“…Also, we have incorporated the path loss propagation exponent, γ, derived in a least-square (LS) sense adopting a classical log-distance path loss model for longer Tx-Rx distances than d 0 . Note that the values of the path loss exponent are higher, in both frequency bands, than the reported for convoy traffic in the same environments [5], [6]. …”

“…In addition to the radio frequency equipment, the Tx and Rx vehicle were equipped with GPS receivers to provide information about the acquisition time of measurements, as well as the Tx-Rx distance. More details about the measurement setup and configuration of the SA and VNA, omitted here due to space restrictions to 2 pages, can be found in [5], [6].…”

“…Several V2V studies of the path loss propagation based on measurement campaigns have been conducted over the past few years [1]- [6]. These measurement campaigns have been carried out at the 5.9-GHz dedicated short-range communications (DSRC) frequency band, or adjacent bands, e.g., at 5.3 and 5.8 GHz.…”

“…These measurement campaigns have been carried out at the 5.9-GHz dedicated short-range communications (DSRC) frequency band, or adjacent bands, e.g., at 5.3 and 5.8 GHz. Nevertheless, with the exception of Fernández [6], Sevlian [7], and Yoshida [8], there have not been published results at the opening 700-MHz frequency band, recently adopted by Japan for the development of intelligent transportation system (ITS) applications. In both frequency bands, the measurements are mainly focused on convoy situations, i.e., Tx and Rx vehicles driving in the same direction (convoy traffic).…”

In this work, we investigate the path loss propagation of the vehicular-to-vehicular (V2V) channel when the vehicles are driving in the opposite direction. The investigation is based on narrowband channel measurements at 700 MHz and 5.9 GHz carried out in different environments under real road traffic conditions, i.e., rural, highway, suburban and urban environments. The results show that there is a path loss offset between the forward and reverse directions, which is related to the environment. Also, we provide mean values of the path loss propagation exponent showing that are higher than the values derived when the vehicles are driving in the same direction. These results should be considered for a proper simulation and design of the future V2V communications systems.

A vehicular network with Road Side Units (RSUs) provides an efficient way to connect vehicles even on the move. However, due to high deployment and maintenance cost of RSUs, it is necessary to use lesser number of RSUs such that total cost is minimized. It is suggested that cellular networks such as LTE are capable of fulfilling the demands posed in vehicular network scenarios. Availability of high bandwidth, large coverage area, and low latency are some of the advantages of cellular networks which help in overcoming the challenges of high speed vehicular communication. In this paper, we propose a maiden approach to analyse the performance of a vehicular network with cellular infrastructure as a backbone. For this, we use mobile femto access points as relays in place of RSUs. We model the network using M/M/m queue and compare the delay and throughput performance with traditional IEEE 802.11p vehicular networks. We also formulate an optimization problem and propose a subchannel power control algorithm to handle increased co-channel interference which emerges due to high mobility of vehicles in the network. Our suggested approach shows improvement in terms of delay, throughput, and energy efficiency. The results are verified using extensive simulations.Index Terms-Vehicular network, cellular network, mobile femto access points, delay, energy efficiency.

Summary This paper proposes transmission power control for vehicular ad hoc network (VANET) using fuzzy system. Despite the potential advantages of VANET especially for safety and intelligent transportation system, some challenges are discovered during the implementation of VANET. Main challenges emerge because of the dynamic environment and high mobility of vehicle. Furthermore, the interference due to the shared‐spectrum usage can significantly decrease the quality of signal. Fuzzy system is implemented to control the transmission power based on the signal to interference and noise ratio (SINR) difference with the targeted value of the receiver vehicle and the interference inflicted by the transmitter vehicle. The algorithm of fuzzy power control for VANET is proposed, and the performance is evaluated through the simulations. The results of simulations show that the proposed algorithm can increase SINR of vehicles especially the vehicles with SINR value below the target. Thus, the average of SINR and the throughput of the system can be increased as well.
