Abstract:
A radio communication system is a complex dynamic phenomenon where transmitter and receiver antennas are constantly constrained by the physical environment in which they are deployed. In the real world, radio transmissions are subject to propagation effects which deeply affect the received signals because of geographic and environmental characteristics (foliage and vegetation, buildings, mountains and hills, etc.). Multi-Agent Geo-Simulation aims to simulate such phenomena involving a large number of autonomous situated actors (implemented as software agents) evolving and interacting within a representation of the physical environment. Using a geo-computation approach, we propose to use an Informed Virtual Geographic Environment (IVGE) along with MAGS paradigm. In addition, we propose a multi-agent prototype to analyze the attenuation effect due to the radio signal’s traversal between antennas (simulated as software agents) through terrain shape, vegetation area, and buildings using a 3D line-of-sight computation technique.
