Wireless sensor network (WSN) is an ad-hoc network technology comprising even thousands of autonomic and self-organizing nodes that combine environmental sensing, data processing, and wireless networking. The applications for sensor networks range from home and industrial environments to military uses. Unlike the traditional computer networks, a WSN is application-oriented and deployed for a specific task. WSNs are data centric, which means that messages are not send to individual nodes but to geographical locations or regions based on the data content. A WSN node is typically battery powered and characterized by extremely small size and low cost. As a result, the processing power, memory, and energy resources of an individual sensor node are limited. However, the feasibility of a WSN lies on the collaboration between the nodes. A reference WSN node comprises a Micro-Controller Unit (MCU) having few Million Instructions Per Second (MIPS) processing speed, tens of kilobytes program memory, few kilobytes data memory. In addition, the node contains a short-range radio, and a set of sensors. Supply power is typically obtained with small batteries. Assuming a target lifetime of one year using AA-size batteries, the available power budget is around 1 mW. This book covers the low-power WSNs services ranging from hardware platforms and communication protocols to network deployment, and sensor data collection and actuation. The implications of resource constraints and expected performance in terms of throughput, reliability and latency are explained. As a case study, this book presents experiments with low-energy TUTWSN technology to illustrate the possibilities and limitations of WSN applications.

The second edition of WiMax Operator's Manual includes most of the material from the first edition, plus new discussions of ¢ The ultra-high-speed mobile telephone standard, HSDPA ¢ Ultrawideband (UWB) ¢ Changes to DSL technologies ¢ Mobile voice ¢ Mobile entertainment ¢ New backup systems The new edition also reflects the changes that have occurred in the industry over the last year and half, including the emergence of prestandards wireless broadband equipment with fully developed mobile capabilities, significant alterations in the competitive landscape, and the opening of valuable new spectrum for broadband wireless operators. Public broadband wireless data networks represent a truly disruptive technology, one that promises to break the monopolistic and oligopolistic status quo that still represents the norm in high-speed access today. Products that would enable such networks have existed for a number of years and in fact have been deployed in thousands of commercial systems throughout the world, but the lack of standards, the limited production volumes, and the consequent high prices have prevented the full potential of wireless broadband from being realized. Now, with the coming of a widely accepted industry standard, IEEE 802.16, and the introduction of microchips based on that standard by leading semiconductor companies, wi- less broadband public networks are becoming mainstream.

As the number of smart-phone applications and users continues to grow, the future Internet must integrate both optical wired networks and mobile wireless networks in order to meet the demands for pervasive computing and network capacity. This important text/reference reviews the challenges of all-optical and wireless networks for the future Internet. With a focus on cross-layer design and optimization, the book proposes a number of modifications to existing layered reference models, in addition to discussing revisions to current end-to-end arguments. The text also examines how these approaches can enhance the energy efficiency of the network. Topics and features: Presents a thorough introduction to major networking modes and their effect on Internet development Proposes a new structure favorable for all-optical packet switching Discusses a new quality of service (QoS) provisioning approach, which overcomes the scalability problem of IntServ and the coarse QoS granularity of DiffServ Describes the end-to-end arguments in Internet design, before investigating a solution to congestion control problems in multi-hop wireless and all-optical networks Examines how to exploit multiple-input-multiple-output technology to improve network performance in centralized wireless networks Surveys green networking strategies from a quantitative perspective Suggests a strategic vision for possible developments of network technology for the future Internet Presenting state-of-the-art research on new networking approaches, this text is a must-read for all researchers and practitioners interested in developing technologies for next-generation applications and the future Internet.
