Summary:Vehicular Ad-hoc Networks (VANET) is a vital technology for futuristic Intelligent Transport System (ITS). VANET is a sub level of Mobile Ad-hoc Network (MANET), which establishes connectivity among vehicles with wireless medium. Once the vehicles communicate directly with each other, then there arises a new era for vehicle and road safety applications. At the same time creates new challenges by mobility of vehicles with dynamic network environment. As ITS keeps developing, there is a necessity to enhance safety application with high packet delivery rates, and reduce packet latency. This paper proposes a hybrid routing protocol called Directional-Cache Agent based Location Aided Routing (D-CALAR). D-CALAR is a combination of position based and Geocast routing. A mathematical representation for D-CALAR protocol is derived to analyze its performance. Simulation has been carried out using NS-2.33 and VanetMobiSim. From the simulated result, it seems that D-CALAR routing protocol outperformed DD-LAR, PSCAR and ID-LAR in terms of Packet Delivery Ratio, Re-transmission Ratio, Average Delay and Hop Count.
