Blockchain-Empowered Networks for IoT

Recent advances in blockchain technology have led to a significant interest for managing database in a decentralized way without security concerns that stem from centralized platforms. Hence, blockchain is predicted to be a key enabler for various applications such as an autonomous platform, resource sharing, ubiquitous edge computing, and content-based-storage in IoT and 6G. However, despite of all the benefits of blockchain, there is an inevitable cost to pay, the additional processing latency, which can be crucial for real-time decision making IoT applications.

In this talk, with focusing on this latency, I will explore how we can leverage blockchain for IoT. Specifically, I will provide the overall structure of the blockchain networks, especially for the Hyperledger Fabric, which is one of the most popular private blockchain platforms. I will then discuss whether the blockchain is suitable for latency-sensitive applications by analyzing the data freshness in the blockchain-enabled monitoring networks. I will finally discuss the future challenges of blockchain-enabled networks for IoT.

Chip to Chip Communications across a Galvanically Isolated Barrier

Sending a signal across a galvanically isolated barrier is a common requirement in many aspects of modern electronic machinery. Traditionally such components utilize optical methods such as a LED and a photodetector to send NRZ signals across a galvanic isolation barrier that can withstand hundreds to thousands of volts. These components, generally known as optocouplers, are an essential component isolating the high voltage power devices such as IGBTs from the low voltage controllers which is needed to provide logic and control functions to realize a complete power system.

While Moore’s law dictates that the intelligent controller’s voltages will scale towards lower voltages, the drive towards efficiency and size reduction of magnetics and copper windings requires ever higher operating voltages of the power stages. These two trends are divergent and the requirements of better and more robust communications across the isolation barrier is needed. Besides optical, other methods such as magnetic or capacitive means have been deployed successfully to manage both high voltages and noise isolation and yet provide robust data communications from chip to chip enabling high efficiency and small form factor power solutions suitable for robotics and e-Car applications.

The application of wireless communication in isolation device is still based on relatively simple mechanisms and signalling schemes and opportunities exists to explore and develop better chip to chip wireless communications for future products and applications.

Holographic MIMO Communications

Massive MIMO refers to a wireless network technology where the base stations are equipped with a very large number of antennas to serve a multitude of terminals by spatial multiplexing. Thanks to the intense research performed over the last decade, Massive MIMO is today a mature technology. Its advantages in terms of spectral efficiency, energy efficiency, and power control are well understood and recognized.

The channel capacity was shown to increase theoretically unboundedly in the regime where the number of antennas grows unboundedly. In practice, however, the number of antennas that fits into the common form factor of a base station site is fundamentally limited.

Hence, a natural question is: how can we practically approach the ‘infinite antenna’ limit? One solution is to integrate a massive (possibly infinite) number of antennas into a compact space, that is, a Holographic MIMO array. Realistic performance assessment of Holographic MIMO communications requires the use of a channel model that reflects the main characteristics of a massive number of antennas in a compact space.

This talk considers arbitrary spatially-stationary scattering and provides a representation that captures the essence of electromagnetic propagation and allows to evaluate the capacity of Holographic MIMO systems. The developed framework generalizes the virtual channel representation, which was originally developed for uniform linear arrays.

Towards 6G Wireless Communication Networks: Vision, Enabling Technologies, and New Paradigm Shifts

Fifth generation (5G) wireless communication networks are being deployed worldwide and more capabilities are in the process of being standardized, such as massive connectivity, ultra-reliability, and low latency. However, 5G will not meet all requirements of the future, and sixth generation (6G) wireless networks are expected to provide global coverage, enhanced spectral/energy/cost efficiency, greater intelligence and security, etc. To meet these requirements, 6G networks will rely on new enabling technologies, i.e., air interface and transmission technologies and novel network architectures, such as waveform design, multiple access, channel coding schemes, multi-antenna technologies, network slicing, cell-free architecture, and cloud/fog/edge computing.

One vision on 6G is that it will have four new paradigm shifts. First, to satisfy the requirement of global coverage, 6G will not be limited to terrestrial communication networks, which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle (UAV) communication networks, thus achieving a space-air-ground-sea integrated communication networks. Multiple spectra will be exploited to further increase data rates and connection density, including the sub-6 GHz, millimeter wave (mmWave), terahertz (THz), and optical frequency bands. Third, facing the very large datasets generated by heterogeneous networks, diverse communication scenarios, large numbers of antennas, wide bandwidths, and new service requirements, 6G networks will enable a new range of smart applications with the aid of AI-related technologies. And, fourth, network security will have to be strengthened when developing 6G networks.

This talk will review recent advances and future trends in these four aspects.

Generalized Multiple Tanks and Applications for Silicon Based RF/mm-wave IC

Radio frequency integrated circuits (RFIC) and mm-wave IC plays crucial role in the modern wireless communication systems in laptop, smart phones, tablet etc. Silicon based technologies with their low cost and high integrity prompt the widely adoption of the RF/mm-wave IC by consumer electronics. However, commercial silicon always faces issues of high substrate loss and metal loss especially for RF/mm-wave IC design caused by low resistivity silicon of ~10Ω/sq. We proposed new methodology of multiple-tank topology to cope with this loss issue. It is found that by using this approach, the performance of dedicated RF/mm-wave IC can be dramatically enhanced. It is also verified experimentally by silicon based IC such as VCO, frequency divider, Switch and other circuits with frequency up to 300GHz. Moreover, it is also used and verified in 60GHz Transceiver SOC.

This talk is solicited to present the proposed method and implementation from the fundamental concept and analysis to the new integrated circuits and system verification.

Rethinking Communication Theory for Wireless Networked Systems

Wireless networks are evolving to cater to emerging cyber-physical and mission-critical interactive systems, such as swarm robotics, self-driving cars, and smart Internet of Things. These systems call for reliable real-time communication, autonomous interactions, and automated decision-making. Do we have the right methods and design tools to support those requirements? Are they any critical knowledge gaps for addressing major theoretical roadblocks?

This talk describes some of the shifts in thinking that may be needed to develop a Post-Shannon theory. We will highlight the potential and the challenges of goal-oriented communication, which aims at redefining timing, importance and effectiveness in future networked intelligent systems.

Random Access for Machine-to-Machine Communications: Connection-based or Connection-free?

With the new wave of digital revolution, wireless communication networks are experiencing a radical paradigm shift from the convectional human-to-human communications to machine-to-machine (M2M) communications. To facilitate the massive access of machine-type devices, random access is expected to play a crucial role in the next-generation M2M communications. Thanks to its distributed nature, random access has found wide applications to various wireless networks including 5G cellular networks and WiFi networks.

In general, random access protocols can be divided into two categories: connection-based or connection-free. The connection-based random access procedure of cellular networks has been long criticized for its low access efficiency for supporting M2M communications, which is mainly attributed to the large overhead of connection establishment. Yet connection-free random access schemes usually suffer from high transmission failure rates, especially in massive access scenarios.

The optimal access design for M2M communications requires a fundamental understanding of the performance limits of connection-based and connection-free random access, which will be the focus of this talk. Specifically, I will introduce our recently proposed unified analytical framework for random access, and show how to characterize the maximum effective throughput of connection-based and connection-free random access to develop criteria for beneficial connection establishment. I will conclude the talk by highlighting the practical implications of the analysis to the access design of M2M communications.
