A Highly Secured QoS Aware Routing Algorithm for Software Defined Vehicle Ad-Hoc Networks Using Optimal Trust Management Scheme

Recent reports show that the millions of people killed each year in the road accidents are due to high density vehicles and traffic environment. The road traffic safety has been an unsolvable problem in recent population. Generally, nodes in vehicle ad hoc networks have a relatively high speed, while there is a major issue to provide the accurate data transmission between two nodes. Many research works have been undertaken to solve these issues by trust based techniques. In this paper, a highly secured QoS aware routing algorithm (HSQ-RA) using optimal trust management scheme is proposed. In HSQ-RA, the multi-hop clustering is performed by improved whale optimization algorithm and the inter-cluster routing is done using the trust values. The multiple constraints are used to calculate the trust of each node and optimized by the trust search algorithm. The simulation result exhibits that the proposed HSQ-RA algorithm provides better quality of service (QoS), delivery rate, faster way to discover routing and reduce loss rate.
