A Driving Path Based Opportunistic Routing in Vehicular Ad Hoc Network

Vehicular Ad Hoc Networks is a promising technology that can widely apply to monitor the physical world in urban areas. Efficient data delivery is important in these networks and optimal route selection is vital to improve this factor. Vehicular mobility is a reflection of human social activity and human trajectories show a high degree of temporal and spatial regularity. Therefore, vehicular driving paths are predictable in a large extent. A new opportunistic routing protocol (DPOR) is proposed in this study that uses driving path predictability and vehicular distribution in its route selection procedure. This protocol is composed of two phases: intersection and next hop selection phases. A utility function is calculated to select the next intersection and a new mechanism is also proposed for the next hop selection phase. Simulation results show that DPOR achieves high delivery ratio and low end-to-end delay in the
