The dynamic nature of vehicular ad hoc networks (VANETs) requires efficient routing protocols for better performance. It is challenging to provide a universal routing protocol that performs well in all scenarios of VANETs. A routing protocol is challenged by vehicle speed, position, and network density. VANETs for highways are dependent on speed and direction of vehicles thus requiring customized routing protocols. This paper presents a novel direction and relative speed (DARS)-based routing protocol for highways using a single-hop packet forwarding approach. It selects the next hop using DARS of the vehicle. The experiments show significant improvement in packet delivery ratio, end-to-end delay, packet drop ratio, and Jain's fairness index for proposed protocol compared to direction-based ad hoc on demand distance vector.
