Inter-network interactions in IoT, seminar by Laura Feeney, SICS and Uppsala University

Inter-network interactions in IoT: Protocols, network architecture, business models, and regulation.


IoT applications are expected to become ubiquitous in everyday life. This means that there will be many independently deployed networks operating in the same location.

Because these networks operate in unlicensed spectrum and are based on a wide range of enabling technologies, there is no natural basis for common administrative control between networks.  Increasingly crowded spectrum and inter-network interactions therefore pose a significant challenge to successful deployment, particularly in urban and residential environments.

Cross-technology interference (e.g. among IEEE 802.11, IEEE 802.15.4 and Bluetooth) is known to have a significant impact on low power networks and can severely limit the number of channels available to these devices.  This discussion therefore focuses on interactions between networks that use the same radio technology and operate on the same channel

I present some preliminary results that examine interactions between co-located IEEE 802.15.4 networks.  The results show complex link layer interactions, as well as significant impact on device energy consumption.  I conclude that there is a need for re-consideration of protocol performance. I also discuss the implications of these issues for IoT protocols and architectures, as well as for standardization, business models and regulation.

This is joint work with Viktoria Fodor at KTH.  Michael Frey at Humboldt University also contributed to the project during his study-visit at SICS.
