Abstract-Video over vehicular networks continues to receive warranted attention, with envisioned applications having the potential to present entirely new opportunities and revolutionise existing services. Many video systems have been proposed, ranging from safety to advertising. We propose a novel system for VANETs, namely the TArgeted Remote Surveillance (TARS) module for the existing Greedy Perimeter Stateless Routing (GPSR) protocol which permits multiple mobile vehicles to request and receive live video feeds from vehicles within a select geographic region. The multi-hop, vehicle-to-vehicle system enables mobile units to surveil a target area in real time by leveraging the dashboard cameras of vehicles moving within the target region. We combine several proposed extensions to the core protocol to introduce a dynamic real time congestion aware clustering scheme to achieve this. Our proposed system is compared against existing routing protocols using mobility data from Nottingham. GPSR-TARS outperforms the protocols assessed in key criteria crucial for meeting the quality of service demands of live multimedia dissemination.

“…[Rosário et al 2014] propõem o protocolo XLinGO, o qual considera parâmetros de múltiplas camadas para cálculo de DFD, tais como tamanho do buffer, qualidade do enlace, localização e energia. [Quadros et al 2015] apresentam um mecanismo para calcular o DFD baseado em parâmetros do vídeo, localização e QoE. Contudo, uma VANET tem topologia de rede altamente dinâmica com baixo tempo de contato, ocasionando frequentes desconexões.…”

“…Dessa forma, diversos protocolos de roteamento para a comunicação de Veículo para Veículo (V2V) foram propostos para atender à exigência de entrega vídeo em VANET [Liu et al 2016]. Contudo, a transmissão de vídeo com suporte a QoE em uma VANET é uma tarefa difícil devido às frequentes desconexões causadas pelas mobilidades dos veículos [Quadros et al 2015]. Por exemplo, [Uppoor and Fiore 2012] analisou um registro de mobilidade em uma rodovia da cidade de Colônia na Alemanha e concluiu que a maioria dos veículos têm contatos extremamente curtos, variando entre 1 e 15 segundos.…”

As redes veiculares (VANETs) oferecem uma ampla gama de serviços multimídia que vão de segurança e avisos de tráfego a vídeos de entretenimento e publicidade. Contudo, a transmissão de vídeo em tempo real em uma VANET tem rigorosos requisitos de Qualidade de Experiência (QoE), além de topologia de rede altamente dinâmica com baixo tempo de contato. Para mitigar tais problemas, os veículos próximos que se deslocam no mesmo sentido e que desejam cooperar podem agrupar-se para formar um pelotão e, assim, os veículos irão movimentar-se com velocidade semelhante. Nesse contexto, este artigo apresenta um mecanismo baseado em teoria dos jogos para formação de pelotão denominado de TJ2P, o qual possibilita a transmissão de vídeo com suporte a QoE. O mecanismo TJ2P seleciona veículos com velocidades similares e uma distância apropriada para formar o pelotão. Resultados de simulações constatam a eficiência do mecanismo TJ2P em garantir a transmissão de vídeo com QoE adequado, sem aumentar o consumo de combustível e emissão de CO2, em comparação aos protocolos BLR e XLinGO.

“…Yoo et al [47] devised an efficient opportunistic relay protocol that exploits multiuser diversity and effectively copes with the dynamic channel, where the choice of a relay vehicle involves the tradeoff between the transmission range and throughput. Quadros et al [48,49] introduced the Quality of Experience (QoE)-driven and link-quality receiver-based protocol to allow live video dissemination, where the QoE-driven parameters are offered for the relay node selection and backbone maintenance, enhancing the capacity of the system in delivering QoE-aware videos. As far as we know, the routing path lifetime has not been taken into consideration on the multihop multimedia content transmission scheme design, which will be unfolded in this paper.…”

Large volume content dissemination is pursued by the growing number of high quality applications for Vehicular Ad hoc NETworks(VANETs), e.g., the live road surveillance service and the video-based overtaking assistant service. For the highly dynamical vehicular network topology, beacon-less routing protocols have been proven to be efficient in achieving a balance between the system performance and the control overhead. However, to the authors’ best knowledge, the routing design for large volume content has not been well considered in the previous work, which will introduce new challenges, e.g., the enhanced connectivity requirement for a radio link. In this paper, a link Lifetime-aware Beacon-less Routing Protocol (LBRP) is designed for large volume content delivery in VANETs. Each vehicle makes the forwarding decision based on the message header information and its current state, including the speed and position information. A semi-Markov process analytical model is proposed to evaluate the expected delay in constructing one routing path for LBRP. Simulations show that the proposed LBRP scheme outperforms the traditional dissemination protocols in providing a low end-to-end delay. The analytical model is shown to exhibit a good match on the delay estimation with Monte Carlo simulations, as well.
