Modeling-Simulation of an Underground Wireless Communication Channel

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 216)

Abstract

Wireless communication inside mines and tunnels is very different from that in terrestrial environment because of the strong attenuation of signals. Here, we have tried to develop an empirical model for the underground wireless communication channel based on experimental data. The model developed is based on the available outdoor and indoor propagation models such as Okumara-Hata, COST231, ITU indoor propagation models. Modeling is done by super position method. Choosing the most appropriate model among the available ones for the given data and performing regression methods to do curve curve fitting. Correction factors are then added based on two parameters, namely, diffraction and low frequency interference losses. Losses due to penetration and multi path loss are assumed to be constants. MAT LAB is used for curve fitting.
