Source route implementation using intersection node on GPSR protocol to increase VANET's data transmission reliability

Vehicular Ad Hoc Network (VANET) is one of the networking technology that is advancing widely in several countries. VANET research focuses mainly on the routing efficiency. Routing protocol becomes the main emphasis because there is a demand on fast and reliable route determination, where a route must be determined from a certain source to destination as fast as possible with an optimal accuracy. Each of the routing protocol, namely Topology Based Protocol and Geographic Based Protocol have their own trade-off. Therefore, we require a combination of these two routing protocols to resolve each of their cons. This paper implements a source route protocol method called DSR protocol with the help of intersection node at GPSR protocol to increase the data transmission reliability on VANET. Intersection node is a static node that stands at every crossroad. The experiment result shows that the implementation of source route with the help of intersection node was able to increase the reliability of data transmission on VANET.
