“…The main idea for typical contention-free solutions is that vehicles are grouped into a cluster in which the cluster head is responsible for allocating time division multiple access (TDMA) slots to other cluster members [11], [23], [24]. As for typical contention-based solutions, the networking parameters, such as the beacon frequency, beacon dwelling time, transmit power and contention window size, are adjusted adaptively in accordance with the changing traffic conditions to achieve better system performance [9], [10], [14], [25]- [30]. For example, the Adaptive Traffic Beacon (ATB) protocol in [31] adjusts the beacon rate based on two key metrics: message utility and channel quality.…”

Abstract-Recent studies have shown that traffic safety and efficiency can be substantially improved by vehicle platooning, in which vehicles periodically broadcast their kinetic status to neighbors, known as beacon message dissemination. As a networked control system, vehicle platoon has attracted significant attention from both the control and networking areas. However, few studies consider the practical traffic scenario with both platoons and individual vehicles, and the proposed beaconing schemes lack the deep understanding of relationship between the beaconing performance and the requirements of the control mechanism. To address these challenging issues, we propose a joint controlcommunication design to achieve reliable vehicle platooning in a more realistic traffic scenario, wherein the traffic consists of both platoons and individual vehicles, and both periodic beacon messages and event-based safety messages shall be delivered together. Specifically, we first develop a comprehensive control-theoretical analysis to understand how the vehicular communication can affect features of platoon driving; based on the understanding, we then propose and analyze an adaptive platoon-based message dissemination scheme; finally, we conduct extensive numerical experiments to validate the effectiveness of the protocol and to confirm the accuracy of the our theoretical analysis.

“…Addressing this issue, Chen et al (2009b) suggest to scheduling the beacon generation only during the CCH interval, in order to avoid the problem of synchronous collisions at the start of the CCH interval. Other researchers (Campolo et al, 2011;Song et al, 2011) propose to randomise the transmission of the beacons during the CCH. Chrysostomou et al (2012) described an adaptive MAC contention control scheme where it is proposed to dynamically adapt the CW size based on the estimated contention conditions of the CCH channel.…”

Wireless access in vehicular environment employs the IEEE 802.11p/1609.4 standard wherein a multichannel architecture is envisioned to concurrently support both time-sensitive safety-related applications and value-added entertainment services. Although a standard now, the IEEE 802.11p protocol has known shortcomings of not being capable of providing reliable broadcast services. To address this issue, clustering-based enhanced safety message dissemination MAC protocol (CESD-MAC) is proposed in this paper which is an enhancement over the existing IEEE 802.11p/1609.4 protocol. CESD-MAC adopts mobility aware clustering and channel access scheduling. It rules out the concept of switching between the control channel and the service channel as implemented in the legacy standard. Simulation results are presented to verify the effectiveness of the proposed protocol and comparisons are made with the existing IEEE 802.11p MAC. The results demonstrate the superiority of CESD-MAC in terms of reduction of end-to-end delay, and increased throughput, channel utilisation and packet delivery ratio (PDR).Keywords: channel switching; clustering; contention window; DSRC; dedicated short-range communications; IEEE WAVE 1609.4; IEEE 802.11p; MAC; medium access control; multichannel; QoS; quality of service; safety; V2V; vehicle-to-vehicle; VANET; vehicular ad hoc network.Reference to this paper should be made as follows: Gupta, N., Prakash, A. and Tripathi, R.

“…Song et al [98] investigated the case that all safety messages generated during SCHI are rush to access as soon as the CCHI starts, which causes the flash crowd problem for the safety applications. To alleviate the adverse effect, a distributed periodic access scheme is proposed by using a hashing function to distribute the access time of the safety messages into CCHI instead of SCHI.…”

Abstract-Vehicles on the road with some common interests can cooperatively form a platoon-based driving pattern, in which a vehicle follows another one and maintains a small and nearly constant distance to the preceding vehicle. It has been proved that, compared to driving individually, such a platoon-based driving pattern can significantly improve the road capacity and energy efficiency. Moreover, with the emerging vehicular adhoc network (VANET), the performance of platoon in terms of road capacity, safety and energy efficiency, etc., can be further improved. On the other hand, the physical dynamics of vehicles inside the platoon can also affect the performance of VANET. Such a complex system can be considered as a platoon-based vehicular cyber-physical system (VCPS), which has attracted significant attention recently. In this paper, we present a comprehensive survey on platoon-based VCPS. We first review the related work of platoon-based VCPS. We then introduce two elementary techniques involved in platoon-based VCPS: the vehicular networking architecture and standards, and traffic dynamics, respectively. We further discuss the fundamental issues in platoon-based VCPS, including vehicle platooning/clustering, cooperative adaptive cruise control (CACC), platoon-based vehicular communications, etc., and all of which are characterized by the tight coupled relationship between traffic dynamics and VANET behaviors. Since system verification is critical to VCPS development, we also give an overview of VCPS simulation tools. Finally, we share our view on some open issues that may lead to new research directions.Index Terms-Platoon, Cyber-physical system (CPS), Vehicular ad-hoc network (VANET), Platoon-based vehicular communications, Cooperative adaptive cruise control (CACC), Simulator.
