A Petri net is a mathematical representation of a network. This book first introduces the basic models including time and stochastic extensions, in particular place-transition and high level Petri nets. Their modeling and design capabilities are illustrated by a set of representations of interest in operating and communication systems. The...

It is commonly accepted today that optical fiber communications have revolutionized telecommunications. Indeed, dramatic changes have been induced in the way we interact with our relatives, friends, and colleagues: we retrieve information, we entertain and educate ourselves, we buy and sell, we organize our activities, and so on, in a long...

WiMAX is the first standard technology to deliver true broadband mobility at speeds that enable powerful multimedia applications such as Voice over Internet Protocol (VoIP), online gaming, mobile TV, and personalized infotainment. WiMAX Security and Quality of Service, focuses on the interdisciplinary subject of advanced Security and...

After decades of liberalization of the telecommunications industry around the world and technological convergence that allows for increasing competition, sector-specific regulation of telecommunications has been on the decline. As a result, the telecommunications industry stands in the middle of a debate that calls for either a total...

In this book, the authors provide an insight into the field of RFID systems with an emphasis on networking aspects and research challenges related to passive Ultra High Frequency (UHF) RFID systems. The book reviews...

The book addresses the problem known in the literature as Open and Distance Learning (ODL). ODL describes new concepts of the process of learning-teaching organization. ODL is becoming very popular at universities that offer education via online and/or distance learning, both in synchronous or asynchronous modes. More precisely, the...

Recently, the rapid and fundamental advances in computing technologies have been driving the role and scope of software systems to a new level. A number of new types of software systems are emerging, among which service based systems, cloud computing, pervasive computing, and Internet of Things are eminent examples. For these systems,...

The continuing explosive growth in mobile communication is demanding more spectrally efficient radio access technologies than the prevalent second generation (2G) systems such as GSM to handle just the voice traffic. We are already witnessing high levels of mobile penetration exceeding 70% in some countries. It is anticipated that by...

The history of software development paradigms suggests that a new paradigm often has its genesis in programming languages and then moves up to design and analysis (e.g., structured programming preceded structured design and analysis, and objectoriented programming predated object-oriented design and modeling). This same pattern can...

This book originates from the desire to perpetuate expertise in the field of performance evaluation, particularly for telecommunication systems and networks. It is obviously impossible to translate into a single work all the facets of an activity which encompasses many systems and a great variety of domains such as standardization,...
