Background/Objectives: Routing protocols play an important role in the performances of Vehicular Ad Hoc networks (VANET). Routing protocols procedures are controlled with a set of parameters from being dragged to undesired situations such as flooding the network with unnecessary overhead. These parameters have a direct impact on the efficiency of a routing protocol and the overall network performances. The impacts of these parameters on the network performances are less considered in the literature. Methods: This paper proposed the Taguchi delta analysis to measure the impact of Greedy Perimeter Stateless Routing (GPSR) protocols parameters on the performances of VANET. Then, the obtained results are investigated with iterative method to validate the Taguchi observations. Further, an offline optimization of the GPSR parameters is evaluated by performing Taguchi SNR method for fine-tuning the GPSR routing parameters. Application/ Improvements: GPSR with Taguchi tuned is compared with GPSR configuration in a realistic VANET scenario. The obtained results showed that, GPSR with Taguchi configuration outperformed the GPSR in terms of delay and PDR on the simulated scenarios.
