Consumer IoT device deployment optimisation through deep learning: a CNN-LSTM solution for traffic classification and service identification

Abstract

The internet of things (IoT) has revolutionised our world, connecting devices and creating a more intelligent and interconnected environment. However, managing and utilising the vast amount of data generated by these devices is a major challenge. To address this, we propose a novel approach in this article that combines convolutional neural networks (CNNs) with long short-term memory (LSTM) networks to optimise IoT device deployment. The process involves data preparation, defining and training a deep learning model on preprocessed data, and using the trained model to categorise network traffic from IoT devices. Our experimental results demonstrate exceptional accuracy of over 99.99%. We evaluate the model's performance using classification metrics and compare it with commonly used traffic predictive models. Additionally, our approach provides valuable insights into the services offered by IoT devices by analysing their traffic patterns, distinguishing between monitoring, home automation, and appliance usage.
