Position Based Seamless Connectivity for Vehicular Ad Hoc Networks

Abstract

Vehicular ad hoc networks is one of the emerging fields in todays era. Both industry and academia are focusing their interest in coping up with the upcoming challenges in this field for providing enhance safety and infotainment services to the passengers. A heterogeneous wireless network architecture has been proposed to achieve communication among vehicles or communication between vehicles and infrastructure at any time and any where for efficient routing which improves the connectivity issues in vehicular ad hoc networks. A novel position based routing algorithm called PB-SCR (Position Based Seamless Connectivity Routing) has also been proposed to offer seamless connectivity to the passengers travelling on rural highways through heterogeneous wireless network architecture. This algorithm has been simulated using NS-2 simulator and evaluated the performance in terms of packet delivery ratio, end-to-end delay, and average path length. The results of PB-SCR are compared with AODV and GPSR routing protocols and shows significant performance improvement.
