“…The behavior of DSRC under vehicular blockage was studied statically in a parking lot as well as dynamically in urban, suburban and highway scenarios [7]. A recent work [5] also used logged data with multiple testing vehicles to study the performance of DSRC as a function of the distance between the transmitter and the receiver. Controlled lab testing is also useful in studying the congestion scenario [8] because a high number of transmitters can be easily achieved under lab setting and other variables can be controlled properly.…”

Abstract-Dedicated Short Range Communication (DSRC) was designed to provide reliable wireless communication for intelligent transportation system applications. Sharing information among cars and between cars and the infrastructure, pedestrians, or "the cloud" has great potential to improve safety, mobility and fuel economy. DSRC is being considered by the US Department of Transportation to be required for ground vehicles. In the past, their performance has been assessed thoroughly in the labs and limited field testing, but not on a large fleet. In this paper, we present the analysis of DSRC performance using data from the world's largest connected vehicle test program-Safety Pilot Model Deployment lead by the University of Michigan. We first investigate their maximum and effective range, and then study the effect of environmental factors, such as trees/foliage, weather, buildings, vehicle travel direction, and road elevation. The results can be used to guide future DSRC equipment placement and installation, and can be used to develop DSRC communication models for numerical simulations.Index Terms-DSRC, VANET, Vehicle-to-infrastructure communication I. INTRODUCTIONedicated short-range communication (DSRC) supports short range and reliable data communication between vehicles and with infrastructures to enable a number of safety, mobility, and energy applications [1]. A set of Basic Safety Messages (BSM) has been defined in SAE J2735 to ensure safety critical messages such as vehicle position, velocity, headway, and deceleration are broadcasted at a frequency of 10Hz. In the European Union, the Cooperative Awareness Messages (CAMs) have been specified in an ITS standard [2].Extended from IEEE 802.11a wireless communication protocol, which was designed for short range, low mobility, indoor use, IEEE 802.11p [3] is designed to meet the requirements of longer range (up to 1 km), extremely high mobility, and rapidly changing channel conditions. Because of these differences, DSRC operates at a higher frequency band, between 5.850 GHz and 5.925 GHz. This band is "dedicated" by the US Federal Communications Commission (FCC) for intelligent transportation system applications, to reduce the possibility of interference with other wireless devices [4]. Since one of the major purposes of DSRC is safety, reliable communication is critical.

“…Some of them are conservative as in the case of algorithms for controlling the shaper at DCC-ACC (such as AIMD -Additive Increase Multiplicative Decrease [38]); others are more innovative, as the idea of including position/context information in DCC decisions [39], also discussed within the Glove project. 10 Under the perspective of autonomous driving, threatening the channel saturation with cooperative messages of larger size, the adaptation could jointly operate on the rate, the transmission power, and the size (and content) of the broadcasted messages [40].…”

“…A functionally equivalent metric has been introduced independently in [14] under the name Neighborhood Awareness Ratio. Here, the cardinality of the set of known vehicles around a vehicle i is defined as ND i,r,t under the assumption of a circular neighborhood area with radius r and a beacon lifetime of t. This value is divided by the total number of actual neighboring vehicles under the same assumptions NT i,r,t , i.e.…”

A B S T R A C TVehicular Ad Hoc Networking (VANET) technology is, at it's core, the simple idea of outfitting vehicles with wireless data communication equipment for automatic information exchange. This technology is expected to serve as a foundation for a set of novel safety, automation, and infotainment applications. The most prominent among these applications are expected to be driver assistance systems which also support advanced levels of automated driving. These applications stand to benefit from enhanced situational awareness, which is made possible through the cooperative exchange of information about environmental influences and the presence and condition of surrounding vehicles.Wireless networking technology and networking in general are well understood domains in computer science. However, the context of connected vehicles and the associated requirements and communication patterns imposes a set of unique challenges, which require solutions that differ from established networking practices. The susceptibility of wireless communication to packet loss and the very high mobility of vehicular communication nodes make VANET technology extremely volatile. At the same time the usage in safety critical applications demands very low latency and high availability of the communication infrastructure for frequent information exchange. And on top of these challenges security and privacy need taken into account in the design of the overall communication infrastructure. Classic solutions for stable networks cannot provide optimal performance characteristics under these conditions. The focus of this work is specifically on vehicle-to-vehicle technology (V2V), which is a subset of the more general vehicle-to-anything (V2X) topic. This subset of VANET is concerned with the direct information exchange among vehicles without the involvement of additional infrastructure, which may or may not be available to vehicles which driving. Direct V2V communication is expected to always be available between vehicle within a safety critical range. Therefore, this communication path is expected to be used to enable the most safety critical applications.The scalability of security solutions for vehicular communication remains an untested aspect of ongoing efforts to bring VANET technology to the market on a larger scale. Filed operational test projects have started to trial VANET deployments to investigate, but penetration rates are too low to allow for realistic extrapolations of future scalability problems. This dissertations contributes to the research efforts that support the development of secure vehicular communication techv nology through investigations of attributes and solutions for scalable security for V2V broadcast communication.Part II reviews security requirements and provides detailed quantifications of performance requirements for security in V2V broadcast communication. These requirements define the solution space for applicable broadcast authentication techniques. Additionally, the review of achievable security and pr...
