An Analytical Packet Error Rate Model for WAVE Receivers

Vehicular Ad-Hoc Networks (VANETs) have been extensively studied in the last years. Despite the availability of IEEE 802.11p transceivers, most of the literature presents simulation results, rather than real-world measurements. This is mainly due to the capability of simulations to facilitate interpretations of results; in fact any event can be decomposed into basic sub-events and the related causes analyzed in depth. However, this requires realistic settings of simulations to lead to consistent conclusions. Nowadays, most of the network simulators neglect the probabilistic nature of the decoding process at the receiver and this may have significant impact on the results. This paper is meant to fill this gap by proposing an analytical Packet Error Rate (PER) model for 802.11preceivers, particularly suitable for the implementation within packet-level simulators. It is completely parameterized as a stochastic function of line-rate, Signal to Noise ratio (SNR) and packet length, and it is consistent with experimental measurements.
