[Invited] LoRaCTP: a LoRa based Content Transfer Protocol for sustainable edge computing

Abstract

In this paper we present a flexible protocol based on LoRa technology that allows for the transfer of “content” to large distances with very low energy. LoRaCTP provides all the necessary mechanisms to make LoRa reliable, by introducing a lightweight connection set-up and ideally allowing the sending of an as-long-as necessary data message. We designed this protocol as a communication support for edge based IoT solutions given its stability, low power usage and the possibility to cover long distances. We present the evaluation of the protocol with various sizes of data content and various distances to show its performance and reliability.
