High-emitter identification for heavy-duty vehicles by temporal optimization LSTMand an adaptive dynamic threshold Research Article

Zhenyi XU, Renjun WANG, Yang CAO, Yu KANG

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 11,   Pages 1633-1646 doi: 10.1631/FITEE.2300005

Abstract: Heavy-duty diesel vehicles are important sources of urban nitrogen oxides (NO) in actual applications for environmental compliance, emitting more than 80% of NO and more than 90% of particulate matter (PM) in total vehicle emissions. The detection and control of heavy-duty diesel emissions are critical for protecting public health. Currently, vehicles on the road must be regularly tested, every six months or once a year, to filter out high-emission mobile sources at vehicle inspection stations. However, it is difficult to effectively screen high-emission vehicles in time with a long interval between annual inspections, and the fixed threshold cannot adapt to the dynamic changes of vehicle driving conditions. An is installed inside the vehicle and can record the vehicle’s emission data in real time. In this paper, we propose a long short-term memory (LSTM) and adaptive approach to identify heavy-duty high-emitters by using OBD data, which can continuously track and record the emission status in real time. First, a LSTM emission prediction model is established to solve the attention bias discrepancy problem on time steps that is caused by the large number of OBD data streams in practice. Then, the concentration prediction error sequence is detected and distinguished from the anomalous emission contexts using flexible criteria, calculated by an adaptive with changing driving conditions. Finally, a similarity metric strategy for the time series is introduced to correct some pseudo anomalous results. Experiments on three real OBD time-series emission datasets demonstrate that our method can achieve high accuracy anomalous emission identification.

Privacy and security federated reference architecture for Internet of Things Position Paper

Musab KAMAL, Imran RASHID, Waseem IQBAL, Muhammad Haroon SIDDIQUI, Sohaib KHAN, Ijaz AHMAD,waseem.iqbal@mcs.edu.pk

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 4,   Pages 481-508 doi: 10.1631/FITEE.2200368

Abstract: Physical objects are getting connected to the Internet at an exceptional rate, making the idea of the a reality. The IoT ecosystem is evident everywhere in the form of smart homes, health care systems, wearables, connected vehicles, and industries. This has given rise to risks associated with the privacy and security of systems. Security issues and cyber attacks on IoT devices may potentially hinder the growth of IoT products due to deficiencies in the architecture. To counter these issues, we need to implement privacy and security right from the building blocks of IoT. The IoT architecture has evolved over the years, improving the stack of architecture with new solutions such as scalability, management, interoperability, and extensibility. This emphasizes the need to standardize and organize the IoT reference architecture in federation with privacy and security concerns. In this study, we examine and analyze 12 existing IoT reference architectures to identify their shortcomings on the basis of the requirements addressed in the standards. We propose an architecture, the privacy-federated IoT security reference architecture (PF-IoT-SRA), which interprets all the involved privacy metrics and counters major threats and attacks in the IoT communication environment. It is a step toward the standardization of the domain architecture. We effectively validate our proposed reference architecture using the , an industry-recognized scenario-based approach.
