This study presents the design and performance evaluation of a low-cost Vehicle-to-Vehicle (V2V) communication system utilizing HackRF One Software-Defined Radio (SDR) platform and GNU Radio to support Smart Transportation Systems (STS). The system employs omni-directional RP-SMA male antennas and operates frequency 2.7 GHz. It enables direct wireless data exchange between vehicles in both stationary and mobile scenarios. Field experiments were conducted to assess system performance under various inter-vehicle distances, vehicle speeds, and line-of-sight (LOS) conditions. Performance metrics including packet loss, bit error rate (BER), and signal-to-noise ratio (SNR) were evaluated. The results show that communication reliability is strongly influenced by vehicle mobility, distance, and environmental obstructions. In stationary and unobstructed conditions, the system achieved optimal performance, with 0% packet loss, zero BER, and an SNR of approximately 13.93 dB at distances up to 11 meters. Under mobile conditions, the best performance was observed at a distance of 5 meters, where packet loss ranged from 1.4% to 2.8%, BER remained in the order of 1.0e-5, and estimated SNR values ranged from 11.8 dB to 10.5 dB. These findings demonstrate the feasibility of implementing SDR-based V2V communication systems for smart mobility and highlight the importance of optimizing system parameters for dynamic and obstructed environments. © 2025 IEEE.
