Evaluation of Communication Distance of Broadcast Messages in a Vehicular Ad-Hoc Network Using IEEE 802.11p

Current research for vehicular communication is largely driven by the allocation of 75MHz spectrum in the 5.9GHz band for dedicate short range communications (DSRC) in North America. The IEEE 802.11p physical (PHY) layer and medium access control (MAC) layer that is currently under standardization aim at communication distances of up to 1000m. In this paper we evaluate the maximum communication distance of an IEEE 802.11p vehicular ad-hoc network including mobility effects and multi-path propagation. Furthermore the communication distance for different path loss exponents is evaluated.
