Achieving Federated and Self-Manageable Cloud Infrastructures: Theory and Practice overviews current developments in cloud computing concepts, architectures, infrastructures and methods, focusing on the needs of small to medium enterprises. The topic of cloud computing is addressed on two levels: the fundamentals of cloud computing and its impact on the IT world; and an analysis of the main issues regarding the cloud federation, autonomic resource management, and efficient market mechanisms, while supplying an overview of the existing solutions able to solve them. This publication is aimed at both enterprise business managers and research and academic audiences alike.

Software design is becoming increasingly complex and difficult as we move to applications that support people interacting with information and with each other over networks. Computer supported cooperative work applications are a typical example of this. The problems to be solved are no longer just technical, they are also social: how do we build systems that meet the real needs of the people who are asked to use them and that fit into their contexts of use. We can characterise these as wicked problems, where our traditional software engineering techniques for understanding requirements and driving these through into design are no longer adequate.

This book presents the Locales Framework - and its five aspects of locale foundations, civic structures, individual views, interaction trajectory and mutuality - as a way of dealing with the intertwined problem-solution space of wicked problems. A locale is based on a metaphor of place as the lived relationship between people and the spaces and resources they use in their interactions. The Locales Framework provides a coherent mediating framework for ethnographers, designers, and software engineers to facilitate both understanding requirements of complex social situations and designing solutions to support these situations in all their complexity.

The book is well versed with the hottest research topics such as Lifetime of Coverage, Weighted Sensor Cover, k-Coverage, Heterogeneous Sensors, Barrier, Sweep and Partial Coverage, Mobile Sensors, Camera Sensors and Energy-Harvesting Sensors, and more. Topics are introduced in a natural order from simple covers to connected covers, to the lifetime problem. Later, the book begins revisiting earlier problems ranging from the introduction of weights to coverage by k sensors and partial coverage, and from sensor heterogeneity to novel problems such as the barrier coverage problem. The book ends with coverage of mobile sensors, camera sensors, energy-harvesting sensors, underwater sensors, and crowdsensing.

This book explores how novel digital services, including e-services, digital platforms and mobile apps, are increasingly being innovated through open processes. It investigates how and why organizations invite external developers to participate in their innovation, often catalyzed by contests and the provision of open data, with the aim of designing digital services that go beyond the capability of the organizations themselves. Taking a contest driven approach to innovation, the book provides an accessible yet comprehensive introduction to the area of open digital innovation. It offers an analysis of key scientific principles underlying open innovation and based on these provides practical tools for improving the digital innovation process. Furthermore, the book introduces instruments for managing innovation contests, in particular for overcoming innovation barriers and for harnessing the power of motivating factors. It serves as a text for graduate and undergraduate courses in digital innovation and entrepreneurship, but is also a valuable resource for managers as well as policy makers in the field of open digital innovation.

This book gives an overview of constraint satisfaction problems (CSPs), adapts related search algorithms and consistency algorithms for applications to multi-agent systems, and consolidates recent research devoted to cooperation in such systems. The techniques introduced are applied to various problems in multi-agent systems. Among the new approaches is a hybrid-type algorithm for weak-commitment search combining backtracking and iterative improvement; also, an extension of the basic CSP formalization called partial CSP is introduced in order to handle over-constrained CSPs.The book is written for advanced students and professionals interested in multi-agent systems or, more generally, in distributed artificial intelligence and constraint satisfaction. Researchers active in the area will appreciate this book as a valuable source of reference.

Safety is a paradoxical system property. It remains immaterial, intangible and invisible until a failure, an accident or a catastrophy occurs and, too late, reveals its absence. And yet, a system cannot be relied upon unless its safety can be explained, demonstrated and certified. The practical and difficult questions which motivate this study concern the evidence and the arguments needed to justify the safety of a computer based system, or more generally its dependability. Dependability is a broad concept integrating properties such as safety, reliability, availability, maintainability and other related characteristics of the behaviour of a system in operation. How can we give the users the assurance that the system enjoys the required dependability? How should evidence be presented to certification bodies or regulatory authorities? What best practices should be applied? How should we decide whether there is enough evidence to justify the release of the system? To help answer these daunting questions, a method and a framework are proposed for the justification of the dependability of a computer-based system. The approach specifically aims at dealing with the difficulties raised by the validation of software. Hence, it should be of wide applicability despite being mainly based on the experience of assessing Nuclear Power Plant instrumentation and control systems important to safety. To be viable, a method must rest on a sound theoretical background.

Who makes WiFi?
Why do different makers matter?
What do barbeques and backyards have to do with the internet?
This book explores how WiFi is made from the ground up, or in this case from the backyard out. Forged around barbeques, made of found, adapted and off-the-shelf materials and installed in ordinary domestic spaces, this book documents the collective work of individuals committed to making 'Ournet not the internet'.
Drawing on rich ethnographic material, Jungnickel's research on community WiFi networking provides an overdue account of the innovative digital cultures and practices of ordinary people making extra-ordinary things. What make-do methods, mods and tales of resourceful ingenuity permit is another way of seeing how technologies come into being. It brings to life an Australian version of WiFi, enriching global studies of wireless technology by signalling the potential of comparative studies.
Critically, the book presents the first sustained study of homebrew high-tech backyard technologists who imbue a DIY ethos but do not do it alone - they Do-It-Together (DIT). This timely critique of collective DIT innovation in an increasingly networked society will be of interest to scholars and practitioners of maker culture.

