Vehicular Ad-Hoc Networks can enhance road safety and enable drivers to avoid different threats. Safety applications, mobile commerce, and other information services are among different available services that are affected by dynamic topology, vehicle’s speed and node misbehaving. Dynamic topology makes the route unstable and unreliable. So, improving the throughput and performance of VANET through reliable and stable routes with low overhead are among the important goals in this context. Verifying all issues related to the reliable routing, different effective internal, external and environmental factors on route reliability are led to a new security framework in this paper. Black-hole attack and its effects, as the most well-known attack in wireless networks, along with presenting a secure routing protocol are other achievements of this paper. The proposed protocol uses a trust management system to detect and neutralize this type of attack. Simulation results show that the presented trust-based framework can increase the reliability of the networks by decreasing the effect of the malicious nodes in the routing process.
