Ns-3 Simulation Model for Underground Networks

Introduction

Objectives

The goal of this dissertation is to develop a new simulation model for ns-3 that allows simulation of wireless underground networks for different frequencies, types of soils and depths of the nodes. The ns-3 model has to be able to simulate communications between buried nodes and between buried nodes and aboveground nodes. To achieve this goal the work was divided into some specific objectives:

  • Study the major properties characterizing the soil and models;
  • Study some experiments and the existing radio propagation models for underground networks;
  • Study the ns-3 simulation environment, in particular the methodology that shall be used to implement and add new models to the simulator;
  • Implement the propagation models in ns-3;
  • Simulate the same experimental scenarios found in literature and compare the obtained results with the documented ones;
  • Conclude about the accuracy of the implemented wireless underground simulation environment.
