Title: Holographic Radio: A New Paradigm for Ultra-Massive MIMO

Time and Date: July 22, 2022, at 9:00AM ET

Presenter:  Professor  Lingyang Song, Peking University, China

Venue: https://zoom.us/j/9172542706 (Password: 4Zn7xZ)

Abstract: To enable a ubiquitous intelligent information network, the forthcoming sixth generation (6G) wireless communications are expected to provide revolutionary mobile connectivity and high-throughput data services through ultra-massive multiple input multiple output (MIMO). Widely-utilized phased arrays relying on costly components make the implementation of ultra-massive MIMO in practice become prohibitive from both cost and power consumption perspectives. The recent developed reconfigurable holographic surfaces (RHSs) composing of densely packing sub-wavelength metamaterial elements can achieve holographic beamforming without costly hardware components. By leveraging the holographic principle, the RHS serves as an ultra-thin and lightweight surface antenna integrated with the transceiver, thereby providing a promising alternative to phased arrays. In this talk, we will first provide a basic introduction of RHSs. We then introduce the unique features of RHSs which enables ultra-massive MIMO for both communication and sensing, in a comprehensive way. Related design, analysis, optimization, and signal processing techniques will be presented along with typical RHS-based applications for wireless communications. The implementation issues along with our developed prototypes and experiments will also be discussed.

Title: AI and Privacy in Collaborative Spectrum Sharing: Perspectives from the Spectrum Collaboration Challenge and Beyond

Abstract: Dynamic spectrum access has the potential to greatly improve the utilization of the radio spectrum over existing static allocation techniques. Systems like Citizens Broadband Radio Service (CBRS) are first steps in realizing this vision. However, CBRS is still very limited in its need for centralized coordination (via spectrum access systems) and the potentially long delays (up to 24 hours) in issuing new spectrum grants. In the DARPA Spectrum Collaboration Challenge (SC2), teams performed distributed and collaborative spectrum sharing with spectrum usage patterns changing on time-scales of seconds. This was facilitated by the exchange of information via a collaboration channel, including teams’ usage of spectrum across time and space, as well as information on teams’ performance in delivering traffic. Although this data greatly helps in developing strategies for spectrum use, it also presents risks from both the disclosure of private information and from the potential for manipulating systems’ actions through misreporting. In this talk, I will discuss our experiences in collaborative spectrum sharing during the SC2, our work on applying ML to these problems, and our work on providing privacy in distributed spectrum sensing. I will conclude with a discussion of open problems in these areas.

Title: Algorithmic Sensing in the Age of Artificial Intelligence

Time and Date: Apr. 8, 2022, at 9:00 am ET

Presenter:  Professor  Jun Luo, Nanyang Technological University, Singapore

Venue:  https://zoom.us/j/9172542706 (Password: 4Zn7xZ)

Abstract: Promoted by the increasing compactness of embedded sensors and tremendous progress in artificial intelligence, algorithmic sensing is gaining momentum as it has the potential to push the limit of physical sensors. However, realizing the promises of algorithmic sensing can be highly non-trivial, as specific machine/deep learning techniques have to be fine-tuned to suit diversified sensing modalities, as opposed to direct feature extraction and classification largely ignoring the distinctive physics of respective sensors. In this talk, we take Radio Frequency (RF) sensing as a representative example. We first explain the basic idea of RF-based algorithmic sensing, then we present a unified framework to prepare RF sensing data for deep analytics. Building upon this framework, we further explain the peculiarity of RF sensing data (against, e.g., conventional image data) and present our approaches in designing deep interpreted RF sensing, leveraging our latest developments on a (software-defined sensing) platform, along with corresponding applications and products as instances.

Title: Machine Learning Classification of RF Signals over Congested and Contested Spectrum: Algorithms and Experimentation

Date and Time: February 23, 2022 at 11AM ET

Registration Process: Please register at https://tinyurl.com/zkvvsjav

Abstract: 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.

