Abstract:
Long range radio communication is preferred in many IoT deployments as it avoids the complexity of multihop wireless networks. LoRa is a popular, energy-efficient wireless modulation but its networking substrate LoRaWAN introduces severe limitations to its users for use cases such as industrial automation. DSME-LoRa, a system design of LoRa with IEEE 802.15.4 Deterministic Synchronous Multichannel Extension (DSME), is a good candidate to overcome these limitations. DSME-LoRa offers the advantage of
seamless client-to-client communication beyond the pure gateway-centric transmission of LoRaWAN. In my talk I evaluate its feasibility via a full-stack implementation on RIOT and quantify its scalability in massive communication scenarios using large scale network simulations.
