed trust, and applied machine learning. He is also interested in practical security and privacy in IoT systems.

He is the recipient of the Test of Time Paper Award of IEEE Infocom 2020 for his research on cloud data security. He directs the AISecLab research cluster of the ECE department at Stevens. He is a Fellow of IEEE.

Title: On the Simulation and Evaluation of Non-Terrestrial Networks
Time: 11:30am-12:00pm, Thursday, February 22, 2024

The 5th generation (5G) of mobile networks has landed in the commercial area, and the research community is now exploring new functionalities for 6th generation (6G) networks, for example non-terrestrial networks (NTNs) via space/air nodes such as Unmanned Aerial Vehicles (UAVs), High Altitude Platforms (HAPs) or satellites. While research in this field has been mostly theoretical in nature so far, new simulation platforms have been recently released to numerically evaluate the performance of this paradigm. In particular, in this talk we present a new open-source end-to-end module for ns-3 that implements the NTN physical layer (specifically channel and antenna models) based on 3GPP specifications. However, NTN comes with critical constraints, especially in terms of latency, coverage, and mobility, that may require a massive re-design of the 5G protocol stack. Therefore, we will also discuss current open issues for the proper simulation and evaluation of NTN to stimulate further research in this domain.
