Vehicle density in VANET Applications

This paper analyzes how street-level traffic data affects routing in VANETs applications. First, we offer a general review about which protocols and techniques would fit best for VANET applications. We selected five main technical aspects (Transmission, Routing, Quality of Service, Security and Location) that we consider are differential aspects of VANETs from current Ad-Hoc Networks. Second, the paper analyzes how to configure each technical aspect according to the goal of a wide range of VANET applications. Third, we look at the routing aspect in depth, specifically focusing on how vehicle density affects routing, which protocols are the best option when there is a high/low density, etc. Finally, this research implements a sensor technology, based on an acoustics sensor that has been deployed around the city of Xalapa in México, to obtain reliable information on the real-time density of vehicles. The levels of density were discretized and the obtained data samples were used to feed a traffic simulator, which allowed us to obtain a global picture of the density of the central area of the city. According to the specific levels of vehicle density at a specific moment and place, VANET applications may adapt the routing protocol in a real-time wayPeer ReviewedPostprint (published version

Competencias en TIC e informacionales como agentes de cambio para los docentes del siglo XXI

El Laboratorio Nacional de Informática Avanzada A. C. (LANIA), apoyado de un Fondo Mixto del CONACyT se ha dado a la tarea de desarrollar un Diplomado en Competencias de Tecnologías de Información y Comunicación e informacionales (TIC) para docentes de Educación Básica. En el marco de la Reforma de la Educación Básica, el diplomado pretende impulsar competencias informacionales y de TIC que coadyuven con el desarrollo integral de un docente preparado para interactuar con las necesidades el siglo XXI; un docente capaz de desarrollar capacidades en el uso de la información que, por un lado impacte su forma de vivir, trabajar, aprender, enseñar y compartir estas nuevas competencias, y por otro posibilite la formación de ciudadanos informados capaces de contribuir con sus entornos. El desarrollo de este diplomado está pensado en tres etapas 1) Diseño; 2) Desarrollo; e 3) Implementación. En este documento mostramos el resultado de la Revisión del Estado del Arte de la incorporación de TIC en el Aula y competencias informacionales relacionadas, parte medular de la fase relativa al Diseño del Diplomado. Al término del documento y como resultado del análisis de la revisión de literatura presentamos las competencias informacionales y de TIC que un docente preparado para enseñar en el mundo digital debe tener.Palabras claves: competencias TIC; formación de profesores; tecnología digital; revisión de literatura
