A novel TT-SHO QoS aware and secured Vehicular Adhoc Network (VANET) routing protocol for smart intelligent transportation

Vehicular Ad-hoc Networks (VANET) has attracted many researchers in recent days because of its inevitable applications in smart transportation structure, autonomous vehicles and Internet of Vehicles (IoV). Establishing and maintaining secured end to end connections in a VANET is challenging due to the dynamic changing environment and due to malicious vehicles. To overcome this problem, this paper proposes novel secured protocol TT-SHO which integrates the Tent Tuned Spotted Hyena Optimization (TT-SHO) for routing algorithm and Hybrid Chaotic Encryption for secured data transmission. The proposed routing protocol adopts the TT-SHO for shortest path optimization and transmits the chaotic encrypted data in the shortest path by maintaining the Quality of Services (QoS). The experimentation is carried out in terms of latency (5 ms), Packet Delivery Ratio (PDR) (90), throughput (1 bps) and also compared with existing frameworks. Final results proved that the proposed TT-SHO with Hybrid Chaotic Encryption is suitable for VANET environment by providing safe, reliable and robust data transmission. And the model proves that it provides more reliable secured data transmission by maintaining QoS.
