A Lightweight Radio Propagation Model for Vehicular Communication in Road Tunnels

摘要: Radio propagation models (RPMs) are generally employed in Vehicular Ad Hoc Networks (VANETs) to predict path loss multiple operating environments (e.g. modern road infrastructure such as flyovers, underpasses and tunnels). For example, different RPMs have been developed behaviour tunnels. However, most existing for tunnels computationally complex based on field measurements frequency band not suitable VANET deployment. Furthermore, tunnel applications, consequences of moving radio obstacles, large buses delivery trucks, considered RPMs. This paper proposes a inexpensive RPM with minimal set parameters an acceptable range The proposed utilizes geometric properties the tunnel, height width along distance between sender receiver, loss. also considers additional attenuation caused by obstacles tunnels, while requiring negligible overhead terms computational complexity. To demonstrate utility our RPM, we conduct comparative summary evaluate its performance. Specifically, extensive data gathering campaign is carried out order RPM. use 5 GHz band, which vehicular communication. results that close match exists predicted values measured In particular, average accuracy 94% found R2 = 0.86.
