'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. A concise edition of John Tysoe and Alan Knott-Craig's magnum opus, A History of Telecommunications, this book gives you the information you need to know about what keeps us connected and how we got here.

It elaborates the network utility maximization (NUM) theory with applications in resource allocation of wireless networks, with a central aim of design and the QoS guarantee. It presents and discusses state-of-the-art developments in resource allocation and performance optimization in wireless communication networks. It provides an overview of the general background including the basic wireless communication networks and the relevant protocols, architectures, methods and algorithms.
Media, Materiality and Memory
Media, Materiality and Memory: Grounding the Groove examines the entwinement of material music objects, technology and memory in relation to a range of independent record labels, including Sarah Records, Ghost Box and Finders Keepers. Moving from Edison's phonograph to digital music files, from record collections to online archives, Roy argues that materiality plays a crucial role in constructing and understanding the territory of recorded sound. How do musical objects 'write' cultural narratives? How can we unearth and reactivate past histories by looking at yesterday's media formats? What is the nature, and fate, of the physical archive in an increasingly dematerialized world? In what ways do physical and digital musical objects coexist and intersect? With its innovative theoretical approach, the book explores the implications of materialization in the fashioning of a musical world and its cultural transmission. A substantial contribution to the field of music and material culture studies, Media, Materiality and Memory also provides a nuanced and timely reflection on nostalgia and forgetting in the digital age.
New Directions in Wireless Communications Systems
Beyond 2020, wireless communication systems will have to support more than 1,000 times the traffic volume of today's systems. This extremely high traffic load is a major issue faced by 5G designers and researchers. This challenge will be met by a combination of parallel techniques that will use more spectrum more flexibly, realize higher spectral efficiency, and densify cells. Novel techniques and paradigms must be developed to meet these goals. The book addresses diverse key-point issues of next-generation wireless communications systems and identifies promising solutions. The book's core is concentrated to techniques and methods belonging to what is generally called radio access network.
Handbook of SDP for Multimedia Session Negotiations
This book on SDP is the first of this kind that attempts to put all SDP related RFCs together with their mandatory and optional texts in a chronological systematic way as if people can use a single "super-SDP RFC" with almost one-to-one integrity from beginning to end to see the big picture of SDP in addition to base SDP functionalities.
Cognitive Sensors and Iot
This book presents the Cognitive Information Centric Sensor Network (CICSN) framework for the IoT. This framework is built on top of cognitive nodes, capable of knowledge representation, learning, and reasoning, along with an information-centric approach for data delivery. It also discusses the most appropriate deployment strategy for these cognitive nodes under realistic assumptions that cares about the Quality of Information (QoI). In addition, it uses a QoI aware data delivery strategy, with Analytic Hierarchy Process (AHP) as the reasoning technique to identify data delivery paths that dynamically adapt to changing network conditions and user requirements.
Wireless Sensor Networks
Wireless Sensor Networks overcome the difficulties of other monitoring systems. However, they require further efficiencies for Outdoor Environment Monitoring (OEM) applications due to their harsh operational conditions, huge targeted areas, limited energy budget, and required 3D setups. A fundamental issue in defeating these practical challenges is deployment planning. The deployment plan is a key factor of many intrinsic properties of OEM networks, summarized in connectivity, lifetime, fault-tolerance, and cost-effectiveness. This book investigates the problem of WSNs deployments that address these properties in order to overcome the unique challenges and circumstances in OEM applications.
