Spatial Diversity for IEEE 802.11p Post-Crash Message Dissemination in a Highway Environment

Free registration required

Executive Summary

In this paper, the authors evaluate the performance of broadcast safety applications in a Vehicular-To-Vehicular (V2V) communication scenario using a BER-based reception model from a detailed IEEE 802.11p physical layer simulator for a more accurate interpretation of the vehicular communication system, instead of the prebuilt SNR threshold model available in a typical network simulators. Their main contribution is the spatial diversity analysis provided using MIMOSTBC, that is specific to modulation types, vehicular speeds and range of SNR values.
