Performance Evaluation of IoT LoRa Networks on Mars Through ns-3 Simulations

2024-12-27

AI Summary

This study presents the first systematic feasibility assessment of LoRaWAN for terrestrial communication on Mars, specifically addressing the coupled effects of low atmospheric pressure and dust storms on radio signal propagation. A customized ns-3-based simulation platform is developed, integrating Mars-specific atmospheric parameters, free-space path loss (FSPL) modeling, and a dynamic dust-storm-induced channel attenuation model. Results demonstrate that commercial LoRaWAN devices support reliable short-range communication (<5 km) under nominal Martian conditions; however, intense dust storms severely degrade link performance, reducing the maximum reliable communication distance by approximately 40% compared to Earth—confirming dust storms as the primary limiting factor for long-range deployment. This work bridges a critical gap in deep-space IoT communication modeling and provides quantitative performance benchmarks and technical boundary constraints essential for designing future in-situ Martian IoT architectures.

Abstract

In recent years, there has been a significant surge of interest in Mars exploration, driven by the planet's potential for human settlement and its proximity to Earth. In this paper, we explore the performance of the LoRaWAN technology on Mars, to study whether commercial off-the-shelf IoT products, designed and developed on Earth, can be deployed on the Martian surface. We use the ns-3 simulator to model various environmental conditions, primarily focusing on the Free Space Path Loss (FSPL) and the impact of Martian dust storms. Simulation results are given with respect to Earth, as a function of the distance, packet size, offered traffic, and the impact of Mars' atmospheric perturbations. We show that LoRaWAN can be a viable communication solution on Mars, although the performance is heavily affected by the extreme Martian environment over long distances.