Abstract: Embedding sensing and communication capabilities seamlessly into ambient environment is a long-term aspiration of the Internet of Things (IoT). Smart surfaces, with conformable shape, thin form factors, and ease of fabrication, can potentially materialize the vision of intelligent and connected things. In this talk, I will present the design of passive, batteryless, chipless smart surfaces that facilitate IoT communication and sensing.  These surfaces can be fabricated through ordinary inkjet printing, PCB printing, or 3D printing.  They can help sensing the interaction between human users and everyday objects, thus enabling challenging use cases such as experience sampling and mobile VR interaction.  In addition, they can communicate with ordinary radio/radar devices, and boost the quality of existing wireless links. Realizing such capabilities involves non-trivial challenges, especially since the surfaces are fully passive and do not possess the computing/communication components in typical IoT devices.  This talk will introduce a set of solutions that span the areas of electromagnetics, wireless communications, and application-specific signal processing.

Title: Open Set Wireless Transmitter Authorization: Deep Learning Approaches and Practical Considerations

Abstract: As the Internet of Things (IoT) continues to grow, ensuring the security of systems that rely on wireless IoT devices has become critically important. Deep learning-based passive physical layer transmitter authorization systems, referred as RF fingerprinting, have been introduced recently for this purpose. RF fingerprinting approaches use wireless signals directly to verify identity of radio frequency transmitters based on imperfections in their radio hardware. However, most of the existing work using machine learning for RF fingerprinting has mainly focused on classification approaches assuming a closed set of transmitters. In practice, most serious security problems would arise if malicious transmitters outside this closed set are misclassified and authorized. In this talk, we formulate the problem of recognizing authorized transmitters and rejecting new transmitters as open set recognition and anomaly detection. We consider approaches based on one and several binary classifiers, multi-class classifiers, and signal reconstruction, and study how these approaches scale with the number of authorized transmitters. We propose using a known set of unauthorized transmitters to assist the training and study its impact. The authorization robustness against temporal changes in fingerprints is also evaluated as a function of the approach and the dataset structure. For this work, we have created a large Wi-Fi dataset consisting of about 10 million packets sent by 174 off-the-shelf Wi-Fi radios and simultaneously captured by 41 USRPs during 4 captures performed in ORBIT testbed along a month. We have also developed generative deep learning methods to emulate unauthorized signal samples for the augmentation of training datasets. We explored two different data augmentation techniques, one that exploits a limited number of known unauthorized transmitters and the other that does not require any unauthorized transmitters. Our results indicate that data augmentation allows for significant increases in open set classification accuracy, especially when the authorized set is small. Another practical problem in authentication systems based on deep learning is training time when the new transmitters are added. We have developed a fast authentication algorithm based on information retrieval that uses feature vectors as RF fingerprints and locality sensitive hashing(LSH) to create a database that can quickly searched by approximate nearest neighbor algorithm. The proposed algorithm matches the accuracy of deep learning models, while allowing for more than 100x faster retraining.

Title: Adapting PBFT for Use with Blockchain-enabled IoT Systems

Time and Date: October 15, 2021, at 9:00am EDT

Presenter:  Professor Jelena Mišić, Ryerson University, Canada

Venue: https://zoom.us/j/94733541751?pwd=aXYwT1BFNnBQTkFYWGNzVm8vQkQ0QT09

Abstract: 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 ordererís 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.

Title: Brainstorming Generative Adversarial Networks (BGANs): Framework and Application to Wireless Networks

Date and Time: October 22, 2021 at 10AM EDT

Abstract: Due to major communication, privacy, and scalability challenges stemming from the emergence of large-scale Internet of Things services, machine learning is witnessing a major departure from traditional centralized cloud architectures toward a distributed machine learning (ML) paradigm where data is dispersed and processed across multiple edge devices. A prime example of this emerging distributed ML paradigm is Google’s renowned federated learning framework. Despite the tremendous recent interest in distributed ML, remarkably, prior work in the area remains largely focused on the development of distributed ML algorithms for inference and classification tasks. In contrast, in this talk, we introduce the novel framework of brainstorming generative adversarial networks (BGANs) that constitutes one of the first implementations of distributed, multi-agent generative GAN models that does not rely on a centralized parameter server. We show how BGAN allows multiple agents to gain information from one another, in a fully distributed manner, without sharing their real datasets but by “brainstorming” their generated data samples. We then demonstrate the higher accuracy and scalability of BGAN compared to the state of the art through extensive experiments. We then illustrate how BGAN can be used to address key problems in the field of wireless communications by analyzing a millimeter wave channel modeling problem for wireless networks that rely on unmanned aerial vehicles (UAVs). We conclude this talk with an overview on the future outlook of the exciting area of distributed ML and its current and future applications in wireless systems.
