Bezier Curve based Multipath Routing in VANET

Abstract

In VANET environment multipath routing protocols enhance reliability and fault tolerance. However major drawback of the existing multipath protocols is that all the computed paths are not utilized for communication at any given time. Hence this work proposes Bezier Curve based Multipath Routing (BCMR) in VANET. The proposed work computes multiple paths from source to given destination using cubic Bezier curves and more notably engage all or more than one path during the actual communication. Proposed work performs better w.r.t. parameters like packet delivery ratio, transmission time and path discovery time.
