In recent years, wireless networks communication has become the fundamental basis of our work, leisure, and communication life from the early GSM mobile phones to the Internet of Things (IoT) and Internet of Everything (IoE) communications. All wireless communications technologies such as Bluetooth, NFC, wireless sensors, wireless LANs, ZigBee, GSM, and others have their own challenges and security threats. This book addresses some of these challenges focusing on the implication, impact, and mitigations of the stated issues. The book provides a comprehensive coverage of not only the technical and ethical issues presented by the use of wireless networks but also the adversarial application of wireless networks and its associated implications. The authors recommend a number of novel approaches to assist in better detecting, thwarting, and addressing wireless challenges and threats. The book also looks ahead and forecasts what attacks can be carried out in the future through the malicious use of the wireless networks if sufficient defenses are not implemented. The research contained in the book fits well into the larger body of work on various aspects of wireless networks and cyber-security.

Blockchain is a digital ledger of transactions duplicated and distributed across an entire network of computer systems on the blockchain which makes it more difficult to hack or tamper with. The popularity of blockchain has been increasing with the growth of social media and the Internet of Things (IoT). Social media are interactive digitally mediated technologies that facilitate the creation or sharing and exchange of information, ideas, opinions and interests via virtual communities and social network platforms. However, unmonitored social accounts can be the target of hackers who post fraudulent messages or virus-infected links that spread to contacts and followers, and "employee weakness" is responsible for 20% of cyberattacks in companies. So, it has become essential to secure both personal and professional social media networks, accounts and data. Blockchain Technology for Secure Social Media Computing covers recent advances, trends and future opportunities in the security framework of social media-computing. The contributors focus on how to protect social media platforms, and present methods for making social media computing more reliable and effective to achieve trusted IoT-based social computing with blockchain technology.

Data Communications and Networking, 6th Edition, teaches the principles of networking using TCP/IP protocol suite. It employs a bottom-up approach where each layer in the TCP/IP protocol suite is built on the services provided by the layer below. This edition has undergone a major restructuring to reduce the number of chapters and focus on the organization of TCP/IP protocol suite. It concludes with three chapters that explore multimedia, network management, and cryptography/network security. Technologies related to data communications and networking are among the fastest growing in our culture today, and there is no better guide to this rapidly expanding field than Data Communications and Networking.

В монографии рассмотрены основные методы увеличения скорости передачи сигналов в пассивных оптических сетях доступа (PON) с помощью частотного разделения каналов в оптическом (DWDM) и радиочастотном диапазонах (SCM). Предложены новые технические решения для увеличения пропускной способности существующих PON-сетей путем незначительных изменений в оптической инфраструктуре сети доступа, замены активного оборудования на более широкополосное с частотным разделением каналов.

Network engineers are finding it harder than ever to rely solely on manual processes to get their jobs done. New protocols, technologies, delivery models, and the need for businesses to become more agile and flexible have made network automation essential. The updated second edition of this practical guide shows network engineers how to use a range of technologies and tools, including Linux, Python, APIs, and Git, to automate systems through code. This edition also includes brand new topics such as network development environments, cloud, programming with Go, and a reference network automation architecture. Network Programmability and Automation will help you automate tasks involved in configuring, managing, and operating network equipment, topologies, services, and connectivity. Through the course of the book, you'll learn the basic skills and tools you need to make this critical transition. Should Network Engineers Learn to Code? Unfortunately, you aren’t getting a definitive yes or no from us. Clearly, we have a full chapter on Python and another on Go, and plenty of examples throughout the book on how to use Python or Go to communicate to network devices via network APIs and extend DevOps tools like Ansible and Terraform, so we definitely think learning the basics of any programming language is valuable.
