“…• Adjacent Channel Interference: The parallel usage of the Control CHannel (CCH) and the Service CHannels (SCHs) in order to increase the transmission rate and decrease the packet loss ratio impacts communication by generating interference signals. This problem is known as Adjacent Channel Interference (ACI) which has been evaluated for VANETs in [63].…”

Vehicular Ad-hoc NETworks (VANETs) have attracted a lot of attention in the research community in recent years due to their promising applications. VANETs help improve traffic safety and efficiency. Each vehicle can exchange information to inform other vehicles about the current status of the traffic flow or a dangerous situation such as an accident. Road safety and traffic management applications require a reliable communication scheme with minimal transmission collisions, which thus increase the need for an efficient Medium Access Control (MAC) protocol. However, the design of the MAC in a vehicular network is a challenging task due to the high speed of the nodes, the frequent changes in topology, the lack of an infrastructure, and various QoS requirements. Recently several Time Division Multiple Access (TDMA)-based medium access control protocols have been proposed for VANETs in an attempt to ensure that all the vehicles have enough time to send safety messages without collisions and to reduce the end-to-end delay and the packet loss ratio. In this paper, we identify the reasons for using the collision-free medium access control paradigm in VANETs. We then present a novel topology-based classification and we provide an overview of TDMA-based MAC protocols that have been proposed for VANETs. We focus on the characteristics of these protocols, as well as on their benefits and limitations. Finally, we give a qualitative comparison, and we discuss some open issues that need to be tackled in future studies in order to improve the performance of TDMA-based MAC protocols for vehicle to vehicle (V2V) communications.

Pre-crash warning is a core functionality in vehicular ad hoc networks (VANETS). To avoid accidents, each vehicle calculates the probability of a collision with any of its neighbors based on the received beacons. An accurate neighbor awareness requires a high beacon transmit rate, which leads to an overloaded communication channel in dense traffic scenarios. To reduce channel load and increase the accuracy of information for vehicles residing in critical situations, we propose a novel multi channel beaconing service based on a request/reply protocol. Based on simulations, we evaluate the proposed approach in low and high density scenarios. We show that the approach provides highly up-to-date information in safety critical situations, while still keeping the communication overhead low.

“…However, due to the high cost of the dual tranceivers devices and to the cross-channel interference problem, until now not properly investigated [18], [19], dual-radio devices are expected to be deployed as a long-term solution, while single-radio devices could be available in the early deployment stages of vehicular networks.…”

The 802.11p standard has been recently standardized to provide Wireless Access in Vehicular Environments (WAVE). A multi-channel architecture is envisioned to concurrently support both time-sensitive safety-related applications and value-added informative and entertainment services. According to the WAVE specifications, an alternating channel access scheme allows single-radio devices to tune into a common frequency during the control channel (CCH) interval, to exchange safety and control packets, and to subsequently switch to one of the available service channels (SCHs) for non-safety related data exchange. Broadcasting of short-lived packets is largely expected to be used on the CCH to deliver periodic status updates from vehicles and network initialization information. This paper investigates the joint impact of different packet generation patterns and contention window sizes on the delivery of broadcast packets on the CCH by accounting for WAVE channel switching under different traffic load conditions, data rate and packet size values.
