In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.

Until the 1990s, almost all spectrum licenses were given away practically for free-even the first mobile licenses which laid the foundation for multi-billion dollar companies that dominate stock markets around the world. In the past fifteen years, there has been a concerted attempt to liberalise the sector and make it more open to market forces. This book examines this attempt. Exploring the new frontier for spectrum policy, Understanding Spectrum Liberalisation identifies the successes and failures of the main policy initiatives of the past decade. It explains, in layman's terms, the technical and policy background needed to understand these debates. For those already working in the field, the book provides a lively analysis of recent policy initiatives along with an authoritative interpretation of the latest developments in spectrum policy. It examines individual liberalisation initiatives in detail and explains the logic behind moves towards spectrum sharing, which is seen as the next policy phase. This book will help non-specialists climb the formidable learning curve quickly. It is ideal for those who have just become involved in the spectrum field, whether in industry, government, or as a regulator, as well as those with expertise in one area of spectrum management who want to learn more about the other areas. History is about the concerns of the present, so the saying goes, and the authors hope that their interpretation of the very recent past will stimulate debate about future policy and help you make substantive contributions to ongoing policy debates.

Thanks to the advancement of faster processors within communication devices, there has been a rapid change in how information is modulated, multiplexed, managed, and moved.

The third edition of Introduction to Communications Technologies: A Guide for Non-Engineers helps students in telecommunications business programs become familiar with and stay abreast of the ever-changing technology surrounding their industry. Used in the core curriculum at Ball State University's graduate professional program in Information and Communication Sciences, this textbook is designed for graduate and undergraduate students who do not necessarily have a high level of technical expertise, but need to have some understanding of the technical functions of information and communication technologies to prepare them for working in a corporate environment. See What's New in the Third Edition: Significant updates to the following chapters: Modulation Schemes; Signaling Formats, Multiplexing, and Digital Transmission; Packet Switching and Local Area Networks; Mobile Wireless Technologies; Network Security and Management Added coverage of OFDMA, Metro Ethernet, 5G pre-standard configuration, 'apps' on mobile devices, and VoIP core switching New chapters on Big Data and the Cloud Avoiding complicated equations and the need for calculus gymnastics, this textbook provides non-engineering students with a firm background and a broad understanding of the knowledge necessary to work within the fast-paced and ever-changing communications industry.

While there are many scholarly books and papers that cover the technical issues behind the public switched telephone network (PSTN) migration, few books describe exactly how to manage the migration process economically. Filling this need, Managing the PSTN Transformation: A Blueprint for a Successful Migration to IP-Based Networks reflects the latest understanding of the challenges behind migrating customers from the old PSTN network to an IP infrastructure. The IP transformation blueprint described in this book is not a theoretical cookbook that describes how this could work. Instead, the book presents a blueprint that is the product of countless hours of work by hundreds of individuals at Deutsche Telekom (DT) over almost two years. The book presents insights gained as the DT team migrated the entire public switched telephone network in Macedonia to an Internet protocol-based platform. It illustrates the various types of challenges the team faced in integrating complex systems, including flight control at their airports, alarms for fire and police response, and large enterprise customers. Detailing new conceptual approaches and the best practices developed for ensuring knowledge transfer within the DT group, the book presents the information in a step-by-step manner to enable you to easily adapt the blueprint for particular service provider requirements. Since successful migration relies on key aspects beyond the technological side, this work provides you with a product portfolio roadmap, migration plan, IT roadmap, business case framework, and a go-to-market plan. Although the book discusses the experiences of the Deutsche Telekom team as they worked to migrate the telephone network in Macedonia to an Internet protocol-based platform, the IP transformation blueprint and lessons learned presented can easily be scaled up and applied to any market around the world.

In this book, Steffen Lange and Tilman Santarius investigate how digitalization influences environmental and social sustainability. The information revolution is currently changing the daily lives of billions of people worldwide. At the same time, the current economic model and consumerist lifestyle needs to be radically transformed if society is to overcome the challenges humanity is facing on a finite planet. Can the much-discussed disruption potential of digitalization be harnessed for this purpose? Smart Green World? provides guiding principles for a sustainable digital society and develops numerous hands-on proposals for how digitalization can be shaped to become a driving force for social transformation. For instance, the authors explain why more digitalization is needed to realize the transition towards 100% renewable energy and show how this can be achieved without sacrificing privacy. They analyze how the information revolution can transform consumption patterns, mobility habits and industry structures - instead of fostering the consumption of unneeded stuff due to personalized commercials and the acceleration of life. The authors reveal how Artificial Intelligence and the Industrial Internet of Things pose novel environmental challenges and contribute to a polarization of income; but they also demonstrate how the internet can be restored to its status as a commons, with users taking priority and society at large reaping the benefits of technological change in a most democratic way. Providing a comprehensive and practical assessment of both social and environmental opportunities and challenges of digitalization, Smart Green World? Making Digitalization Work for Sustainability will be of great interest to all those studying the complex interrelationship of the twenty-first-century megatrends of digitalization and decarbonization.

‘Mr Watson, come here, I want to see you.’

It’s been almost 150 years since Alexander Graham Bell said these immortal words on the first ever phone call, to his assistant in the next room. Between 10 March 1876 and now, the world has changed beyond recognition. And telecommunications, which has played a fundamental role in this change, has itself evolved into an industry that was the sole preserve of science fiction.

When the world’s first modern mobile telephone network was launched in 1979, there were just over 300 million telephones. Today, there are more than eight billion, most of which are mobile. Most people in most countries can now contact each other in a matter of seconds. Soon we’ll all be connected, to each other, and to complex computer networks that provide us with instant information, but also observe and record our actions. No other phenomenon touches so many of us, so directly, each and every day of our lives.

This book describes how this transformation came about. It considers the technologies that underpin telecommunications – microcircuits, fibre-optics and satellites – and touches on financial aspects of the industry: privatisations, mergers and takeovers that have helped shape the $2-trillion telecom market. But for the most part, it’s a story about us and our need to communicate.
