Special Issue Information

Dear Colleagues,

The aim of this special issue is to explore the potential of Tiny Machine Learning techniques in enhancing the capabilities of sensors in the context of the Internet of Things (IoT).

With the rapid growth of IoT applications, sensors play a crucial role in collecting and transmitting data. However, the limited resources of sensors often pose challenges in terms of data processing and analysis. Tiny Machine Learning offers a promising approach to address these challenges by providing lightweight machine learning algorithms and methods that can be deployed directly on sensors.

This special issue aims to bring together researchers and practitioners to discuss and showcase the latest advancements and applications of Tiny Machine Learning in empowering sensors within the IoT ecosystem. We invite original research articles, reviews, and perspectives on the following topics:

  • Tiny Machine Learning algorithms for sensor data processing and analysis.
  • Hardware and software platforms for implementing Tiny Machine Learning on sensors.
  • Applications of Tiny Machine Learning in various IoT domains, including healthcare, environmental monitoring, smart cities, and industrial automation.
  • Energy-efficient and resource-constrained machine learning models for sensors.
  • Performance evaluation and benchmarking of Tiny Machine Learning techniques on sensor devices.
  • Security and privacy considerations in deploying Tiny Machine Learning on sensors.

This study presents an advanced framework integrating LLAMA_V2, a large language model, into Open Radio Access Network (O-RAN) systems. The focus is on efficient network slicing for various services. Sensors in IoT devices generate continuous data streams, enabling resource allocation through O-RAN’s dynamic slicing and LLAMA_V2’s optimization. LLAMA_V2 was selected for its superior ability to capture complex network dynamics, surpassing traditional AI/ML models. The proposed method combines sophisticated mathematical models with optimization and interfacing techniques to address challenges in resource allocation and slicing. LLAMA_V2 enhances decision making by offering explanations for policy decisions within the O-RAN framework and forecasting future network conditions using a lightweight LSTM model. It outperforms baseline models in key metrics such as latency reduction, throughput improvement, and packet loss mitigation, making it a significant solution for 5G network applications in advanced industries.

The sensors used in the Internet of Medical Things (IoMT) network run on batteries and need to be replaced, replenished or should use energy harvesting for continuous power needs. Additionally, there are mechanisms for better utilization of battery power for network longevity. IoMT networks pose a unique challenge with respect to sensor power replenishment as the sensors could be embedded inside the subject. A possible solution could be to reduce the amount of sensor data transmission and recreate the signal at the receiving end. This article builds upon previous physiological monitoring studies by applying new decision tree-based regression models to calculate the accuracy of reproducing data from two sets of physiological signals transmitted over cellular networks. These regression analyses are then executed over three different iteration varieties to assess the effect that the number of decision trees has on the efficiency of the regression model in question. The results indicate much lower errors as compared to other approaches indicating significant saving on the battery power and improvement in network longevity. Full article
