Neighborhood Evaluation of Vehicular Ad-Hoc Network Using IEEE 802.11p

Overview 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. To achieve longer distances, multi-hop communication is needed. The number of neighbor vehicles is an important input parameter for algorithms that choose the optimal next transmitter of a multi-hop chain. This paper evaluates the number of potential communication partners in communication range of an IEEE 802.11p vehicular ad-hoc network including mobility effects and multi-path propagation. In addition the available communication duration is evaluated.
