Reliability improvement in Clustering-Based vehicular Ad-Hoc network

Abstract

Clustering based vehicular Ad-hoc Network (CAN) is being considered as the most viable solution to integrate milimeter wave (mmWave) and sub-6 GHz interface in vehicular communication. In CAN, the data path contains two cascaded links, mostly mmWave link for vehicular to vehicular (V2V) connectivity and sub-6 GHz link for vehicular to infrastructure (V2I) connectivity. In this letter, we have introduced diverted path approach (DPA) to enhance V2V communication reliability. In addition, the notion of back-up link has been introduced to enhance V2I communication reliability. Then, through simulation results, it is shown that DPA can significantly improve V2V communication reliability. Further, it is shown that the incorporation of both the proposed schemes with the existing CAN, significantly enhances the overall vehicular (V2V+V2I) communication reliability.
