In Vehicular Ad Hoc Networks (VANET), trust establishment among vehicles is important to secure applications' integrity and reliability. In general, trust levels can be evaluated by monitoring the behavior of neighboring nodes and their generated messages based on events. However, obstacles can create a case of None Line of Sight (NLOS), which will interrupt direct communication among vehicles and prevent vehicles from properly monitoring their neighboring nodes. In this paper, we propose a trust evaluation model based on location information and verification in a NLOS condition. The model provides a trust attribute for applications and services to evaluate their own trust levels. Simulation results showed improvement in neighborhood awareness and success rate of message delivery under the effect of moving obstacles.
