“…Such issue consequently leads to the packet loss problem which has been regarded as a major challenge in the vehicle platooning system (Jia et al, 2015). To further explore the system performance in case of the packet loss, we first identify the beacon performance under the specification of the IEEE 802.11P and WAVE 1609.4 with a similar methodology proposed in Campolo and Vinel (2011).…”

Recent developments of information and communication technologies (ICT) have enabled vehicles to timely communicate with each other through wireless technologies, which will form future (intelligent) traffic systems (ITS) consisting of so-called connected vehicles. Cooperative driving with the connected vehicles is regarded as a promising driving pattern to significantly improve transportation efficiency and traffic safety. Nevertheless, unreliable vehicular communications also introduce packet loss and transmission delay when vehicular kinetic information or control commands are disseminated among vehicles, which brings more challenges in the system modelling and optimization. Currently, no data has been yet available for the calibration and validation of a model for ITS, and most research has been only conducted for a theoretical point of view. Along this line, this paper focuses on the (theoretical) development of a more general (microscopic) traffic model which enables the cooperative driving behaviour via a so-called inter-vehicle communication (IVC). To this end, we design a consensus-based controller for the cooperative driving system (CDS) considering (intelligent) traffic flow that consists of many platoons moving together. More specifically, the IEEE 802.11p, the de-facto vehicular networking standard required to support ITS applications, is selected as the IVC protocols of the CDS, in order to investigate how the vehicular communications affect the features of intelligent traffic flow. This study essentially explores the relationship between IVC and cooperative driving, which can be exploited as the reference for the CDS optimization and design.

“…However, these theoretical works [5], [6], [7] only considered either non-fading channel or fading channel with a constant bit error rate (BER) regardless of node position. Moreover, they assumed that collision always causes transmission failure, which is not necessarily the case in real wireless environments because of the capture effect * 1 .…”

Abstract:The reliability of Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) vehicle-to-vehicle (V2V) communication in real road environments suffers from fading, shadowing and the hidden terminal problem, especially for non-line-of sight (NLOS) areas such as intersections. In order to improve the communication reliability, a CSMA/CA based vehicle-roadside-vehicle broadcast relay network was proposed and its effectiveness has been shown through simulations. However, the potential of such a network has not been well analyzed and optimized. In this paper, a theoretical model is proposed to analyze the performance of the broadcast relay network in detail. In order to fit real vehicular environments, the model assumes a typical crossroad and takes into account fading, shadowing, the hidden terminal problem and the capture effect. The influence of system parameters including position of nodes, carrier sense threshold and RF frequency band on the reliability of the network is studied based on the model. The accuracy of the proposed analytical model is confirmed by simulations. The analytical model and the obtained results are useful for the design of vehicular broadcast networks to select appropriate system parameters.

“…Recently, the use of medium access control (MAC)-layer broadcast messages in safety-related mechanisms has received a great deal of attention, especially within the context of vehicular ad hoc networks (VANETS). VANET applications span from emergency services, such as road safety and driver assistance applications, to automatic crash notication or hazardous road condition reports [9,10,11,12,13,14]. Because of that, the issue of reliable delivery of broadcast messages within a given deadline has become a major concern [15].…”

“…As aplicações das VANETs vão desde os serviços de emergência, tais como aplicações de segurança nas rodovias e de assistência ao condutor, até a noticação automática de acidentes ou informações sobre o estado das estradas [9,10,11,12,13,14]. Devido a isso, o problema de entrega conável de mensagens de difusão dentro de um determinado prazo tornou-se uma grande preocupação [15].…”

O transmissor é um usuário secundário (SU) que acessa o canal usado pelos usuários primários de forma oportunista. O protocolo de controle de acesso ao meio usado é o Slotted-Aloha onde uma transmissão por difusão tem sucesso se todos os nós receptores, dentro do alcance de transmissão do emissor, recebem a mensagem dentro do prazo de entrega denido previamente. Uma abordagem com re-transmissão de mensagens é utilizada para melhorar a conabilidade da entrega, que necessita ter uma taxa de sucesso maior ou igual a 99,9 %, com uma latência máxima de 100 ms para cumprir as regulamentações de segurança das redes veiculares. Além disso, um novo método de análise de transmissão periódica é proposto usando uma abordagem com coecientes multinomiais e outra baseada na função de distribuição de probabilidade geométrica. ABSTRACTThis work analyses an optimal random access for broadcasting messages with deadline in a cognitive radio (CR) network considering that the message must be delivery to all nodes in the network in a strict known delivery time. The transmitter is a secondary user (SU) that accesses the primary users (PUs) channel opportunistically. The slotted-Aloha medium access control (MAC) protocol is considered assuming that a successful broadcast transmission from a SU happens if all the receiver nodes within the SU transmission range receive the SU message within a given deadline.A re-broadcast approach is used to improve the reliability of the message delivery which requires a probability of success greater than or equal to 99.9% with a latency of 100 ms. Also a novel method of analysis for periodic broadcast using multinomial coecients is introduced, as well as a method that considers a geometric distribution approach.
