A LoRaWAN-Based Network Architecture for LEO Satellite Internet of Things

摘要

Though short range communication technologies still support the major part of the Internet of Things (IoT) connections in the future, low power wide area networks (LPWAN) have shown great competitive power among other IoT connecting technologies. Moreover, to overcome the coverage limitation of terrestrial networks, IoT combining with satellite networks can provide services globally and seamlessly. Among satellites from different kinds of orbits, low earth orbit (LEO) satellite is a good candidate to provide IoT services due to its low propagation delay, small propagation loss and global coverage ability. In this paper, we present an LoRaWAN-based network architecture for LEO Satellite Internet of Things. Besides, we describe several significant processes for this IoT network.
