Design and simulation of a collision notification application with geocast routing for car-to-car communications
(Springer Verlag, 2015-12-01) Orozco, Ana María
Introduction: Car-to-X Communications are envisioned to improve road safety, traffic efficiency, and information services through short-range and real-time systems. The enabling applications have varied requirements such as low latency, specific forwarding patterns, and reliable data exchange between vehicles and infrastructure. Hence, a cross-layer architecture for vehicular applications should be defined according to the goals of the implementation, so as to consider proper routing and dissemination mechanisms, communication protocols, and the application’s design and operation. Methods: In this context, we propose the characterization of the upper layers of a safety-oriented Car-to-Car application.
Mobile ad-hoc routing protocols survey for the design of VANET applications
(IEEE, 2012-08-30) Michoud, Roger
Vehicular communications are considered as a key factor to improve road safety and enhance urban mobility. The design and deployment of Vehicular Ad hoc Networks (VANETs) involve several decision criterias that lead the research into new challenging tasks to be solved. Routing mechanism is a fundamental component for the success of any vehicular application; the particular features of VANETs - a highly dynamic topology, links frequently disrupted and a fragmented network - require an efficient, robust and scalable routing strategy for each application. In this paper, we present a survey of routing protocols and we also provide a simulation testbed that will be used to assess the performance of the selected protocols. © 2012 IEEE.
Redes vehiculares Ad-hoc: aplicaciones basadas en simulación
(2012-01-01) Orozco, Ana María
Recent research efforts of academia, automotive industry and transport government sector point to intelligent transportation systems (ITS) as a key technology for improving road safety, traffic efficiency and comfort driving. Vehicular ad hoc networks (VANET) have significant potential to enable applications in order to enhance traffic safety. The interaction among vehicles and infrastructure allows real-time communications that provide information to drivers in hazardous situations, avoiding accidents. This article provides an overview of vehicular ad hoc networks; describes the fundamental concepts, communication standards and vehicular applications. In addition, this paper presents an evaluation of VANET simulators.

Recent research efforts of academia, automotive industry and transportation sector point to Intelligent Transportation Systems as a key technology for improving road safety, traffic efficiency and comfort driving. Vehicular Ad Hoc Networks (VANETs) have significant potential to enable applications for traffic safety efficiency transportation and sustainable mobility. The dissemination methods and routing mechanisms play an essential role in the design and characterization of vehicular applications. This article provides an overview of vehicular ad hoc networks; we describe the fundamental concepts, communication standards and vehicular applications. This paper also presents a survey on routing protocols for VANETs and simulation results for Distributed Robust Geocast.
