TL;DR: The demands for models to describe the radio channel inside and around vehicles at high frequencies are discussed and an appropriate ray tracing approach is presented.
Abstract: With the growing demand for wireless communication systems, a wireless concept for the data exchange between different system components inside a vehicle and also between vehicles becomes interesting. In order to describe and thus assess the mobile radio channel in and around the vehicle, simulations are required. For low frequencies, full wave simulations using the Method of Moments are adequate means. For higher frequencies, those models get inadequate because of their computational effort. Systems employing high frequencies are also used for car-to-car communication systems. The main aspect in such applications is the time variance of the scenario, as the vehicles move continuously and thus the channel impulse response is time-variant. This paper discusses the demands for models to describe the radio channel inside and around vehicles at high frequencies and presents an appropriate ray tracing approach.

TL;DR: Message exchange in VANETs should be secured through the use of a public-key infrastructural system, and several methods to meet this goal have been designed.
Abstract: Message exchange in VANETs should be secured. Researchers have designed many methods to meet this goal. One of the ways agreed upon by most researchers, is through the use of a public-key infrastru ...

TL;DR: This paper investigates the performance of multi-hop vehicular VLC networks based on the recent reference channel models and upcoming standards like IEEE 802.15.7r1 and 802.11bb.
Abstract: Majority of works in the field of vehicular visible light communication (VLC) networks are based on some ideal assumptions. Particularly, the ideal Lambertian pattern is assumed for channel modeling and only a simple point-to-point transmission link is considered in the network analysis. In this paper, we investigate the performance of multi-hop vehicular VLC networks based on the recent reference channel models and upcoming standards like IEEE 802.15.7r1 and 802.11bb. The impact of the asymmetrical radiation pattern of car headlamps, as well as the road reflectance are considered. In MAC layer, we deploy carrier-sense-multiple-access with collision-avoidance (CSMA/CA) as the medium-access protocol.

TL;DR: This work proposes a Secure and Lightweight Identity Management (SLIM) mechanism for vehicle-to-vehicle communications that is more secure in that it can defend more types of attacks in VANETs, and is more efficient in thatIt requires much shorter response time for identity verification between vehicles.
Abstract: Vehicular Ad-hoc Networks (VANETs) show a promising future of automobile technology as it enables vehicles to dynamically form networks for vehicle-to-vehicle (V2V) communication. For vehicles to securely and privately communicate with each other in VANETs, various privacy-preserving authentication protocols have been proposed. Most of the existing approaches assume the existence of Road-Side Units (RSUs) to serve as the trusted party during the authentication. However, building RSUs is costly and may not be able to capture the speed of the deployment of the VANETs in the near future. Aiming at minimizing the reliance on the infrastructure support, we propose a Secure and Lightweight Identity Management (SLIM) mechanism for vehicle-to-vehicle communications. Our approach is built upon self-organized groups of vehicles which take turns to serve as captain authentication unit to provide temporary local identities for member vehicles. While ensuring the vehicles’ identities are verifiable to each other, we also prevent any vehicle in VANETs including the captain authentication unit from seeing the true identities of other vehicles. The proposed authentication protocols leverage the public key infrastructure in a way that the key generation workload is distributed over time and hence achieve authentication efficiency during the V2V communication. Compared to the previous related work, the proposed SLIM mechanism is more secure in that it can defend more types of attacks in VANETs, and is more efficient in that it requires much shorter response time for identity verification between vehicles.

TL;DR: The routing protocol proposed in this paper is based on a multi-hop transfer of a single message by discovering the most suitable vehicle within the transmission range instead of using single hop broadcast (flooding) scheme which results in high packet loss and collision rate.
Abstract: Vehicle to vehicle communication has strong potential to be a mechanism to improve driver’s safety and is now emerging as a prominent research area all over the world. At present, vehicular networks are still not considered to be very efficient because of their rapid topology changes and their highly dynamic structure. However, there has been ongoing and progressive research and development in Vehicular Ad hoc Networks (VANETs) [1] [2] [3] to support vehicle to vehicle communication, particularly in the area of routing in VANETs. In VANETs, routing schemes to reduced overhead and resource consumption is required to ensure successful message transfer within the network. The routing protocol proposed in this paper is based on a multi-hop transfer of a single message by discovering the most suitable vehicle within the transmission range instead of using single hop broadcast (flooding) scheme which results in high packet loss and collision rate. The simulation environment used for proposed algorithm is a tool which combines both network simulator and traffic simulator, known as NCTUns-6.0.
