En los últimos años han evolucionado extraordinariamente las comunicaciones móviles e inalámbricas, también las prestaciones de los terminales móviles de los usuarios y se han desarrollado servicios de datos y aplicaciones que requieren de una gran cantidad de recursos. A pesar de estos avances, poco se ha progresado en la calidad de servicio (QoS) y en la tarificación. Actualmente, mediante las tarifas planas existentes, se dispone de acceso de banda ancha; pero no se garantiza ningún parámetro de QoS. En este proyecto se especifican los mecanismos y parámetros de diseño que permitan desarrollar una alternativa al actual sistema de conexión best effort y tarifa plana; para poder disponer de QoS en los diferentes dispositivos móviles. Esta alternativa se basa en el diseño y desarrollo de un algoritmo que permita, a los usuarios, seleccionar el operador de red móvil más adecuado, según el tipo de servicio, entre todos los operadores de red móvil disponibles en el entorno. El terminal únicamente intercambia mensajes de señalización con las redes de comunicaciones móviles del operador seleccionado, siempre que los parámetros de QoS del operador cumplan con las especificaciones del nivel de servicio (SLS) acordadas en el acuerdo de nivel de servicio (SLA). En el momento que el operador de red seleccionado no cumpla con las SLS, el terminal deja de seguir al operador y ejecuta el algoritmo para encontrar un nuevo operador de red al que seguir. Una vez diseñadas las diferentes versiones del algoritmo, se han programado y simulado; para poder determinar qué métodos y parámetros son los más apropiados para crear el algoritmo que mejor se adapte a las distintas situaciones. Las simulaciones se han realizado con el simulador Network Simulator (NS-2). El algoritmo resultante es más eficiente en calidad y en tarificación que el sistema actual, ya que el algoritmo permite asignar de una manera mejor y más personalizada la QoS que los diferentes usuarios necesitan para efectuar correctamente los diversos servicios. El algoritmo también incrementa los beneficios de los operadores de red móvil, ya que se utiliza una tarificación variable de acuerdo a las calidades asignadas a cada usuario.

This book presents the fundamentals of wireless communications and services, explaining in detail what RF spectrum management is, why it is important, which are the authorities regulating the use of spectrum, and how is it managed and enforced at the international, regional and national levels. The book offers insights to the engineering, regulatory, economic, legal, management policy-making aspects involved. Real-world case studies are presented to depict the various approaches in different countries, and valuable lessons are drawn. The topics are addressed by engineers, advocates and economists employed by national and international spectrum regulators. The book is a tool that will allow the international regional and national regulators to better manage the RF spectrum, and will help operators and suppliers of wireless communications to better understand their regulators.

Based on twenty case studies of universities worldwide, and on a survey administered to leaders in 101 universities, this open access book shows that, amidst the significant challenges caused by the COVID-19 pandemic, universities found ways to engage with schools to support them in sustaining educational opportunity. In doing so, they generated considerable innovation, which reinforced the integration of the research and outreach functions of the university. The evidence suggests that universities are indeed open systems, in interaction with their environment, able to discover changes that can influence them and to change in response to those changes. They are also able, in the success of their efforts to mitigate the educational impact of the pandemic, to create better futures, as the result of the innovations they can generate. This challenges the view of universities as "ivory towers" being isolated from the surrounding environment and detached from local problems. As they reached out to schools, universities not only generated clear and valuable innovations to sustain educational opportunity and to improve it, this process also contributed to transform internal university processes in ways that enhanced their own ability to deliver on the third mission of outreach

From the bestselling author of the acclaimed Chaos and Genius comes a thoughtful and provocative exploration of the big ideas of the modern era: Information, communication, and information theory. Acclaimed science writer James Gleick presents an eye-opening vision of how our relationship to information has transformed the very nature of human consciousness. A fascinating intellectual journey through the history of communication and information, from the language of Africa’s talking drums to the invention of written alphabets; from the electronic transmission of code to the origins of information theory, into the new information age and the current deluge of news, tweets, images, and blogs. Along the way, Gleick profiles key innovators, including Charles Babbage, Ada Lovelace, Samuel Morse, and Claude Shannon, and reveals how our understanding of information is transforming not only how we look at the world, but how we live.

Designing Software Architectures will teach you how to design any software architecture in a systematic, predictable, repeatable, and cost-effective way. This book introduces a practical methodology for architecture design that any professional software engineer can use, provides structured methods supported by reusable chunks of design knowledge, and includes rich case studies that demonstrate how to use the methods. Using realistic examples, you’ll master the powerful new version of the proven Attribute-Driven Design (ADD) 3.0 method and will learn how to use it to address key drivers, including quality attributes, such as modifiability, usability, and availability, along with functional requirements and architectural concerns. Drawing on their extensive experience, Humberto Cervantes and Rick Kazman guide you through crafting practical designs that support the full software life cycle, from requirements to maintenance and evolution. You’ll learn how to successfully integrate design in your organizational context, and how to design systems that will be built with agile methods. Comprehensive coverage includes Understanding what architecture design involves, and where it fits in the full software development life cycle Mastering core design concepts, principles, and processes Understanding how to perform the steps of the ADD method Scaling design and analysis up or down, including design for pre-sale processes or lightweight architecture reviews Recognizing and optimizing critical relationships between analysis and design Utilizing proven, reusable design primitives and adapting them to specific problems and contexts Solving design problems in new domains, such as cloud, mobile, or big data
