Cooperative vehicular safety systems are expected to revolutionize the driving experience by providing road safety applications based on incident detection. Two vital quality parameters for cooperative safety applications are the position accuracy and communication reliability of the status information. The receiver may take erroneous decisions if the received data does not correspond to the latest situation of the transmitter (e.g., position, velocity, and trajectory of the target vehicle). In this paper, we propose and evaluate a POSition-ACCuracy (POSACC) based adaptive beaconing algorithm for cooperative vehicular safety systems. POSACC integrates three different control mechanisms to guarantee specific performance metrics. It adopts the position accuracy and communication reliability as the highest priority metrics, due to their direct impact on the vehicle's systems capability to avoid potential traffic accidents in real-time. In addition, it guarantees the priority metrics, maintaining the vehicle's warning distance, channel load, and end-to-end latency into the operative range of cooperative safety applications. POSACC is compared with three different state-of-the-art adaptive beaconing algorithms; ETSI DMG, LIMERIC, and DC-BTR&P. Extensive evaluation results show that POSACC successfully controls the beacon rate, transmission power, and the size of the minimum contention window. Simulation results also demonstrate that POSACC is more effective than the benchmark algorithms by guaranteeing the operational requirements of cooperative safety applications in a wider range of traffic situations.

Cooperative safety applications aim to detect potential crashes on the road and to notify vehicles in advance. The communication on these systems relies on the IEEE 802.11p [2] radio access technology in the 5.9 GHz frequency band, which specifies the mediumaccess-control (MAC) and physical (PHY) layers of Wireless Access in Vehicular Environments (WAVE) [3]. The IEEE 802.11p MAC layer is based on the Carrier Sense Multiple

“…The fast and successful propagation of emergency messages among the vehicles is very crucial as the lives of nearby citizens are dependent on it. Broadcasting the emergency messages to surrounding vehicles in advance can help reduce the number of traffic accidents [6], [7]. It is very important to design transmission methods for emergency messages especially in the case of large scale VANETs [8].…”

The number of vehicles on the roads has increased proportionally over the last couple of years and this number is likely to rise due to the increase in population growth and the number of vehicles that are manufacturing every day. This high traffic density leads to several problems, from which effectively disseminating the emergency messages is a major concern. Keeping in view the dynamic characteristics of VANETs, significant challenges are faced in disseminating the message across the network. The major challenges are the broadcast storm problem, hidden node problem and the packet collision. Many studies have been performed to devise an effective and reliable mechanism for disseminating emergency messages in a Vehicular ad-Hoc Network (VANET). Researchers have proposed different models to tackle various types of scenarios for emergency message dissemination. This paper not only reviews some recent contributions to emergency message dissemination in vehicular networks but also discusses various proposed methods based on Intelligent Transportation System (ITS), Internet of Things (IoT), Priority messaging, Clustering approach, Software Defined Network (SDN) and Fog Computing. We have also tried to explore the latest developments in emergency message dissemination using 5G networks.

Summary Due to the ad hoc nature of vehicular ad hoc networks (VANETs), routing in VANETs is challenging. Using an energy‐efficient shortest path without congestion (EESPWC) increases routing efficiency by satisfying specific parameters (high throughput, high packet delivery ratio, low overhead, low end‐to‐end delay, low packet loss ratio, and low energy consumption). In this work, enhanced distance and residual energy‐based congestion aware ant colony optimization (EDR‐CAACO) for VANETs is proposed to find an EESPWC. The proposed EESPWC produces high throughput and high packet delivery ratio with low overhead and low delay. In EDR‐CAACO, the roulette wheel selects the EESPWC based on the link's fitness values. The fitness value is computed based on the pheromone level of the link. The enhanced ACO (ant colony optimization) of the proposed model relies on the distance, residual, and congestion levels of the vehicles to estimate pheromone levels. For path selection, the roulette wheel relies on links that have the highest fitness value. The combination of high fitness value links provides an energy‐efficient non‐congested shortest route. The simulation results prove that the overall performance of EDR‐CAACO is better than Improved Distance Based Ant Colony Optimization Routing (IDBACOR), Fuzzy‐based Ant colony optimization (F‐ANT), ant colony optimization routing algorithm (ARA), and AntNet in terms of throughput, routing overhead, packet delivery ratio, end to end delay, and packet loss rate.
