“…Similar shortcomings exist in works [31]- [35]. In [36], a 2-D Markov chain is proposed to model each AC in the station. The simulation results show that this model is valid for four access categories of traffic.…”

“…To be precise, in the latter case, when the channel becomes idle, the station has to verify if the channel stays idle during the AIFS period and decrements the backoff counter at the end of AIFS. Since the nodes have packets belonging to the same AC, the channel won't become busy during an AIFS, hence the backoff counter is decremented with the probability 1 (9.d-e) [23], [24]. When the packet is transmitted, the post-backoff procedure is taken regardless of the channel and the queue states (9.f).…”

“…Ma et al [22] presented a backoff model of DCF in order to analyse the broadcast saturation performances. Huang et al [23] modeled the Enhanced Distributed Coordination Function (EDCA) of IEEE 802.11e for saturated nodes by taking account of internal collisions. Han et al [24] studied EDCA for IEEE 802.11p with four access categories (ACs) by also taking account of internal collisions.…”

With the advancements in the autonomous vehicle technology, studies on applicability of the IEEE 802.11p and the related protocols for the autonomous driving applications are needed. In this paper, we study the impacts of vehicular communication on platooning control considering that the ETSIstandardised message set Cooperative Awareness Message (CAM) and the IEEE 802.11p are used for both the platooning and cooperative awareness applications. We first develop a theoretical model for the probability of a successful CAM transmission over IEEE 802.11p between platoon members by taking account of the existence of non-platoon vehicles on the road. The model is verified by comparing against simulation results obtained from the NS3 simulator. Finally, we investigate the impacts of the communication performance on the behaviour of platoons, specially the chain stability, when hundreds of vehicles share the wireless channel. The theoretical model reveals that thanks to the capture effect, communications between platoon members drastically outperform communications between arbitrary two vehicles on the road. The simulation results show that in contrast to an adaptive cruise control (ACC), which does not use vehicular communication, the IEEE 802.11p based vehicle to vehicle (V2V) communication aids for realizing stable platoons in highway scenarios.

This paper proposes an analytical model for the throughput of the Enhanced Distributed Channel Access (EDCA) mechanism in IEEE 802.11p MAC sub-layer. Features in EDCA such as different Contention Windows (CW) and Arbitration Interframe Space (AIFS) for each Access Category (AC), and internal collisions are taken into account. The analytical model is suitable for both basic access and the Request-To-Send/Clear-To-Send (RTS/CTS) access mode. The proposed analytical model is validated against simulation results to demonstrate its accuracy.
