In this work, we evaluate the performance of three routing protocols epidemic, spray and wait and maxprop in Vehicular Delay Tolerant Networks (VDTNs). We study the impact of vehicles density and ttl on the network performance. The simulations are conducted with the Opportunistic Network Environment (ONE) simulator. The performance is analyzed using delivery probability, overhead ratio, average latencyand average number of hops metrics. The simulation resultsshow that the increase of node density improves the networkperformance. In dense network scenario, the performance ofepidemic and maxprop routing protocols is better because thenumber of opportunistic contacts between nodes increases. Forsprayandwait the performance is not improved since it uses amaximum of two hops to deliver bundles. Hence, in densenetworks, a bundle may have a significant delay because itcan only be delivered when a relay or source node have andopportunistic contact with the destination. The increase of ttlfrom 30 to 120 min does not improve the performance of threerouting protocols in both scenarios.
