| Summary: | Due to the unpredictable trajectory of its moving nodes, a VANET is a demanding communication environment. For such dynamic communication infrastructures, when certain requirements neet to be coped, the performance is a critical parameter. In this paper, we evaluate the VANET performance when an anonymous reporting service is deployed. In order to pay off the overhead generated by the anonymity service (based on the Crowds mechanism), we tune the layer-two address resolution protocol (ARP) so that it can be performed at the routing level. The tests are done with different VANET routing protocols and vehicle densities by means of simulations of a realistic scenario where the parameters of the anonymity service are also modified to determine their impact on the overall performance of the vehicular network. We found that, despite the more demanding environment generated by the deployment of the anonymity service, the VANET has a good performance in terms of packet losses, delay, and neighboring behavior, thanks to the implementation of a more efficient layer-two address resolution mechanism. |
