Title
Machine Learning Framework for Sensing and Modeling Interference in IoT Frequency Bands
Abstract
Spectrum scarcity has surfaced as a prominent concern in wireless radio communications with the emergence of new technologies over the past few years. As a result, there is a growing need for better understanding of the spectrum occupancy with newly emerging access technologies supporting the Internet of Things. In this article, we present a framework to capture and model the traffic behavior of short-time spectrum occupancy for Internet-of-Things (IoT) applications in the shared bands to determine the existing interference. The proposed capturing method utilizes a software-defined radio to monitor the short bursts of IoT transmissions by capturing the time-series data which is converted to power spectral density to extract the observed occupancy. Furthermore, we propose the use of an unsupervised machine learning technique to enhance conventionally implemented energy detection methods. Our experimental results show that the temporal and frequency behavior of the spectrum can be well captured using the combination of two models, namely, semi-Markov chains and a Poisson-distribution arrival rate. We conduct an extensive measurement campaign in different urban environments and incorporate the spatial effect on the IoT shared spectrum.
