Objectives: To propose a suitable protocol that is secured and efficient for data transmission in Vehicular Adhoc Networks (VANET) environment. Methods/Statistical Analysis: The main challenge in VANET is to protect valuable information from the users. However there are many malicious vehicles that affect the system. To overcome this problem, the Secure and Intelligent routing (SIR) protocol is used that will transmit the data in shortest path through the authenticated vehicles. The proposed method makes use of message transmission, link connectivity and vehicle positioning to forward the data to the destination. Sending the data through the QoS based optimized path will enhance the performance of the system. Hence the proposed Enhanced Secure and intelligent routing (ESIR) protocol is QoS enabled and optimized. The QoS metrics taken into concern are delay, network load and distance with minimum number of hops. Particle Swarm Optimization (PSO) algorithm used for optimization in the proposed work takes one main parameter into concern; it is distance with minimum number of hops. Findings: The proposed technique is compared with the existing SIR protocol in terms of throughput, delay, packet delivery ratio, residual energy levels and packet drop. The results obtained show that the proposed technique serves as an efficient routing protocol for VANET environment providing a reliable and robust service.
