Durant la ultima decada, la versio actual de la tecnologia central d'Internet s'esta completant gradualment per una versio mes recent, IPv6 o "IP versio 6." S'esta comencant relativament lentament, pero es pot preveure que anira guanyant velocitat a mesura que mes i mes usuaris i proveidors de serveis es trobin obligats a fer el canvi, entre altres pel futur exhauriment de les adreces actuals. Malauradament, tambe hem de constatar que una gran part dels usuaris a penes n'hem sentit parlar. En aquest text es vol presentar una visio damunt de tot realista i divulgativa d'IPv6. S'hi intenta presentar l'estat de la questio, pero sempre des de la vessant practica i directament aplicable. Tracta aspectes com: que es IPv6? Com ens hi podem connectar? Quins canvis ens representa a nivell organitzatiu de les xarxes que fem servir cada dia? Ho notarem molt? Tambe es comenten quins avantatges i quins possibles inconvenients hi podem trobar, tant avui que estarem en una situacio de transicio entre IPv4 i IPv6, com en el futur moment en que es de preveure tan sols subsistira IPv6.

In recent years, a considerable amount of effort has been devoted, both in industry and academia, towards the design, performance analysis and evaluation of modulation schemes to be used in wireless and optical networks, towards the development of the next and future generations of mobile cellular communication systems. Modulation Theory is intended to serve as a complementary textbook for courses dealing with Modulation Theory or Communication Systems, but also as a professional book, for engineers who need to update their knowledge in the communications area. The modulation aspects presented in the book use modern concepts of stochastic processes, such as autocorrelation and power spectrum density, which are novel for undergraduate texts or professional books, and provides a general approach for the theory, with real life results, applied to professional design. This text is suitable for the undergraduate as well as the initial graduate levels of Electrical Engineering courses, and is useful for the professional who wants to review or get acquainted with the a modern exposition of the modulation theory. The book covers signal representations for most known waveforms, Fourier analysis, and presents an introduction to Fourier transform and signal spectrum, including the concepts of convolution, autocorrelation and power spectral density, for deterministic signals. It introduces the concepts of probability, random variables and stochastic processes, including autocorrelation, cross-correlation, power spectral and cross-spectral densities, for random signals, and their applications to the analysis of linear systems. This chapter also includes the response of specific non-linear systems, such as power amplifiers. The book presents amplitude modulation with random signals, including analog and digital signals, and discusses performance evaluation methods, presents quadrature amplitude modulation using random signals. Several modulation schemes are discussed, including SSB, QAM, ISB, C-QUAM, QPSK and MSK. Their autocorrelation and power spectrum densities are computed. A thorough discussion on angle modulation with random modulating signals, along with frequency and phase modulation, and orthogonal frequency division multiplexing is provided. Their power spectrum densities are computed using the Wiener-Khintchin theorem.

Today all kinds of ubiquitous systems, led by wireless sensor networks, can be seen as an unprecedented privacy risk given their ability to collect information on quantities and situations so far unsuspected. There is therefore an urgent need to develop mechanisms to ensure privacy in sensor networks. Location Privacy in Wireless Sensor Networks focuses on location privacy, by which an attacker might determine the source and destination of communications with simple techniques. This poses a serious threat as the attacker might use this information to reach the assets or individuals being monitored or even to destroy or compromise the whole network. This book will aid in the protection against this serious privacy threat.

The TCP/IP protocol suite is changing dynamically to reflect advances in technology and can be considered to represent the "protocol for the new millenium." The ABCs of TCP/IP reflects these advances and includes new coverage on:

· Practical subnetting examples
· Security threats and countermeasures
· IPSec
· ICMP utilization and threats

This comprehensive reference provides professionals with an overview of the TCP/IP suite and details its key components. While many books on the subject focus on the details and minutae of TCP/IP, this book covers applications, methods, concepts, and economics associated with the TCP/IP stack. It illustrates how to leverage investments in TCP/IP and how to economize network operations. The ABCs of TCP/IP examines: the manner by which various protocols and applications operate, addressing issues, security methods, routing, network design constraints, testing methods, troubleshooting, management issues, and emerging applications.

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.

How Control Exists after Decentralization Is the Internet a vast arena of unrestricted communication and freely exchanged information or a regulated, highly structured virtual bureaucracy? In Protocol, Alexander Galloway argues that the founding principle of the Net is control, not freedom, and that the controlling power lies in the technical protocols that make network connections (and disconnections) possible. He does this by treating the computer as a textual medium that is based on a technological language, code. Code, he argues, can be subject to the same kind of cultural and literary analysis as any natural language; computer languages have their own syntax, grammar, communities, and cultures. Instead of relying on established theoretical approaches, Galloway finds a new way to write about digital media, drawing on his backgrounds in computer programming and critical theory. "Discipline-hopping is a necessity when it comes to complicated socio-technical topics like protocol," he writes in the preface. Galloway begins by examining the types of protocols that exist, including TCP/IP, DNS, and HTML. He then looks at examples of resistance and subversion-hackers, viruses, cyberfeminism, Internet art-which he views as emblematic of the larger transformations now taking place within digital culture. Written for a nontechnical audience, Protocol serves as a necessary counterpoint to the wildly utopian visions of the Net that were so widespread in earlier days.
