SIMPLARCOM: simulador para planejamento de redes de comunicação sem fio utilizando realidade virtual e modelos de propagação

Abstract

This simulator is formed by the junction of Virtual Reality techniques with propagation models, developed through the studies of radio enlace, describing the loss that the transmitted signal suffers along the way in the environment. The Simulator has two modules. The first allows the creation of virtual environment with the placement, on a ground, buildings, trees, cars, antennas and other primitives that allow the construction of a customizable three-dimensional environment. The second module allows the configuration of the parameters related to antenna signal propagation as power, frequency, gain, etc., and also selects the propagation model for the simulation execution. Within this second module, there is a submodule responsible for coverage area planning study composed by antennas, in other words, this submodule simulates the distance that each antenna in the scenario can reach and generates its coverage area. To demonstrate the Simulator efficiency was created two virtual environments for testing. A scenario representing an urban environment where employed a classic propagation model, Okumura-Hata to small and medium-sized cities, and a wooded three-dimensional environment using a specific model for propagation simulation of densely wooded regions, developed at the Federal University of Pará called Lyra- Castro-UFPA.
