报告摘要:

Traditional anti-jamming techniques are not always applicable in vehicular ad-hoc networks (VANETs) due to the high mobility of onboard units (OBUs) and the large-scale network topology. In this work, we use unmanned aerial vehicles (UAVs) to relay the message of an OBU and improve the communication performance of VANETs against smart jammers that observe the ongoing OBU and UAV communication status and even induce the UAV to use a specific relay strategy and then attack it accordingly. More specifically, the UAV relays the OBU message to another roadside unit (RSU) with a better radio transmission condition if the serving RSU is heavily jammed or interfered. In the anti-jamming UAV relay game, the UAV decides whether or not to relay the OBU message to another RSU. A hotbooting policy hill climbing (PHC)-based UAV relay strategy is proposed to help the VANET resist jamming in the dynamic game without being aware of the VANET model and the jamming model. Simulation results show that this scheme can efficiently reduce the bit error rate of the OBU message and thus increase the utility of the VANET compared with the Q-learning based scheme.
