Using Blockchain Technology to Build Trust in Sharing LoRaWAN IoT

With1 the rapid growth of the internet of things (IoT) market and requirement, low power wide area (LPWA) technologies have become popular. In various LPWA technologies, Narrow Band IoT (NB-IoT) and long range (LoRa) are two main leading competitive technologies. Comparing to NB-IoT network that mainly built and managed by mobile network operators, LoRa wide-area network (LoRaWAN) is mainly operated by private companies or organizations, which will bring the trust issues between application customers and network operations. In this paper, we proposed a blockchain technology based solution to build an open, trusted, decentralized and tamper-proof system for LoRaWAN. To the best of our knowledge, this is the first work that integrating blockchain technology and LoRaWAN IoT technology.
