Background: VANETs (Vehicular Ad-Hoc Networks) are the subclass of MANETs, which has recently emerged. Due to its swift changing topology and high mobility nature, it is challenging to design an efficient routing protocol for routing data amongst both moving vehicles and stationary units in VANETs. In addition, the performance of existing routing protocols is not effective due to high mobility characteristics of VANETs. Methods: In this paper, we proposed link reliable routing strategy that makes use of restricted greedy forwarding by considering neighborhood vehicles density and the least, average velocity with its own neighboring vehicles for the selection of next forwarder. Result: The proposed approach take the assumption that at every junction the police patrolling car (i.e. PCR junction node), which forwards the packet to vehicle onto correct road segment only. The link reliability is ensured by the mechanism for the selection of the next forwarder. Conclusion: The objective of this paper is to increase route reliability to provide increase throughput without greatly affecting end-to-end delay. The simulation results reveal that the proposed approach Reliable GPSR(R-GPSR) outperforms existing GPSR and E-GyTAR approach.

Abstract Vehicular ad-hoc network (VANET) plays a significant role in future intelligent transportation systems. The main objective of vehicular ad hoc networks (VANETs) is to improve driver safety and traffic efficiency. Many researchers proposed different schemes to improve communication efficiency. It is quite challenging where vehicles’ speed, Direction, and density of neighbors on the move are not consistent. Although several routing protocols have been introduced to manage data exchange among vehicles in VANETS, they still suffer from many drawbacks such as lost packets or time penalties. This paper introduced a new Fog Based Routing Strategy, which constructs a reliable system of adaptive, stable, and efficient routing networks. FBRS consists of two main phases: System Setup Phase (SSP) and System Operation Phase (SOP). SSP creates a cluster network, collects its nodes’ data, mining routes between them, and ranking paths using Dijkstra’s algorithm into a simplified table. Although, SOP generates a reliable route between the request of any two nodes for a communication channel and maintains the route against any simultaneous crashes. Recent VANET routing protocols have been compared against FBRS. Experimental results have proven the outperforming of the proposed algorithm against recent routing protocols in terms of packet delivery ratio and routing overhead.

The advantages of vehicular ad hoc networks (VANETs) have been acknowledged, particularly during the last decade. Furthermore, VANET-related issues have been addressed by different researchers. Forwarding information professionally in a VANET is considered a challenging task precisely at the intersections where forwarding the information turns out to be extremely problematic. To elucidate this problem, many researchers have established routing protocols. The improved greedy perimeter stateless routing protocol (IGPSR) has been suggested, in the direction of employing greedy-mode proceeding traditional transportation's streets as well as to employ intersection-method at the joints. In view of greedy mode, the selection of the following stage is as in GPSR. By contrast, in the mode at an intersection, we would expect the vehicle guidelines to govern the following stage. The recreated consequences expose the algorithm, which is anticipated to undeniably demonstrate its competency.
