不同参数设置下LoRaWAN性能的深入研究
A Thorough Study of LoRaWAN Performance Under Different Parameter Settings
摘要：
LoRaWAN是一种新兴的低功耗广域网（LPWAN）技术，由于其灵活性和易于部署，该技术正在获得发展势头。与其他LPWAN解决方案相反，LoRaWAN确实允许配置影响不同网络性能指标的多个网络参数，例如能效，公平性和容量，原则上可以使网络行为适应应用场景的特定要求。不幸的是，不同网络组件之间复杂且有时难以捉摸的相互作用使得很难预测某些参数设置的实际效果，因此如果不深入理解，灵活性可能会成为绊脚石。在本文中，我们揭示了这种复杂的相互作用，通过观察和解释不同的参数设置在一些说明性的情况下的效果。基于模拟的分析揭示了各种权衡，并强调了LoRaWAN标准设计中的一些低效率。此外，我们展示了如何通过明智地设置系统参数，可能与一些新的网络管理策略相结合，可以获得显着的性能增益。
英文摘要：
LoRaWAN is an emerging Low-Power Wide Area Network (LPWAN) technology, which is gaining momentum thanks to its flexibility and ease of deployment. Conversely to other LPWAN solutions, LoRaWAN indeed permits the configuration of several network parameters that affect different network performance indexes, such as energy efficiency, fairness, and capacity, in principle making it possible to adapt the network behavior to the specific requirements of the application scenario. Unfortunately, the complex and sometimes elusive interactions among the different network components make it rather difficult to predict the actual effect of a certain parameters setting, so that flexibility can turn into a stumbling block if not deeply understood. In this paper we shed light on such complex interactions, by observing and explaining the effect of different parameters settings in some illustrative scenarios. The simulation-based analysis reveals various trade-offs and highlights some inefficiencies in the design of the LoRaWAN standard. Furthermore, we show how significant performance gains can be obtained by wisely setting the system parameters, possibly in combination with some novel network management policies.
