This book presents Internet transport economics as a new approach to understanding the packet-switching paradigm of Internet infrastructure as a global transport system for data packets. It is a prescient view of the Internet's evolution into a content-centric service platform where the quality of services (QoS) cannot be guaranteed due to the tens of thousands of autonomous systems that enact business decisions on peering, routing, and pricing in a way that determines aspects of the Internet ecosystem like network topology, latency and throughput of traffic flows, and performance of network applications. The trafficking issues created in this environment are a critical concern and barrier for user applications that require real-time responses, such as telesurgery and teleoperation of autonomous vehicles, and the book presents the Internet transport economics model as the solution.                While engineering and business are the prevailing lenses through which the Internet is viewed, the book builds its methodological framework around transport. Further delving into economics, it establishes how the Internet can be understood as providing transport services for data packets, whose demand and supply are driven by the QoS metrics of delay and loss, which can be regarded as congestion costs that result in equilibrium rates of traffic flows sent by content providers (CPs). The book goes on to present a stylized model of content provider-to-access provider (CP-AP) service as well as congestion equilibrium and rate equilibrium solution concepts under the Internet transport economics framework. These are used to analyze the problem domains of service differentiation, market structure, and data pricing. Finally, it discusses various potential future applications. This book will be of interest to graduate students and researchers in areas of computer networking and performance evaluation.

This book provides a comprehensive review and in-depth discussion of the state-of-the-art research literature and propose energy-efficient computation offloading and resources management for mobile edge computing (MEC), covering task offloading, channel allocation, frequency scaling and resource scheduling. Since the task arrival process and channel conditions are stochastic and dynamic, the authors first propose an energy efficient dynamic computing offloading scheme to minimize energy consumption and guarantee end devices' delay performance. To further improve energy efficiency combined with tail energy, the authors present a computation offloading and frequency scaling scheme to jointly deal with the stochastic task allocation and CPU-cycle frequency scaling for minimal energy consumption while guaranteeing the system stability. They also investigate delay-aware and energy-efficient computation offloading in a dynamic MEC system with multiple edge servers, and introduce an end-to-end deep reinforcement learning (DRL) approach to select the best edge server for offloading and allocate the optimal computational resource such that the expected long-term utility is maximized. Finally, the authors study the multi-task computation offloading in multi-access MEC via non-orthogonal multiple access (NOMA) and accounting for the time-varying channel conditions. An online algorithm based on DRL is proposed to efficiently learn the near-optimal offloading solutions.Researchers working in  mobile edge computing, task offloading and resource management, as well as advanced level students in electrical and computer engineering, telecommunications, computer science or other related disciplines will find this book useful as a reference. Professionals working within these related fields will also benefit from this book.

AI to Prevent Remote Human-to-Human VR & Trafficking Program is a proposed program that would use artificial intelligence (AI) to prevent human trafficking in virtual reality (VR). The program would use a variety of AI techniques, including machine learning and deep learning, to detect suspicious activity in VR, identify victims and perpetrators of human trafficking, and educate and empower users about human trafficking and how to stay safe in VR.The program is still in the early stages of development, but it has the potential to be a powerful tool for preventing human trafficking in VR. VR is a new and emerging technology, and human traffickers have already begun to use it to exploit victims. AI can help to combat this by providing law enforcement and other organizations with the tools they need to identify and rescue victims of human trafficking in VR.The program is also designed to educate and empower users about human trafficking and how to stay safe in VR. This is important because many users are not aware of the risks associated with VR, and they may be more likely to be trafficked if they do not know how to protect themselves.The AI to Prevent Remote Human-to-Human VR & Trafficking Program is a promising new initiative that has the potential to make a real difference in the fight against human trafficking.

Omni-resonant Fabry-Pérot (FP) cavities are a promising new approach to broadband solar energy harvesting. They can overcome the limitations of traditional resonant absorption schemes, which are typically narrowband and require precise matching between the cavity resonance and the wavelength of the incident light.In an omni-resonant FP cavity, the resonant bandwidth is broadened by carefully sculpting the spatio-temporal structure of the incident light. This can be done by using a light preconditioning system that introduces angular dispersion into the incident beam. When the angular dispersion of the incident light is equal in magnitude but opposite in sign to the angular dispersion of the cavity, all wavelengths within a selected band can resonate simultaneously.This results in continuous-wavelength coherent perfect absorption (CPA), which can significantly boost the external quantum efficiency (EQE) of solar cells. In a recent study, researchers demonstrated that a combination of CPA and omni-resonance can lead to a doubling of the photocurrent harvested in the near-infrared spectral range of 660-740 nm in a hydrogenated amorphous silicon (a-Si:H) PIN-diode solar cell.Omni-resonant FP cavities have several advantages over traditional resonant absorption schemes. First, they are broadband, meaning that they can absorb light over a wide range of wavelengths. Second, they are tolerant of misalignment, meaning that they do not require precise matching between the cavity resonance and the wavelength of the incident light. Third, they are scalable, meaning that they can be fabricated using standard thin-film deposition techniques.These advantages make omni-resonant FP cavities a promising candidate for use in next-generation solar cells. They could also be used in other applications where broadband resonant absorption is desired, such as optical sensors and optical filters.

This book examines the critical differences between current and next-generation Si technologies (CMOS, BiCMOS and SiC) and technology platforms (e.g. system-on-chip) in mm-wave wireless applications. We provide a basic overview of the two technologies from a technical standpoint, followed by a review of the state-of-the-art of several key building blocks in wireless systems. The influences of system requirements on the choice of semiconductor technology are vital to understanding the merits of CMOS and BiCMOS devices - e.g., output power, battery life, adjacent channel interference, cost restrictions, and so forth. These requirements, in turn, affect component-level design and performance metrics of oscillators, mixers, power and low-noise amplifiers, as well as phase-locked loops and data converters. Finally, the book offers a peek into the next generation of wireless technologies such as THz -band systems and future 6G applications.

Perfectly-secure cryptography is a branch of information-theoretic cryptography. A perfectly-secure cryptosystem guarantees that the malicious third party cannot guess anything regarding the plain text or the key, even in the case of full access to the cipher text. Despite this advantage, there are only a few real-world implementations of perfect secrecy due to some well-known limitations. Any simple, straightforward modeling can pave the way for further advancements in the implementation, especially in environments with time and resource constraints such as IoT. This book takes one step towards this goal via presenting a hybrid combinatorial-Boolean model for perfectly-secure cryptography in IoT. In this book, we first present an introduction to information-theoretic cryptography as well as perfect secrecy and its real-world implementations. Then we take a systematic approach to highlight information-theoretic cryptography as a convergence point for existing trends in research on cryptography in IoT. Then we investigate combinatorial and Boolean cryptography and show how they are seen almost everywhere in the ecosystem and the life cycle of information-theoretic IoT cryptography. We finally model perfect secrecy in IoT using Boolean functions, and map the Boolean functions to simple, well-studied combinatorial designs like Latin squares.This book is organized in two parts. The first part studie s information-theoretic cryptography and the promise it holds for cryptography in IoT. The second part separately discusses combinatorial and Boolean cryptography, and then presents the hybrid combinatorial-Boolean model for perfect secrecy in IoT.
