【Abstract】The ongoing growth of the Internet of Things (IoT) offers great opportunities to improve the way we understand and interact with the physical world. However, existing approaches face a number of challenges from providing scalable and reliable services to users to addressing the need for security and privacy. We believe decentralised architectures offer a valuable alternative to centralised approaches. However, increased performance and communication requirements render existing decentralised technologies unsuitable for use with the constrained edge- and end-devices popular in the IoT. In this paper we address these limitations. First by extending DSF-IoT with a novel mechanism for delegation to enable transparent interactions with and between IoT services on constrained and unconstrained end-devices without the trust and privacy boundaries of existing approaches. Second, delegation is demonstrated through the creation of what we believe to be the first real-world heterogeneous decentralised IoT network spanning WSAN connected microcontrollers, Arm-based single board computers, and unconstrained x64 devices. Third, we qualify DSF-IoT for use on constrained edge-devices through the development of a constrained gateway prototype and test-bench for measuring the performance of IoT brokers under varying operating conditions. This demonstrates that DSF-IoT offers equivalent (or improved) performance to popular CoAP and MQTT brokers on constrained edge-devices while providing historical data storage and access as well as end-toend trust and privacy. Finally we perform a functional comparison of DSF-IoT against existing protocols and research to highlight the advantages of our approach and the suitability of DSFIoTs and delegation for use with constrained edge- and end-devices to enable the creation of a truly heterogeneous future decentralised Internet of Things.
