Secure opportunistic routing protocol in VANETs

In this paper, we introduce a new trusted opportunistic routing protocol called Trusted Context-aware Opportunistic Routing (TCOR) which produces a secured routing for VANET and it is incorporated with a recommendation mechanism (TCOR-Rec). OMNET++ is used to implement and simulate TCOR, which has proved its efficiency in comparison with other routing protocols (COR opportunistic protocol, AODV and trusted AODV). To simulate an adequate VANET environment and evaluate the protocols under realistic conditions, different metrics and network parameters such as the network traffic pattern, mobility pattern, and the fading propagation model have been used. The results have shown that TCOR and TCOR-Rec outperform traditional routing protocols by approximately 9% and 15%, respectively, in terms of packet delivery when the attacker nodes are involved in the network.
