Abstract

For an energy-efficient adaptive data rate (ADR) algorithm in a long-range wide-area network (LoRaWAN) system, an asymptotic analysis on the spreading factor (SF) by the ADR-MIN algorithm considering a probabilistic packet collision is presented. In addition, we propose a new ADR truncated MIN algorithm that selectively exploits signal-to-interference noise ratio (SINR) values for the accurate SINR estimation. From computer simulations, the proposed ADR design was observed to have a SF configuration near the asymptotic estimate and to be more energy efficient compared to existing ADR algorithms.

节能LoRaWAN系统的改进ADR算法分析与设计

针对远程广域网（LoRaWAN）系统中节能的自适应数据速率（ADR）算法，给出了考虑概率分组碰撞的ADR- min算法的扩展因子（SF）渐近分析。此外，我们提出了一种新的ADR截断MIN算法，该算法选择性地利用信噪比（SINR）值来准确估计SINR。从计算机模拟中可以观察到，与现有的ADR算法相比，所提出的ADR设计在渐近估计附近具有SF配置，并且更节能。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
