Cyber-physical System Based Reliability Enhancement Mechanism for Vehicular Emergency Warning System

What is it about?

In order to improve the quality of the EWM propagation,this paper proposes an Optimal Transmission Reliability Enhancement Mechanism (OTREM) for the development of the cooperative driving systems. Our OTREM creates the strategy of the vehicular role change using the modified finite automata as the solution to the above EWM transmission problems. The experimental analyses show the proposed approach can significantly decline transmission delays, improve propagation accuracy, lessen EWM redundancy and raise propagation rates of EWM.

Why is it important?

The aim of this paper is to develop a novel OTREM of VANET to overcome the transmission problems of EWM for the cooperative driving in the intersection vicinity. Depending on vehicular cyber-physical systems, vehicular locations and EWM types, the vehicular role transition mechanism is developed to timely and accurately propagate EWM to the moving vehicles. It discusses the optimization algorithm for the analysis of EWM errors and transmission delays. Also, the improved finite automata is used to design a scheme of the vehicular role transition for EWM redundancy decline.