The telecommunications industry is experiencing a worldwide explosion of growth as few other industries ever have. However, as recently as a decade ago, the bulk of telecommunications services were delivered by the traditional telephone network, for which design and analysis principles had been under steady development for over three-quarters of a century. This environment was characterized by moderate and steady growth, with an accompanying slower development of new network equipment and standardization processes. In such a near-static environment, attention was given to optimization techniques to squeeze out better profits from existing and limited future investments. To this end, forecasts of network services were developed on a regular planning cycle and networks were optimized accordingly, layer by layer, for cost-effective placement of capacity and efficient utilization. In particular, optimization was based on a fairly stable set of assumptions about the network architecture, equipment models, and forecast uncertainty. This special edition is devoted to heuristic approaches for telecommunications network management, planning, and expansion. We hope that this collection brings to the attention of researchers and practitioners an array of techniques and case studies that meet the stringent time to market' requirements of this industry and which deserve exposure to a wider audience. Telecommunications will face a tremendous challenge in the coming years to be able to design, build, and manage networks in such a rapidly evolving industry. Development and application of heuristic methods will be fundamental in our ability to meet this challenge.

This book explores potentially disruptive and transformative healthcare-specific use cases made possible by the latest developments in Internet of Things (IoT) technology and Cyber-Physical Systems (CPS). Healthcare data can be subjected to a range of different investigations in order to extract highly useful and usable intelligence for the automation of traditionally manual tasks. In addition, next-generation healthcare applications can be enhanced by integrating the latest knowledge discovery and dissemination tools. These sophisticated, smart healthcare applications are possible thanks to a growing ecosystem of healthcare sensors and actuators, new ad hoc and application-specific sensor and actuator networks, and advances in data capture, processing, storage, and mining. Such applications also take advantage of state-of-the-art machine and deep learning algorithms, major strides in artificial and ambient intelligence, and rapid improvements in the stability and maturity of mobile, social, and edge computing models.

The primary objective of this book is to teach the architectures, design principles, and troubleshooting techniques of a LAN. This will be imparted through the presentation of a broad scope of data and computer communication standards, real-world inter-networking techniques, architectures, hardware, software, protocols, technologies and services as they relate to the design, implementation and troubleshooting of a LAN. The logical and physical design of hardware and software is not the only process involved in the design and implementation of a LAN. The latter also encompasses many other aspects including making the business case, compiling the requirements, choosing the technology, planning for capacity, selecting the vendor, and weighing all the issues before the actual design begins.

As the IoT market is booming, several issues are delaying the full realization of the technology. IoT devices, in cybersecurity terms, greatly increase security risk. This means that any scientific work that offers cybersecurity strategies will excite security experts who will be glad to expand their knowledge base on IoT cybersecurity. As a result of the booming of the IoT market, business competitors are jockeying for a piece of the market. This means that solutions from researchers that address compatibility issues will be greatly welcomed by IoT technology developers. Connectivity providers are likely to embrace solutions to challenges of bandwidth since a growing IoT market must be followed up by bandwidth-intensive IoT applications which tend to jostle for space on the current client-server model. Overpromising followed by underdelivering, has been the current approach by many innovators and the mismatch results in losses in production, orphaned technologies accompanied by frequent system failures. Solutions that address IoT performance issues are likely to excite many start-ups. Solutions to challenges of fragmentation presented by thousands of devices from different manufacturers operating on proprietary ecosystems are likely to be warmly embraced by many IoT brands developers. As such, a publication that specifically addresses the challenges faced in the rolling out of IoT technologies is sorely needed.

The Palm theory and the Loynes theory of stationary systems are the two pillars of the modern approach to queuing. This book, presenting the mathematical foundations of the theory of stationaryqueuing systems, contains a thorough treatment of both of these.

This approach helps to clarify the picture, in that it separates the task of obtaining the key system formulas from that of proving convergence to a stationary state and computing its law.

The theory is constantly illustrated by classical results and models: Pollaczek-Khintchin and Tacacs formulas, Jackson and Gordon-Newell networks, multiserver queues, blocking queues, loss systems etc., but it also contains recent and significant examples, where the tools developed turn out to be indispensable.

Several other mathematical tools which are useful within this approach are also presented, such as the martingale calculus for point processes, or stochastic ordering for stationary recurrences.

This thoroughly revised second edition contains substantial additions - in particular, exercises and their solutions - rendering this now classic reference suitable for use as a textbook.

This book comprises the proceedings of ICITCS 2021. It aims to provide a snapshot of the latest issues encountered in IT convergence and security. The book explores how IT convergence and security are core to most current research, industrial, and commercial activities. Topics covered in this book include machine learning & deep learning, communication and signal processing, computer vision and applications, future network technology, artificial intelligence and robotics, software engineering and knowledge engineering, intelligent vehicular networking and applications, health care and wellness, web technology and applications, Internet of things, and security & privacy. Through this book, readers gain an understanding of the current state-of-the-art information strategies and technologies in IT convergence and security. The book is of use to researchers in academia, industry, and other research institutes focusing on IT convergence and security.
