Long-range communication technologies are increasingly used due to the internet of things (IoT) deployments and their ability to perform for long-range and low power while providing a multiyear battery life. In this paper, we study security management, counter management, message acknowledgment, and vulnerabilities of LoRaWAN. We propose a jamming attack to interfere or disrupt the LoRa network by using software-defined radio-based universal software radio peripheral (USRP), GNU radio, and LoRa devices. Our analysis shows that LoRa transmission gets affected because of the coexistence of other LoRa transmission. While the impact of the interference and the effect of the imperfect orthogonality of spreading factor (SF) much depend upon the distance between LoRa communicating devices and the interference source. © 2019 IEEE.
