Abstract
Link failure cause packet loss, increased delays, disconnection from the network or even the shutdown of the inter-vehicle communication system vehicle-to-vehicle. Routing protocols suffer from this situation due to the lack of fault tolerance mechanisms that are intended to make the vehicular ad hoc network capable of remaining functional over time with low response time and/or high throughput; despite failures. Through this paper, we propose a version of the Greedy Perimeter Stateless Routing (GPSR) protocol that is tolerant to link failures based on the prediction of the future position of each vehicle (position prediction-GPSR) and a minimum threshold of the vehicle coverage area (position predictive with threshold-GPSR) to elect the next hops. Simulation results show that the proposed approach offers good performance.
