Abstract: In recent years, the innovation of Vehicular Ad-hoc Networks (VANET’s) communication has become more prominent and provides a wide variety of services for effective communication, permitting individuals to impart the road information with one another. Vehicular Ad-hoc Networks are exceptional sort of Mobile Ad-hoc Networks (MANET’s) in which nodes are profoundly motile, so the network topology changes very rapidly. Furthermore there is no limitation on the network size. All of these attributes have made VANET environment a challenge for developing routing protocols. For the better execution in networks, VANET requires a special support, which makes the network quick, secure and proficient. In order to frame the communication there are several routing protocols that provides optimal path for delivery of packets. In this paper, the Geo-cast routing protocols (GPRs) are applied on highways in view of on traffic environment. The two routing protocols i.e. Information Propagation Speed Analysis (IPSA) in Highway vehicular networks and Mobicast Routing (MR) for Highway Traffic Environment are examined. The path developments from the source node (vehicle) to the destination node based on different criteria are considered. The outcomes are dissected utilizing MATLAB simulation.
