This book is a practical resource for designing Internet of Things (IoT) networks and implementing IoT applications from the localization perspective. With the emergence of IoT, machine to machine communication, Industrial IoT, and other societal applications, many applications require knowledge of the exact location of mobile IoT nodes in real-time. As the IoT nodes have computational and energy limitations, it is a crucial research challenge to optimize the network's performance with the highest localization accuracy. Many researchers are working towards such localization problems. However, there is no single book available for the detailed study on IoT node localization. This book provides one-stop multidisciplinary solutions for IoT node localization, design requirements, challenges, constraints, available techniques, comparison, related applications, and future directions.

However, distributed infrastructure models, which power remote and hybrid-remote work, are distinctly different from traditional business models. They require the right configurations, tools, security, and processes to succeed. IT professionals need to pivot to meet these new needs. This report is intended for cloud-based or partially cloud-based organizations—particularly small and medium-sized enterprises (SMEs) working with lean teams and tight budgets—looking to build or mature their distributed infrastructure. For those that went remote in 2020, it’s time to reconfigure your temporary remote solutions to more mature, long-standing ones; for new businesses looking to pivot to remote work or build from the ground up, take your clean slate as an opportunity to build strategically, holistically, and purposefully.

This book introduces the Internet access for vehicles as well as novel communication and computing paradigms based on the Internet of vehicles. To enable efficient and reliable Internet connection for mobile vehicle users, this book first introduces analytical modelling methods for the practical vehicle-to-roadside (V2R) Internet access procedure, and employ the interworking of V2R and vehicle-to-vehicle (V2V) to improve the network performance for a variety of automotive applications. In addition, the wireless link performance between a vehicle and an Internet access station is investigated, and a Machine Learning based algorithm is proposed to improve the link throughout by selecting an efficient modulation and coding scheme.

Mobile Edge Computing (MEC) provides cloud-like subscription-oriented services at the edge of mobile network. For low latency and high bandwidth services, edge computing assisted IoT (Internet of Things) has become the pillar for the development of smart environments and their applications such as smart home, smart health, smart traffic management, smart agriculture, and smart city. This book covers the fundamental concept of the MEC and its real-time applications. The book content is organized into three parts: Part A covers the architecture and working model of MEC, Part B focuses on the systems, platforms, services and issues of MEC, and Part C emphases on various applications of MEC.

Learn how to defend against the top cybersecurity threats targeting Microsoft 365 including attacks on Identity, Email and Devices. Network Firewalls have been the de facto security perimeter since they were invented in the late 1980s. If a firewall blocked all incoming traffic from the internet, then the level of difficulty for the hacker was significant. So, what changed? As organizations began adopting Cloud Computing in general, or Software as a Service (SaaS) in particular, the security perimeter shifted to the credentials used to authenticate to internet-connected systems. More than 80% of breaches in the present era can be traced to a guessed or stolen password. For Microsoft 365, the username is the email address, and for 90 percent of all M365 users, it is protected by a single factor (a password). This is a HUGE problem because anyone with an internet connection can attempt to guess the password of nearly any account.

Since the first mobile phones were made available in the 1980s, telecommunication providers have been investing in mobile networks to expand coverage, improve services, and attract more users. First-generation networks supported mobile voice calls but were limited in coverage and capacity. To address those limitations, providers developed and deployed second-generation (2G) mobile networks, then third-generation (3G), and fourth-generation (4G) networks. Each generation offered improved speeds, greater capacity, and new features and services. This book provides a background on mobile technologies, and addresses the race to 5G, factors affecting 5G deployment, and national security.
