Diseño de un protocolo para redes tolerantes a retardos: RTaDAP

Abstract

[EN] In last years the European Commission has decided to make an e ort in order to improve road tra c security. One of the main lines which this e ort is divided in is the Intelligent Transportation System technology, which aims to increase e cient and security of road tra c using new communication techniques. The number of techniques used for this purpose varies from vehicular ad-hoc networks to cellular mobile networks. Inside this wide range of protocols and technologies we have focused in delay tolerant networks and how it can be applied to vehicular networks facing the intermittent connectivity due to rapid changes of its topology. We have studied the proposed protocols and identi ed the main gaps needed to be lled in them, joining all this gaps and trying to ll most of them we have designed, developed and tested our own DTN protocol based on tra c route topology awareness called Road Topology and Destination Aware Protocol (RTaDAP). Testing results, based on simulations, shown that our protocol behaves better than well known DTN protocols under some conditions but presents some problems that must be solved in future.
