Design and simulation of a collision notification application with geocast routing for car-to-car communications

Abstract

Introduction: Car-to-X Communications are envisioned to improve road safety, traffic efficiency, and information services through short-range and real-time systems. The enabling applications have varied requirements such as low latency, specific forwarding patterns, and reliable data exchange between vehicles and infrastructure. Hence, a cross-layer architecture for vehicular applications should be defined according to the goals of the implementation, so as to consider proper routing and dissemination mechanisms, communication protocols, and the application’s design and operation. Methods: In this context, we propose the characterization of the upper layers of a safety-oriented Car-to-Car application

A Deep Review and Analysis of Data Exchange in Vehicle-to-Vehicle Communications Systems: Coherent Taxonomy, Challenges, Motivations, Recommendations, Substantial Analysis and Future Directions

“…Other benefits related to the safety of V2V communication systems are focused on urban road conditions and development of control strategies in the presence of congestion where the behavior of one vehicle influences the other [137]; and notification of neighbouring vehicles of hazardous conditions, such that drivers can take actions during and before emergency situations [48], [96]. Other studies provide drivers with relevant information about the environment surrounding their vehicle, which can make driving safe and easy [53]; and solutions that assess the risk of finding ice on the road [6], enable efficient use of existing road infrastructure, reduce road congestion and lower fuel consumption [27], [133], and increase road throughput [52].…”

“…The next step is to develop precollision systems that can warn the driver and take control of the car to avoid potential collision and ensure interactions among all vehicles, not only a select subset [28], [54], [59]. Road traffic safety applications, infotainment applications and decisions for collision avoidance and SC need to address accurate information because broadcast communication does not allow mechanisms, such as sending request to send/clear to send and acknowledgements that can be considered among the most critical vehicular services [3], [22], [37], [48], [85], [89], [112], [125].…”

“…Other issues are testing for malicious nodes [97] and addressing privacy issues [60]. Advances in information and communication technologies allow the transportation community to foresee relevant improvements for the incoming years in terms of efficient, environmentally friendly and safe traffic management [1], [48]. By combining the usage of loop detectors and traffic cameras, the regional traffic management authority can achieve near real-time detection of potential incidents in practice, which is ideal for detecting situations, such as icy roads or animals on the road [4].…”

“…This section briefly describes the devices used in previous experiments of methodological aspects. Vehicles are equipped with the IEEE 802.11p DSRC [2], [3], [8], [32], [34], [48], [90], [98] or LTE [50] to provide V2V communication using Bluetooth [95], Raspberry Pi board [33], [124], [129] and standard ETSI with ITS-G5 [8], [30]. An implementation of V2V communication paradigm using Arduino Mega board is performed by connecting WiFi to Arduino using Wiznet W5100 Ethernet to SPI converter [29], using the Mono-camera of MobilEye mounted behind the windshield to provide relative measurements (distance, angle and relative speed) [7] and equipping with a WLANp MK5 OBU module from Cohda Wireless [8], [32].…”

Monitoring of moving objects in the absence of a GSM signal

“…Technologies for receiving and transmitting digital information are used for remote positioning of mobile objects, monitoring vehicle parameters and the condition of drivers, monitoring and analyzing logistics services, and managing them [1,2,3,4,5,6].…”
