Sporadic Learning Networks (SLNs) are social learning networks between people (students, teachers and experts) that are in a common place or connected through Internet or some communication network. The idea is to establish dynamic learning networks that encourage their members to work together and create a learning environment with resources and activities adequate to meet their learning needs. This...
Internet, combined with the technologies of communication and information (ICT), is changing the society. Most aspects of the life of each individual have been influenced by this technological revolution. Education is not indifferent to this reality, since a number of tools and applications have been created which seek to improve the learning process. However, these educational technologies do not...
The use of digital filters as the Wavelet Transform is widely recognized in signal processing; however, for the analysis of an electroencephalographic (EEG) signal, the most optimal filter to be used has not been definitively determined. This work presents a comparison between the results obtained by filtering an EEG signal recorded during an 8 minute foreign language class on 69 asymptomatic volunteers...
The number of elderly people in the world is growing rapidly. For this reason, is necessary more tools for the care, entertainment, and interaction of the elderly. This paper presents an application to foment social interaction among elderly people. This app is part of the SAFER platform, focused on meeting the needs of this part of population. The app stores in a database the profiles of the elderly...
Many routing algorithms for vehicular ad-hoc networks have relied on geographic forwarding as a means to reduce the paths' sensitivity to individual vehicle movements. In recent years, the basic forwarding strategies have been refined to create road-based paths, connecting successive road intersections selected on the basis of the connectivity between them. Revisiting this idea, we present two different...
Collaborative downloading of contents from the Internet in VANETs has become a hot research topic. In traditional schemes, most of the vehicles are interested in the same content which is splitted in multiple chunks that are collaboratively downloaded by the nodes and finally delivered to the rest of vehicles over a peer-to-peer network. This paper proposes a collaborative downloading scheme for VANETs...
Many information services envisaged for the future of vehicle communications rely on the wired Internet infrastructure to download content from remote servers, and then on peer-to-peer, opportunistic networking to deliver the content to the pertinent nodes. We present an approach to support individualized access to web contents from vehicular ad hoc networks, based on a virtualization layer that engages...
Cloud-based Mobile Augmentation (CMA) is aimed to increase the computing capabilities of handheld devices for enabling the execution of resource-intensive mobile applications. In order to avoid latencies and excessive bandwidth consumption, the most recent CMA approaches borrow the augmentation resources from proximate clusters of handheld devices which do remain immobile, being their mobility an...
The scenarios envisaged for the paradigm of vehicular cloud computing (VCC) have been limited by the challenges derived from the mobility of the vehicles, to the point that most of the proposals in the literature merely deal with vehicles in parking lots, stuck in traffic jams or moving as a flock for a long time. We present an approach to overcome those limitations by engaging the vehicles in collaboration...
