Intelligent Transportation System (ITS) uses Inter-Vehicle Communications (IVC) to perform safety messaging between vehicles. Dedicated Short Range Communication (DSRC) standard was drafted as an enhanced protocol for Vehicular Ad hoc NETwork (VANET) communications. DSRC has promising potential to increase vehicle safety as well as to enhance driving experience.

The vision of ITS is to equip both roads and vehicles with DRSC transceivers called Road Side Units (RSU) and On-Board Unit (OBU) respectively. However, DSRC is still in draft version, so markets don‟t have standard DRSC transceivers. Moreover, it will be very expensive, especially that we need a large number of nodes to reflect a real world scenario on inter-vehicle communication.

We have built a generic test bed that can be used to evaluate and analyze the performance of IEEE802.11 based protocols including DSRC. The test bed used low-cost WiFi nodes to emulate multiple vehicles contending for the medium. This test bed allowed us to evaluate jitter time and channel throughput for different protocols. The results will be presented in the poster.
