Ensuring the privacy of organizations and individuals is a crucial issue in IoT networks, where sensitive data is transmitted and various types of attacks are prevalent. The importance of Intrusion Detection Systems (IDS) in detecting attacks and infiltration attempts on IoT networks is increasing daily. In this way, it will contribute to the resistance against attackers and the spread of this modern technology. In this study, Prediction Tree Traffic Analyzer (PT-TAnalyzer), an IDS system capable of detecting and classifying attacks on IoT networks, is proposed. PT-TAnalyzer features an ensemble model structure, where weighting is determined by the validation scores of machine learning models, and a prediction tree comprising eight ensemble models trained on the CIC-IoT-2023 dataset. This proposed model detects 34 attack types (including 33 malicious and one benign) with high success rates, due to its unique attack-detection approach, and does so efficiently and cost-effectively. Unlike traditional studies, it achieves this by using eight trained models rather than classifying all attacks with a single model and a single prediction structure within the tree architecture. In the tests performed, PT-TAnalyzer achieved 99.76 % accuracy in the binary classification experiment (Benign vs. Malicious) and 98.70 % accuracy in the 34-class experiment, yielding a similar F1 Score. The test time per sample is less than 0.1 ms. Compared with previous frameworks using the same dataset, PT-TAnalyzer shows a 2 % improvement in overall accuracy and a lower processing time. In practice, the proposed model can be deployed on IoT gateways or edge devices to provide real-time, low-cost, and scalable intrusion detection capabilities.

Furthermore, sustainability and the reduction of the carbon footprint are currently a priority due to industrial and governmental initiatives and requirements, such as Green IoT or the Sustainable Development Goals. The efforts in sustainability are aimed not only at achieving energy-efficient applications, but carbon-aware ones, aligning carbon footprint reduction with high QoS and low economic cost.

An aging-aware mechanism is proposed to deal with the service fairness and responsiveness by prioritizing the parcels based on their waiting time, and ultimately mitigating their backlog within the service field.
