A trusted routing protocol based on Bayesian in VANET

The particularities of the high dynamic, temporary meeting make the trust and cooperation between vehicles more difficult. To solve this problem, by using trust management model of Bayesian and in the light of the three kinds of opportunistic routing forwarding model, this paper puts forward a trusted routing protocol in VANET Based on GeoDTN+Nav routing protocol. The proposed protocol not only improves the security of routing, but also has the lower time complexity. Experimental results and analysis show that the proposed protocol has achieved good performance in the removal ratio of malicious nodes, correct reception ratio of packet and the message payload.
