Power Controlled Adaptive Range Radar for Self Driving Vehicles

Interference among self driving vehicles (SDVs) has become a serious problem due to the extensive growth of radar based connected vehicles (CVs). Since the driving resources (i.e., frequency and/or time slots) for these radar sensors are limited, a large value of radar range in a high traffic density may interfere large number of surrounding vehicles, while a small radar range in the low traffic density may lose the opportunity to detect the surrounding vehicles. In this paper, we have proposed traffic-based dynamic range approach (TDA) for SDVs equipped with radar sensors. TDA ensures that the range of radar vary in such a way that SDVs must be able to detect the objects in its vicinity as well as the vehicle may not interfere the surrounding vehicles. Moreover, we have compared the performance of TDA with the fixed range approach (that is considered as baseline approach for this paper). Simulation results show that TDA outperforms the fixed range baseline approach.
