Reliability Analysis of Safety Intervehicle Communications in a Highway Environment

Abstract

Abstract-Vehicular network can improve traffic safety by exchange of safety-related messages between the vehicles within the the neighborhood of each other. However, many research related to vehicular network depends heavily on system-level simulation. In this paper, we use tools from stochastic geometry to analyze the reliability of the transmission of periodic message in a highway scenario. A Poission point process (PPP) basedbased network and slotted-aloha MAC scheme is assumed. Three-slope pass loss and rayleigh-lognormal fading are taken into consideration. Coverage probability and packet reception rate (PRR) are adopt as the reliability metrics. We then derive the closed form expressions of coverage probability and PRR. Finally, the accuracy of the analysis is validated via simulation.
