Beartooth Relay Protocol: Supporting Real-Time Application Streams with Dynamically Allocated Data Reservations over LoRa

Convenient solutions that cater to different types of applications always gather more users. LoRa, one of the solutions in the IoT space is quite flexible at the physical layer, but link layer LoRa protocols lack similar flexibility. As a result, their performance remains suitable for the exchange of short messages in sensor networks, but does not extend to real-time and streaming IoT applications. Beartooth Relay Protocol (BRP) aims to address these limitations with a configurable link layer solution without compromising performance to sustain real-time flows over LoRa. We demonstrate that BRP expands the performance envelope of LoRa and makes it a suitable PHY technology for a wide range of IoT applications.
