Security mechanisms and Vulnerabilities in LPWAN

IOP Conference Series: Materials Science and Engineering, 2018
The count of Internet of things (IoT) devices getting connected to internet are exponentially growing and is proposed to be 75 billion by 2025. IoT devices uses Low Power Wide Area Network (LPWAN) that are precisely build to operate at a lower cost with greater power efficiency and long range connectivity than traditional wireless networks.

Current State of Accountants' Knowledge of Digital Technologies: Evidence From Australia and New Zealand

Accounting &Finance, Volume 65, Issue 3, Page 2649-2664, September 2025.
ABSTRACT Using survey research, we investigate accountants' self‐rated knowledge of a variety of digital technologies (DTs). We find that accountants' self‐rated knowledge of established DTs is almost in line with IES2 requirements, but their self‐rated knowledge of emerging DTs is significantly below IES2 requirements. Of greater concern, we find that

Energy‐Aware RF Fingerprinting for Device Identification in Ultra‐Low‐Power IoT Systems

Engineering Reports, Volume 7, Issue 7, July 2025.
We propose an energy‐aware RF fingerprinting method for ultra‐low‐power IoT using two deep learning models. RFNet achieves 97.48% accuracy while TinyRFNet reaches 93.19% with far fewer parameters. Dynamic model selection by battery level and confidence yields 94.54% accuracy and 17% energy savings.
