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 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.

Internet heterogeneity is driving a new challenge in application development: adaptive software. Together with the increased Internet capacity and new access technologies, network congestion and the use of older technologies, wireless access, and peer-to-peer networking are increasing the heterogeneity of the Internet. Applications should provide gracefully degraded levels of service when network conditions are poor, and enhanced services when network conditions exceed expectations. Existing adaptive technologies, which are primarily end-to-end or proxy-based and often focus on a single deficient link, can perform poorly in heterogeneous networks. Instead, heterogeneous networks frequently require multiple, coordinated, and distributed remedial actions. Conductor: Distributed Adaptation for Heterogeneous Networks describes a new approach to graceful degradation in the face of network heterogeneity - distributed adaptation - in which adaptive code is deployed at multiple points within a network. The feasibility of this approach is demonstrated by conductor, a middleware framework that enables distributed adaptation of connection-oriented, application-level protocols. By adapting protocols, conductor provides application-transparent adaptation, supporting both existing applications and applications designed with adaptation in mind. Conductor: Distributed Adaptation for Heterogeneous Networks introduces new techniques that enable distributed adaptation, making it automatic, reliable, and secure. In particular, we introduce the notion of semantic segmentation, which maintains exactly-once delivery of the semantic elements of a data stream while allowing the stream to be arbitrarily adapted in transit. We also introduce a secure architecture for automatic adaptor selection, protecting user data from unauthorized adaptation. These techniques are described both in the context of conductor and in the broader context of distributed systems. Finally, this book presents empirical evidence from several case studies indicating that distributed adaptation can allow applications to degrade gracefully in heterogeneous networks, providing a higher quality of service to users than other adaptive techniques. Further, experimental results indicate that the proposed techniques can be employed without excessive cost. Thus, distributed adaptation is both practical and beneficial. Conductor: Distributed Adaptation for Heterogeneous Networks is designed to meet the needs of a professional audience composed of researchers and practitioners in industry and graduate-level students in computer science.

It is certain that, over the next few years, data traffic will dwarf voice traffic on telecommunications networks. Growth in data-traffic volumes far exceeds that for voice, and is driven by increased use of applications such as e-mail attachments, remote printing and fileserver access, and the now omnipresent World Wide Web. The growth of data networking to connect computers with each other and with their peripheral devices began in earnest in the 1970s, took off in the 1980s and exploded in the 1990s. The early 21st century will see ever faster, more cost effective networks providing flexible data access into ever more businesses and homes. Since the 1970s there have been great advances in technology. For the past twenty years the processing power of computers has continued to grow with no hint of slowing - recall the oft-cited Moore's Law claiming that this power doubles every 18 months. Advances in the data networking equipment required to support the data traffic generated have been enormous. The pace of development from early X. 25 and modem technology through to some of the advanced equipment functionality now available is breathtaking - it is sometimes hard to believe that the practical router is barely ten years old This book provides an overview of the advanced data networking field by bringing together chapters on local area networks, wide area networks and their application."

Intelligence in Networks is a concept, the meaning of which is highly related to the time-period when it is used. In the 1960s, 1970s and 1980s, it was mainly related to the teleservice repertoire `an sich'. In the 1990s, it is more related to efficient flexibility in the introduction of new teleservices and teleservice repertoire. This state-of-the-art text sets out to identify and study issues related to solutions for increasing intelligence in networks. As examples, intelligence networks (IN), telecommunication information networking architecture (TINA) and mobile agents and active networks are different solutions for improving the grade of network intelligence. The areas under discussion include research and development within various closely related fields such as: Teleservices, service architecture and service creation; Middleware and specification languages; Mobile agents, active networks, plug-and-play issues; and Quality of service and performance.GBP/LISTGBP Intelligence in Networks contains the proceedings of SMARTNET'99, the fifth in a series of conferences on intelligence in networks sponsored by the International Federation for Information Processing (IFIP), at the Asian Institute of Technology, Pathumthani, Thailand in November 1999.

Third generation networks have been specified and are now being deployed in a few countries. They are expected to reach maturity in the next several years and to provide various services including audio, video, and world wide web browsing. Furthermore, radio terminals are expected to be integrated in a number of devices such as personal computers, personal digital assistants, and even television sets. Such a wide-usage of radio mandates ongoing research to address design of networks with high capacity while providing acceptable quality of service. Included in Multiaccess, Mobility and Teletraffic for Wireless Communications: Volume 6 are new results on the optimization of protocols in third generation systems. The radio channel is dynamically shared among several users using packet access, it must adapt to a varying number of users and accomodate various services. Several chapters deal with radio resource management and packet access both in second and third generation systems. The book also considers the performance of low layer protocols (MAC/RLC) and transport protocols (e.g., TCP) when they are combined to offer data services. IPv6 will probably be an in-use network protocol in the near future. It must efficiently manage mobility and support multimedia flows. Wireless internet is an important area and related topics are included in this book. The improvement of the network performance relies on a sophisticated and optimized physical layer. The book includes studies on joint multiple access detection, MIMO systems, use of turbo-codes and methods to improve the analysis of the channel capacity. The book also covers location management, handoff optimization, multi-hop networks andnetwork management. Mobility and Teletraffic for Wireless Communications: Volume 6 is an important book for researchers, students and professionals working in the area of wireless communications and mobile computing.

Cross-Media Service Delivery is of interest to professionals and academicians working in content authoring and electronic publishing platforms; as well as in media and broadcasting.
The digitization of traditional media formats, such as text, images, video, and sound provides us with the ability to store, process, and transport content in a uniform way. This has led the formerly distinct industries of media, telecommunications, and information technology to converge. Cross-media publishing and service delivery are important new trends emerging in the content industry landscape. Mass-media organizations and content providers transitionally targeted content production towards a single delivery channel. However, recent economic and technological changes in the industry led content providers to extend their brands to cover multiple delivery channels. Following the content industry trend to "create once and publish everywhere" - COPE, a number of architectures, technologies, and tools are currently being developed and deployed to facilitate the automatic conversion of content to multiple formats, and the creation of innovative multi-platform services. This new approach enables the seamless access to information over different network infrastructures and client platforms.
This work uniquely brings together a cross-disciplinary core of contributors to address the technical and business issues of cross-media publishing and service delivery. The contributions are organized into four different areas: the business issues driving the requirements for cross media content delivery, the architectures used for delivering content to multiple platforms, technologies that address specificpractical problems, and, last but not least, concrete applications.
