论文摘要
远程广泛区域网络（Lorawan）是一种开放的中型访问控制（MAC）层技术，该技术设计用于大量低功率网络设备的远程连通性。这项工作概述了Lorawan技术的关键方面，并提出了我们通过使用最先进的网络模拟器（NS-3）对不同网络设置中A类Lorawan设备进行广泛评估来实现的结果。首先，我们专注于单个设备及其移动性。我们在扩展的网络方案中进一步进行了评估，并随着设备和流量强度的变化。特别是，我们评估了数据包输送比（PDR），上行链路（UL）吞吐量以及在不同环境中已确认和未经证实的UL传输的子频段利用。我们的结果为将来的努力提供了新的见解，以优化具有低功率最终设备的不同大型物联网（IoT）应用程序的Lorawan性能。
Long Range Wide Area Networks (LoRaWAN) is an open medium access control (MAC) layer technology devised for the long range connectivity of massive number of low power network devices. This work gives an overview of the key aspects of LoRaWAN technology and presents results that we achieved via extensive evaluation of Class A LoRaWAN devices in different network settings using the state-of-the-art network simulator (NS-3). At first, we focus on a single device and its mobility. We further undertook evaluations in an extended network scenario with a changing number of devices and traffic intensity. In particular, we evaluate the packet delivery ratio (PDR), uplink (UL) throughput, and sub-band utilization for the confirmed and unconfirmed UL transmissions in different environments. Our results give new insights for future efforts to optimize the LoRaWAN performance for different large scale Internet of Things (IoT) applications with low power end devices.
