Cognitive radios (CR) technology is capable of sensing its surrounding environment and adapting its internal states by making corresponding changes in certain operating parameters. CR is envisaged to solve the problems of the limited available spectrum and the inefficiency in the spectrum usage. CR has been considered in mobile ad hoc networks (MANETs), which enable wireless devices to dynamically establish networks without necessarily using a fixed infrastructure. The changing spectrum environment and the importance of protecting the transmission of the licensed users of the spectrum mainly differentiate classical MANETs from CR-MANETs. The cognitive capability and re-configurability of CR-MANETs have opened up several areas of research which have been explored extensively and continue to attract research and development. The book will describe CR-MANETs concepts, intrinsic properties and research challenges of CR-MANETs. Distributed spectrum management functionalities, such as spectrum sensing and sharing, will be presented. The design, optimization and performance evaluation of security issues and upper layers in CR-MANETs, such as transport and application layers, will be investigated.

Broadband Satellite Communication Systems and the Challenges of Mobility is an essential reference for both academic and professional researchers in the field of telecommunications, computer networking and wireless networks.

Recently the request of multimedia services has been rapidly increasing and satellite networks appear to be attractive for a fast service deployment and for extending the typical service area of terrestrial systems. In comparison with traditional wide area networks, a characteristic of satellite communication systems is their ability in broadcasting and multicasting multimedia information flows anywhere over the satellite coverage. The papers presented in this volume highlight key areas such as Satellite Network Architectures, Services and Applications; Mobile Satellite Systems and Services; and Hybrid Satellite and Terrestrial Networks.

Mobility will inevitably be one of the main characteristics of future networks, terminals and applications and, thus, extending and integrating fixed network protocols and services to mobile systems represents one of the main issues of present networking. The secondary focus of this volume is on challenges of mobility, that is, on technologies, protocols and services for the support of seamless and nomadic user access to new classes of applications in person-to-person, device-to-device and device-to-person environments. The book comprises recent results of research and development in the following areas; Seamless mobility; Mobile ad hoc and sensor networks; Analysis, simulation and measurements of mobile and wireless systems; Integration and inter-working of wired and wireless networks; QoS in mobile and wireless networks; Future trends and issues concerning mobility.

I have written this book to ?ll a void between theory and practice, a void that Iperceivedwhileconductingmyownresearchanddevelopmentofcomponents and instruments over the last ?ve years. In the chapters that follow I have pulled materials from the technical and patent literature that are relevant to the understanding and practice of polarization optics in telecommuni- tions, material that is often known by the respective experts in industry and academia but is rarely if ever found in one place. By bringing this material intoonemonograph, andbyapplyingasingleformalismthroughout, Ihopeto create a "base level" upon which future research and development can grow. Polarization optics in telecommunications is an ever-evolving ?eld. Each yearsigni?cantadvancementsaremade, punctuatedbyimportantdiscoveries. The references upon which this book is based are only a snap-shot in time. Areasthatremainunresolvedatthetimeofpublicationmayverywellbecl- i?ed in the years to come. Moreover, the focus of the ?eld changes in time: for instance, there have been few passive nonreciprocal component advancements reported in the last few years, but PMD and PDL advancement continues with only modest abatement.

A book offering advice on how to safeguard a company's telecommunication and computer networks against natural disaster, sabotage and human error. It aims to help identify the vulnerabilities of a system and describes specific risk avoidance measures.

Fiber-optic communication systems have revolutionized our telecommunication infrastructures a" currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information a" only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored.

As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics:

- The transmitter and receiver for phase-modulated coherent lightwave systems

- Method for performance analysis of phase-modulated optical signals

- Direct-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects

- Wavelength-division-multiplexed direct-detection DPSK signals

- Multi-level phase-modulated optical signals, such as the four-phase DQPSK signal.

Graduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field.

Multi-agent systems have numerous civilian, homeland security, and military applications; however, for all these applications, communication bandwidth, sensing range, power constraints, and stealth requirements preclude centralized command and control. The alternative is distributed coordination, which is more promising in terms of scalability, robustness, and flexibility. Distributed Coordination of Multi-agent Networks introduces problems, models, and issues such as collective periodic motion coordination, collective tracking with a dynamic leader, and containment control with multiple leaders, and explores ideas for their solution. Solving these problems extends the existing application domains of multi-agent networks; for example, collective periodic motion coordination is appropriate for applications involving repetitive movements, collective tracking guarantees tracking of a dynamic leader by multiple followers in the presence of reduced interaction and partial measurements, and containment control enables maneuvering of multiple followers by multiple leaders. The authors models for distributed coordination arise from physical constraints and the complex environments in which multi-agent systems operate; they include Lagrangian models more realistic for mechanical-systems modeling than point models and fractional-order systems which better represent the consequences of environmental complexity. Other issues addressed in the text include the time delays inherent in networked systems, optimality concerns associated with the deisgn of energy-efficent algorithms, and the use of sampled-data settings in systems with intermittent neightbor-neighbor contact. Researchers, graduate students, and engineers interested in the field of multi-agent systems will find this monograph useful in introducing them to presently emerging research directions and problems in distributed coordination of multi-agent networks. The Communications and Control Engineering series reports major technological advances which have potential for great impact in the fields of communication and control. It reflects research in industrial and academic institutions around the world so that the readership can exploit new possibilities as they become available.

The Internet of Things (IoT) is the next big challenge for the research community. The IPv6 over low power wireless personal area network (6LoWPAN) protocol stack is considered a key part of the IoT. In 6LoWPAN networks, heavy network traffic causes congestion which significantly degrades network performance and impacts on quality of service aspects. This book presents a concrete, solid and logically ordered work on congestion control for 6LoWPAN networks as a step toward successful implementation of the IoT and supporting the IoT application requirements. The book addresses the congestion control issue in 6LoWPAN networks and presents a comprehensive literature review on congestion control for WSNs and 6LoWPAN networks. An extensive congestion analysis and assessment for 6LoWPAN networks is explored through analytical modelling, simulations and real experiments. A number of congestion control mechanisms and algorithms are proposed to mitigate and solve the congestion problem in 6LoWPAN networks by using and utilizing the non-cooperative game theory, multi-attribute decision making and network utility maximization framework. The proposed algorithms are aware of node priorities and application priorities to support the IoT application requirements and improve network performance in terms of throughput, end-to-end delay, energy consumption, number of lost packets and weighted fairness index.
