Improving the Performance of Wireless LANs

This book quantifies the key factors of WLAN performance and describes methods for improvement. It provides theoretical background and empirical results for the optimum planning and deployment of indoor WLAN systems, explaining the fundamentals while supplying guidelines for design, modeling, and performance evaluation. It discusses environmental effects on WLAN systems, protocol redesign for routing and MAC, and traffic distribution; examines emerging and future network technologies; and includes radio propagation and site measurements, simulations for various network design scenarios, numerous illustrations, practical examples, and learning aids

eHealth Conversations : using information management, dialogue, and knowledge exchange to move toward universal

The publication of eHealth Conversations, developed with the support of the Spanish Agency for International Development Cooperation (AECID), represents a major step forward for the PAHO/WHO Strategy, since it explores ways of implementing regional mechanisms with free and equitable access to information and knowledge sharing. These initiatives aim to advance the goals of more informed, equitable, competitive, and democratic societies, where access to health information is considered a basic right. This publication is one of the instruments used by PAHO/WHO to develop the initiatives outlined in the Strategy, which coincides with the global eHealth strategy. One of the fundamental needs for the improvement of eHealth is the dissemination of information, and PAHO/WHO is assuming a leading role in this effort. The development of this new electronic publication is a key step in disseminating information that will be useful for decision makers on applying these technologies for the health of the Americas. This electronic book is one of the products of PAHO/WHO’s project: “eHealth Conversations: Using Information Management, Dialogue, and Knowledge Exchange to Move Toward Universal Access to Health.” Participants in these conversations included experts on electronic health and other specialties. Through virtual dialogues, the experts contributed with knowledge and reflections on the present and the future of eHealth in the Americas, analyzed the situation, and made recommendations for the implementation of electronic health initiatives. These recommendations are not only intended for PAHO/ WHO, but also for governments and the private sector. The aim of the project is to guarantee the convergence of local, national, and regional initiatives regarding the adoption and application of ICTs for public health, with special attention on critical issues in this field. It also intends to strengthen individual and collective capacities of health workers and institutions, connecting them in a network of on-line health networks, as well as to reinforce the PAHO/WHO eHealth program.Acknowledge the Spanish Agency for International Development Cooperation (AECID) for its financial support in preparing this publication and developing the project titled “eHealth Conversations: Using Information Management, Dialogue, and Knowledge Exchange to Move Toward Universal Access to Health;

Enhanced Living Environments

This open access book was prepared as a Final Publication of the COST Action IC1303 “Algorithms, Architectures and Platforms for Enhanced Living Environments (AAPELE)”. The concept of Enhanced Living Environments (ELE) refers to the area of Ambient Assisted Living (AAL) that is more related with Information and Communication Technologies (ICT). Effective ELE solutions require appropriate ICT algorithms, architectures, platforms, and systems, having in view the advance of science and technology in this area and the development of new and innovative solutions that can provide improvements in the quality of life for people in their homes and can reduce the financial burden on the budgets of the healthcare providers. The aim of this book is to become a state-of-the-art reference, discussing progress made, as well as prompting future directions on theories, practices, standards, and strategies related to the ELE area. The book contains 12 chapters and can serve as a valuable reference for undergraduate students, post-graduate students, educators, faculty members, researchers, engineers, medical doctors, healthcare organizations, insurance companies, and research strategists working in this area
