A key component of intelligent transportation systems (ITS) is the provision of adequate network infrastructure to support vehicular communication. In this paper we present the results of an extensive measurement campaign evaluating the performance of IEEE 802.11 in different vehicular communication scenarios: vehicle-to-vehicle (V2V) and infrastructure- to-vehicle (I2V). We concentrate our evaluation on multi-hop communication in these two scenarios. We found that distance and line of sight communication are the two main factors affecting the network communication. The experimental results confirm also the feasibility of using ad hoc networks to extend the transmission range of the infrastructure and the connection time for cars in motion.
