Abstract

Most Internet of Things (IoT) communication technologies rely on terrestrial network infrastructure. When such infrastructure is not available or does not provide sufficient coverage, satellite communication offers an alternative IoT connectivity solution. Satellite-enabled IoT devices are typically powered by a limited energy source. However, as of this writing, and to our best knowledge, the energy performance of satellite IoT technology has not been investigated. In this paper, we model and evaluate the energy performance of Iridium satellite technology for IoT devices. Our work is based on real hardware measurements. We provide average current consumption, device lifetime, and energy cost of data delivery results as a function of different parameters. Results show, among others, that an Iridium-enabled IoT device, running on a 2400 mAh battery and sending a 100-byte message every 100 min, may achieve a lifetime of 0.95 years. However, Iridium device energy performance decreases significantly with message rate.

摘要

大多数物联网（IoT）通信技术依赖于地面网络基础设施。当这种基础设施不可用或覆盖范围不足时，卫星通信提供了一种替代的物联网连接解决方案。支持卫星的物联网设备通常由有限的能源供电。然而，截至撰写本文时，据我们所知，卫星物联网技术的能源性能尚未得到研究。在本文中，我们对用于物联网设备的铱星卫星技术的能源性能进行建模和评估。我们的工作基于实际硬件测量。我们给出了作为不同参数函数的平均电流消耗、设备寿命和数据传输的能源成本结果。结果表明，除其他外，一个运行在2400毫安电池上、每100分钟发送一条100字节消息的铱星物联网设备，其寿命可能达到0.95年。然而，铱星设备的能源性能会随着消息速率的增加而显著下降。
