Characterization and performance evaluation of 802.11p NICs

The automotive industry is scrambling to equip high- and middle-segment vehicles with communication capabilities that will enable the commercialization of connected vehicles in the near future. Although both IEEE and 3GPP are devel- oping new solutions, it is likely that IEEE 802.11p will be the protocol of choice. In this paper, we develop an open-source testing framework for IEEE 802.11p cards and character- ize the performance of Unex DHXA-222 cards in terms of throughput and packet loss, especially when different traffic classes, hence access categories, are selected.
