“…Moreover, the measurement was performed in rush hour conditions in order to integrate in a simple manner, the impact of obstructing vehicles on the received signal strength. The measurement equipment and parameter setup are described in detail within our previous work [17]. Furthermore, in order to model also the multi-path wave propagation caused by signal reflection or diffraction on surrounding buildings along the intersection, a ray-tracing tool is used to model the wave propagation by reproducing the measurement's scenario.…”

Although the potential of Vehicular Ad-Hoc Networks (VANETS) to improve road safety and traffic efficiency for next-generation vehicular traffic system has been well investigated and proved, the performance of vehicle-to-vehicle (V2V) communication, especially at urban intersections has not been clearly quantified. In this paper, we evaluate the effects of buildings on the vehicle-to-vehicle performance at urban intersections based on a profound simulation campaign. Due to the twodimensional nature of intersection topologies, we investigate the performance of V2V communication by analyzing packet delivery ratios and packet drop rates with respect to sender and receiver's position under varying node density and intersection layout. While stationary and mobile obstacles considerably attenuate the received signal power, the results reveal that the presence of buildings could in some situations improve the performance of V2V communication by reducing co-channel interference from hidden nodes.

“…The results also indicate a very limited transmission range at urban intersections under NLOS conditions due to densely placed buildings. Recently carried out V2V measurements that are currently prepared for publication substantiate these observations [4]. However, too short communication distances will not meet the requirements of potential safety-related applications like intersection collision warning.…”

The reliability of future vehicular communication systems suffers considerably in non line-of-sight (NLOS) situations due to poor signal-to-noise ratio (SNR) conditions. One strategy to increase the effective SNR at the receiver is to employ receive diversity techniques. Field trials with real vehicles and different antenna configurations are cost-intensive and require a lot of effort. By means of a simulation-based approach, this paper analyzes the performance benefit of receive diversity for vehicular communications using maximum ratio combining (MRC). The results can support developers and manufacturers during the design process of multiple-antenna solutions for vehicular communications.

Abstract-Traffic safety at road intersections can be improved by establishing reliable communications between vehicles. For vehicle-to-vehicle communications, this requires information exchange in non line-of-sight (NLOS) conditions due to the obstruction by buildings. In order to overcome the low receive signalto-noise ratio (SNR) due to NLOS, we consider to place a relay at road intersections to enhance the reliability of communication links. In this paper, we implement a vehicular non-stationary geometry based stochastic channel model for road intersections, which is an extension of an existing highway channel model. The model is verified by comparison with vehicular channel measurements. Using the proposed channel model, we present link level simulation results for IEEE 802.11p relaying at varying transmitter/receiver locations using different channel estimation techniques. The results show that a relay at the intersection is able to greatly extend the reliable communications region. Besides, in the high SNR regime with moderate or high mobility transmitter and receiver, the block type least square channel estimator is the bottleneck that limits the relaying performance. An advanced iterative channel estimator is also simulated, which exhibits robustness against increased vehicle velocities.
