The Vehicular Ad-Hoc Network, or VANET, is a technology that uses moves cars as nodes in a network to create a mobile network. VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 metres of each other to connect and, in turn, create a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. Working with GPSR routing protocol main aim is to increase the performance and the efficiency of the GPSR as well as E-GPSR routing protocol. In this paper, we also give out a mathematical model to evaluate the performance of our proposal. Basing on the model, we use ns to simulate the highway condition. Form the result, we find that our proposal is better that GPSR at aspect of time delay. But in the packet delivery ratio, it doesn't bring us a remarkable improvement. The proposed methodology considers the border node and angle of orientation of the neighboring nodes. Based on this the D-GPSR outperforms the GPSR and E-GPSR routing protocol in terms of throughput, average end-to-end delay, packet delivery ratio and network load. D-GPSR is methodology and algorithm is studied in detailed.
