The Utility of DSRC and V2X in Road Safety Applications and Intelligent Parking: Similarities, Differences, and the Future of Vehicular Communication

Abstract

As the technological advancement in the automotive field increases and the complexity of vehicle and infrastructure applications is extremely high, new directions and approaches are needed in this field. Supporting and developing vehicular applications dedicated to road safety by analyzing the current behavior of existing networks in various forms is imperative. This paper studies and implements a DSRC-type communications infrastructure that receives a set of controllable and adjustable indicators, which can provide messages to network drivers in a timely manner. The implementation is based on the 802.11p protocol and initially addresses pedestrian infrastructure or pedestrian safety, controlled areas, and perimeters that allow intelligent communications. The design and setting of the communication parameters in the lower layer of the DSRC stack for vehicle applications are part of this work, aspects that are also relevant in the case of autonomous vehicles.

Optimal model of vehicular ad-hoc network assisted by unmanned aerial vehicles and information-centric networking to enhance network performance

“…The network nodes are the vehicles which are already employed in a VANET architecture. Vehicles are equipped with OBUs allowing them to communicate with each other via V2V mode or with the road infrastructure composed of RSUs (static or mobile) using V2I mode [18]. OBU also includes a GPS sensor to track its position and has memory to store and retrieve information using the standard IEEE 802.11p communication support.…”

“…Dedicated short-range communication (DSRC) is one of the most common wireless technologies used in V2V and V2I communication which is employed as a medium for short range communication [18]. The frequency communications commission (FCC) has assigned it a bandwidth of 75 MHZ at a frequency of 5.9 GHz [19].…”

Analysis and Estimation of Economic Influence of IoT and Telecommunication in Regional Media Based on Evolution and Electronic Markets in Romania

“…IoT progress is the creation of a bridge between the Internet and the network sensor infrastructure. Cavalcante et al [26] show that cloud computing addresses IoT exploitation by promoting tangible benefits to the economy, society, or the environment. Another IoT perspective is associated with the challenges of M2M communications operability, with a focus on networking features such as security, mobility, resource efficiency, addressability, and last but not least, routing [27].…”

Increasing Vehicular Visible Light Communications Range Based on LED Current Overdriving and Variable Pulse Position Modulation: Concept and Experimental Validation

“…One of the techniques that has gained increasing momentum in recent years is a subfield of Optical Wireless Communications (OWC), namely, Visible Light Communications (VLC) technology [ 5 , 6 ]. This effect comes as a result of the multiple advantages VLC has, such as the transmission of information in a range of unlicensed frequencies, the use of a spectrum about 1000 times greater than the current Radio Frequency (RF) spectrum, the possibility to use the already existing lighting and signaling Light-Emitting Diode (LED) systems with minimal modifications, and last but not least, the compatibility with other technologies that would ensure complementary advantages within hybrid platforms [ 7 , 8 , 9 ]. Although the performances obtained in recent years are encouraging, with results that a decade ago would have seemed improbable, some challenges still need to be addressed in the context of ensuring specific conditions in the field of road traffic, such as increasing the robustness to noise, the communication range, or further enhancing the mobility [ 2 , 5 ].…”
