Modeling of Correlated Blockage in Highway Vehicular Networks

This paper presents a novel spatially consistent approach for addressing blockage and line-of-sight (LOS) paths in highway vehicular networks. We use stochastic geometry to model transmitters, obstacles, and receivers located in three lines, respectively. Then, their geometric interactions characterize the existence of LOS paths. Specifically, the proposed approach focuses on the role of obstacles in blocking one or more LOS paths, which has been overlooked in most statistical models for blockage. Under the proposed framework, we derive the probability that a typical vehicle is in LOS with respect to transmitters. The proposed framework and LOS analysis are important to the LOS-critical applications such as positioning or mmWave communications in vehicular networks.
