Abstract

LoRaWANs play a critical role in various applications such as smart farming, industrial IoT, and smart cities. The strategic placement of gateways significantly influences network performance optimization. This study presents a comprehensive analysis of the tradeoffs between system costs and bitrate maximization for selecting optimal gateway locations in LoRaWANs. To address this challenge, a rigorous mathematical model is formulated to incorporate essential factors and constraints related to gateway selection. Furthermore, we propose an innovative metaheuristic algorithm known as the M-VaNSAS algorithm, which effectively explores the solution space and identifies favorable gateway locations. The Pareto front and TOPSIS methods are employed to evaluate and rank the generated solutions, providing a robust assessment framework. Our research findings highlight the suitability of a network model comprising 144 gateways tailored for the Ubon Ratchathani province. Among the evaluated algorithms, the M-VaNSAS method demonstrates exceptional efficiency in gateway location selection, outperforming the PSO, DE, and GA methods.

远距离广域网中网关位置选择的多目标优化：系统成本与比特率最大化之间的权衡分析

LoRaWAN 在智能农业、工业物联网和智能城市等各种应用中发挥着至关重要的作用。网关的战略布局对网络性能优化有重大影响。本研究全面分析了系统成本与比特率最大化之间的权衡，以选择 LoRaWAN 中的最佳网关位置。为应对这一挑战，我们制定了一个严格的数学模型，将与网关选择相关的重要因素和约束条件纳入其中。此外，我们还提出了一种被称为 M-VaNSAS 算法的创新元启发式算法，该算法可有效探索解决方案空间并确定有利的网关位置。我们采用帕累托前沿法和 TOPSIS 法对生成的解决方案进行评估和排序，从而提供了一个稳健的评估框架。我们的研究结果突出表明，由 144 个网关组成的网络模型非常适合乌汶叻差他尼府。在所评估的算法中，M-VaNSAS 方法在网关位置选择方面表现出卓越的效率，优于 PSO、DE 和 GA 方法。
