What is it about?
This work presents a new long-range IoT communication system for LoRa, to overcome limitations of the existing LoRaWAN network architecture, which suffers from centralization and wireless interference. To achieve this, we replace the media access scheme and introduce information-centric networking (ICN). Our solution LoRa-ICN provides robust radio transmission, low power consumption on battery driven devices, and enables data sharing for LoRa-based edge networks.

Why is it important?
LoRa based communication incurs significant delays. Connecting these nodes to a fast information-centric network, or the Internet, is challenging. Routing entries expire, and retransmission timers operate at a different (fast) time scale, which results in brittleness polling or systematic data loss. This introduces inefficiency on both, the battery operated IoT device, and Internet nodes. LoRa-ICN provides solutions to these problems.
Perspectives
Developing the evaluation environment for this work took lots of engineering effort and the availability of open source code (RIOT, CCN-lite, openDSME) was the enabler for our implementation. Writing this article was a pleasure as it has co-authors that retrospect to long standing experience in the field of ICN/IoT/networking research. This article also opened many future research directs and the reproducible evaluation environment acts as a direct starting point.
