A Survey of Green Networking Research
Reduction of unnecessary energy consumption is becoming a major concern in
wired networking, because of the potential economical benefits and of its
expected environmental impact. These issues, usually referred to as "green
networking", relate to embedding energy-awareness in the design, in the devices
and in the protocols of networks. In this work, we first formulate a more
precise definition of the "green" attribute. We furthermore identify a few
paradigms that are the key enablers of energy-aware networking research. We
then overview the current state of the art and provide a taxonomy of the
relevant work, with a special focus on wired networking. At a high level, we
identify four branches of green networking research that stem from different
observations on the root causes of energy waste, namely (i) Adaptive Link Rate,
(ii) Interface proxying, (iii) Energy-aware infrastructures and (iv)
Energy-aware applications. In this work, we do not only explore specific
proposals pertaining to each of the above branches, but also offer a
perspective for research.Comment: Index Terms: Green Networking; Wired Networks; Adaptive Link Rate;
Interface Proxying; Energy-aware Infrastructures; Energy-aware Applications.

An architecture for distributed ledger-based M2M auditing for Electric Autonomous Vehicles
Electric Autonomous Vehicles (EAVs) promise to be an effective way to solve
transportation issues such as accidents, emissions and congestion, and aim at
establishing the foundation of Machine-to-Machine (M2M) economy. For this to be
possible, the market should be able to offer appropriate charging services
without involving humans. The state-of-the-art mechanisms of charging and
billing do not meet this requirement, and often impose service fees for value
transactions that may also endanger users and their location privacy. This
paper aims at filling this gap and envisions a new charging architecture and a
billing framework for EAV which would enable M2M transactions via the use of
Distributed Ledger Technology (DLT)
Análisis urbano y comunidades inteligentes: “una aproximación al empleo de la tecnología en la movilidad cotidiana”
Concentration of population in urban centers
is a global problem for which different strategies in
order to organize different processes in cities and improve
the quality of life are required. The creation of
smart communities is shown as a sustainable solution
since they deal with various key aspects, such as traffc
management and mobility, through the use of information
technologies (ITs). This work presents a review of
recent studies using information technologies for urban
analysis and mobility in cities. A descriptive analysis
of automated methods for collecting and analyzing citizens’
mobility patterns is performed; it is centered in
smart card use, geolocation and geotagging. It is concluded
that a robust communication infrastructure, supported
by an effcient computational platform allowing
big data management and ubiquitous computing, is a
crucial aspect for urban management in a smart community.La concentración de la población en los centros
urbanos es una problemática mundial que requiere de estrategias
que permitan organizar sus procesos y mejorar
la calidad de vida. La creación de comunidades inteligentes
se muestra como una solución sostenible, debido a que
éstas trabajan aspectos claves para el desarrollo urbano,
como la gestión de tráfco y la movilidad, apoyada en las
tecnologías de la información (TICs). Este trabajo presenta
una revisión del estado del arte en cuanto a la aplicación
de las TICs al análisis urbano y movilidad ciudadana. Se
analizan descriptivamente diversos métodos automáticos
para la recolección y el análisis del patrón de movilidad de
los ciudadanos, enfocándose en el uso de tarjetas inteligentes,
geolocalización y geoetiquetado. Se encuentra que una
infraestructura de comunicaciones robusta, apoyada en
una plataforma computacional ágil con manejo de grandes
datos y computación ubicua, es primordial para la gestión
urbana en una comunidad inteligente
