Vehicular Ad Hoc Network (VANET) is an emerging field of technology that allows vehicles to communicate together in the absence of fixed infrastructure. The basic premise of VANET is that in order for a vehicle detect other vehicles in the vicinity. This cognizance, awareness of other vehicles, can be achieved through beaconing. In the near future, many(More)
Although current layered network architectures (mainly TCP/IP stack) have enabled internetworking of lots of different devices and services, they are neither well-suited nor optimized for the ubiquitous service provisioning required for the Future Internet. Hence, we firmly believe that we should have an underlying network architecture providing the(More)
—: Existing wireless networks aim to provide information communication services between mobile nodes. As a mobile node move between different radio networks, a handover process is needed to change its point of attachment to the predicted radio network. Since traditional (based on one metric Received Signal Strength Indicator) predictions of handover(More)
With the proliferation of multimedia capable devices, media services have to deal with heterogeneous environments where very different types of terminals wish to receive content anywhere and anytime. This situation motivates the appearance of multimedia services that adapt contents to the specific context of users. However, current Internet architecture is(More)
Internet is evolving fast thanks to the rising of new services and applications. This situation allowed realizing about current Internet deficiencies. Nowadays, researchers are proposing novel Internet architectures avoiding the rigidity of the layered structure posed by the TCP/IP stack. Service Oriented Architectures (SOA) principles are appropriate for(More)
Video communication VANETs has many applications, such as emergency video transmission or inter-vehicle entertainment. However, delivering video to high mobile vehicles faces challenges such as packet loss due to intermittent connectivity and channel variations. Thus, designing a reliable approach for video streaming over such harsh scenarios is needed.(More)
The inclusion of the organizations into the knowledge economy requires reorganization that allows them to integrate the knowledge in their conventional operation in order to convert it in a true strategic active. Developing new knowledge and knowledge management oriented to competences, strategies, structures, and processes is essential to support the new(More)
The popularity of P2P video streaming is raising the interest of broadcasters, operators and service providers. Concretely, mesh-pull based P2P systems are the most extended ones. Despite these systems address scalability efficiently, they still present limitations that difficult them to offer the same user experience in comparison with traditional TV.(More)
Internet is becoming a huge heterogeneous and dynamic network that is growing beyond its architectural limits. The scaling up of the number of communicating nodes and services is leading the Internet to an architectural crisis which in turn makes it difficult to provide services efficiently considering the requirements and context conditions of users.
