Implementación de un ambiente de simulación basado en software libre para el estudio de la provisión de servicios de comunicaciones en redes vehiculares ad-hoc mediante el uso de nodos móviles virtuales

Abstract

The high variability of the movement of the nodes in VANETs, which do not contain a central device that does the job of network administrator, has made it difficult the development of routing algorithms. However, Prof. Nancy Lynch Computer Science and Artificial Intelligence Laboratory at MIT have introduced the notion of virtual node -abstract nodes that move in a predetermined manner- which generate a virtual layer on which deploy communications services and decrease the problem of inefficient routing. Thus, each virtual node covers a region of a physical rack. Virtual nodes are supported collectively by real nodes, of which chooses a leader node. In this paper, we present the choice of leading node on VANET virtual node, which was implemented on platforms ns-2 and SUMO.
