Adaptive decision making for improving trust establishment in VANET

In existing trust establishment researches, the decision making accuracy and decision delay of received event message are both the outstanding problems in VANETs. Especially on the decision delay, the delay of alert event might lead to traffic accident and injury. In this paper, we propose an adaptive decision making model which can make decision quickly by the effective and quick assistance of the RSUs. To evaluate the detection accuracy and efficiency of our proposed system, we conducted several simulations under different trust attacks. In the experiment results, the purpose model can shorten decision delay while raising the detection accuracy.
