Executive Summary

Vehicle-to-Vehicle (V2V) communication is a core technology for enabling safety and non-safety applications in next generation Intelligent Transportation Systems. Recently, several studies have shown that line of sight conditions have a direct influence on V2V link quality. Line of sight is influenced by both topographic features and vehicles located between the communicating nodes. It was shown experimentally that vehicles can obstruct the LOS communication up to 50% of the time; furthermore, a single obstructing vehicle can reduce the power at the receiver by more than 20 dB. Based on both experimental measurements and simulations performed using a validated channel model, the authors show that the elevated position of the antennas on tall vehicles improves communication performance.
