Abstract

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). The proposed secure routing protocol aims to address the inherent limitations in VANET routing, particularly the challenges associated with mobility metrics and the incorporation of trust metrics. By leveraging a comprehensive trust framework that integrates both direct and indirect observation-based reputation systems, the protocol enhances the robustness and reliability of the routing process. In addition, a similarity-based evaluation method is employed to assess the validity of recommendation messages, facilitating the selection of the most trusted and reliable path. 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.
