Estudio de algoritmo de encaminamiento ad hoc en redes vehiculares

Abstract

En los Sistemas de Transporte Inteligente (ITS – Intelligent Transport Systems), las Redes Ad Hoc Vehiculares (VANET - Vehicular Ad Hoc Networks) vendrán a convertirse en una realidad que cambiará el paradigma del transporte. Las VANET derivan de las MANET: redes autorganizadas cuya topología cambia continuamente debido a la movilidad de los nodos, con ciertas características propias como la alta movilidad y la velocidad de los vehículos. El diseño de protocolos de enrutamiento serán avalados por los diferentes estudios y simulaciones necesarias para poder calificar su eficiencia ante cambios en la topología y el movimiento rápido de los nodos. Se presentará una breve clasificación de los protocolos de enrutamiento existentes en VANET. En este trabajo se presentará la propuesta de un algoritmo de enrutamiento, que será comparado con otros ampliamente utilizados y normalizados por la IETF: AODV y OLSR, según unas métricas bien definidas. Finalmente, se expondrán conclusiones y líneas futuras. [EN] In Intelligent Transport Systems (ITS), Vehicular Ad Hoc Networks (VANET) will become a reality that will change the transport paradigm.

The design of routing protocols will be supported by the different studies and simulations necessary to qualify their efficiency in the face of changes in the topology and rapid movement of the nodes. A brief classification of the routing protocols existing in VANET will be presented. This paper will present the proposal of a routing algorithm, which will be compared with others widely used and standardized by the IETF: AODV and OLSR, according to well-defined metrics. Finally, conclusions and future lines will be presented.
