A Collision Alleviation Scheme for IEEE 802.11p VANETs

Wireless Personal Communications, 2010
IEEE 802.11p protocol, also known as Wireless Access for the Vehicular Environment provides dedicated short range communication for future Vehicular Ad Hoc Networks (VANETs). According to the IEEE 802.11p standard, the highest priority traffic transmission often suffers from the consecutive collisions in bursty arrival or congested scenarios because of

Channel Estimation Schemes for IEEE 802.11p Standard

IEEE Intelligent Transportation Systems Magazine, 2013
In vehicle-to-vehicle (V2V) communications, reliable channel estimation is critical for the system performance due to the extremely time-varying characteristic of V2V channels. In this article, we present a survey on the current channel estimation techniques for the IEEE 802.11p standard. According to deficiencies of the current schemes and considering

Characterization and Performance Evaluation of IEEE 802.11p NICs

Proceedings of the 1st ACM MobiHoc Workshop on Technologies, mOdels, and Protocols for Cooperative Connected Cars, 2019
The automotive industry is scrambling to equip high- and middle-segment vehicles with communication capabilities that will enable the commercialization of connected vehicles in the near future. Although both IEEE and 3GPP are developing new solutions, it is likely that IEEE 802.11p will be the protocol of choice.

A distributed algorithm for virtual traffic lights with IEEE 802.11p

2014 European Conference on Networks and Communications (EuCNC), 2014
A virtual traffic light (VTL) is a mechanism that allows vehicles to autonomously solve priorities at road junctions in the absence of fixed infrastructures (i.e., conventional traffic lights). To develop an effective VTL system, communication between vehicles is a crucial factor and can be handled either using cellular infrastructure or adopting a ...

IEEE 802.11p: Laboratory measurements and analysis

2011 50th FITCE Congress - "ICT: Bridging an Ever Shifting Digital Divide", 2011
The IEEE 802.11p amendment to the ubiquitous IEEE 802.11 standard has been recently published. It addresses some modifications to the Medium Access Control (MAC) and physical layers to better suit the requirements of communications between moving vehicles.

Jamming and interference vulnerability of IEEE 802.11p

2014 International Symposium on Electromagnetic Compatibility, 2014
The IEEE 802.11p standard will in the next years be introduced for vehicle-to-vehicle and vehicle-to-infrastructure (V2X) communication. Some of the services in this standard are dedicated to active road safety applications and can therefore be sensitive to radio interference.

Real-world evaluation of IEEE 802.11p for vehicular networks

Proceedings of the Eighth ACM international workshop on Vehicular inter-networking, 2011
This paper presents a set of experiments, performed using an IEEE 802.11p physical layer implementation based on the open-source ath5k driver, in both line of sight (LOS) and non-line of sight (NLOS) conditions. The results are compared against theoretical models and simulation of the same scenarios with proper propagation and channel models.

Performance study of IEEE 802.11p in blind corner scenario

2016 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2016
In present, IEEE 802.11p is a standard for vehicle communication which can enhance quality of road transportation. The communication in non-line-of-sight is an important scenario that has to be inspected deeply. Because in non-line-of-sight or blind corner scenario, the signals may be obstructed.

PResync: A method for preventing resynchronization in the IEEE 802.11p standard

2015 IEEE Symposium on Computers and Communication (ISCC), 2015
Vehicular networks are seen as the basis for the development of intelligent transportation systems. Therefore, and in order to take advantage of the benefits from these transportation systems, the development of standards that meet the specific characteristics of vehicular networks was required.
