Abstract: To avoid a frequent communication link failure and to provide a trusted routing among the vehicles, we are proposing an Optimized Node Selection Routing Protocol of VANET using a trust model. The proposed routing protocol is designed to find the optimized node for the transmission of data from the source node to the destination to achieve a trusted communication and high packet delivery ratio. To prove the performance of proposed routing protocol, performance metrics such as packet delivery ratio and end to end delay are evaluated and compared with existing routing protocols using ns2.
