SVC-HT: Secure Vehicular Ad hoc Communications using Hybrid Trust

Because of the nature and characteristics of conveying significant level road security and enhanced traffic the executives, vehicular networks are turning into a key report subject under the intelligent transportation system (ITS). Weighty correspondence gear is introduced under vehicles, which requires a powerful stock, an on-board handling system, and information stockpiling gadgets. To keep up with and further develop the traffic signal system, an assortment of remote correspondence advances is utilized. The ITS can offer types of assistance to traffic specialists as well as security precautionary measures for drivers and travelers. Multiple ways for discussing security and protection issues for vehicle ad hoc networks (VANETs). In this paper, novel routing protocol called Secure VANET communications using Hybrid Trust (SVC-HT) is proposed to protect the communications from the malicious vehicles in the network. We integrated the hybrid trust approach with the clustering mechanism to improve the VANET performances. The proposed SVC-HT consists of two phases such as attacker detection with Cluster Head (CH) selection and reliable route formation for secure data transmission. The experimental outcomes of SVC-HT protocol are compared with three recent VANET protocols in terms of average throughput, Packet Delivery Ratio (PDR), delay, and overhead. The results of SVC-HT outperformed the existing protocols.
