The Latest Scientific Publications on IoT
The paper “BPNN-based flow classification and admission control for software defined IIoT“, published in IET Communications in July 2024, introduces an innovative Flow Admission Control (FAC) approach that aims to optimize service demands and maximize network utilization in software defined Industrial Internet of Things (IIoT). The proposed method addresses challenges such as access delays and service outages due to multiple connection requests. Researchers employed a back propagation neural network to classify incoming flows into various priorities based on real-time network status. Subsequently, the bandwidth and buffer size were estimated using a stochastic network calculus model. This dynamic approach adjusts FAC thresholds, unlike traditional static priority systems, ensuring real-time processing. Simulation results indicate that this novel FAC scheme significantly reduces transmission delays and enhances network utilization, outperforming existing methods. The study underscores the potential of machine learning and stochastic modeling in meeting the stringent demands of software-defined IIoT networks.
Low-Power Wide-Area Network (LPWAN) technologies, such as LoRa, are increasingly being adopted in agriculture due to their extensive range and power efficiency. However, the energy consumption of LoRa wireless sensor networks is significantly influenced by transmission parameters like carrier frequency, bandwidth, transmit power, spreading factor, and coding rate. Incorrect parameter selection can drastically reduce battery life, necessitating frequent replacements—a costly and inconvenient scenario for field deployments. A recent study “Machine learning deployment for energy monitoring of Internet of Things nodes in smart agriculture“, published in International Journal of Communication Systems in Jun 2024, introduces a machine learning-based web application designed to monitor the energy consumption of end nodes in LoRa wireless sensor networks. The research tested 12 regression models, including Linear, Random Forest, K-Nearest Neighbours, Decision Tree, Support Vector, Lasso, Ridge, AdaBoost, Gradient Boost, XGBoost, CatBoost, and LightGBM models. The LightGBM model emerged as the most accurate in predicting the energy consumption of IoT nodes and was thus chosen for the web application. This innovative application can be integrated into programmable LoRaWAN gateways, providing an efficient tool for monitoring and optimizing the energy consumption of IoT end nodes in the agricultural sector. This advancement promises to enhance the longevity and reliability of field-deployed devices, reducing maintenance costs and improving operational efficiency.
