HybridEdge: A Lightweight and Secure Hybrid Communication Protocol for the Edge-Enabled Internet of Things

The Internet of Things (IoT) and edge-assisted networking infrastructures are capable of bringing data processing and accessibility services locally at the respective edge rather than at a centralized module. These infrastructures are very effective in providing a fast response to the respective queries of the requesting modules, but their distributed nature has introduced other problems such as security and privacy. To address these problems, various security-assisted communication mechanisms have been developed to safeguard every active module, i.e., devices and edges, from every possible vulnerability in the IoT. However, these methodologies have neglected one of the critical issues, which is the prediction of fraudulent devices, i.e., adversaries, preferably as early as possible in the IoT. In this paper, a hybrid communication mechanism is presented where the Hidden Markov Model (HMM) predicts the legitimacy of the requesting device (both source and destination), and the Advanced Encryption Standard (AES) safeguards the reliability of the transmitted data over a shared communication medium, preferably through a secret shared key, i.e., , and timestamp information. A device becomes trusted if it has passed both evaluation levels, i.e., HMM and message decryption, within a stipulated time interval. The proposed hybrid, along with existing state-of-the-art approaches, has been simulated in the realistic environment of the IoT to verify the security measures. These evaluations were carried out in the presence of intruders capable of launching various attacks simultaneously, such as man-in-the-middle, device impersonations, and masquerading attacks. Moreover, the proposed approach has been proven to be more effective than existing state-of-the-art approaches due to its exceptional performance in communication, processing, and storage overheads, i.e., 13%, 19%, and 16%, respectively. Finally, the proposed hybrid approach is pruned against well-known security attacks

Kidney disease (KD) is a gradually increasing global health concern. It is a chronic illness linked to higher rates of morbidity and mortality, a higher risk of cardiovascular disease and numerous other illnesses, and expensive medical expenses. The machine learning (ML) models are applied for KD prediction with higher accuracy and precision. The KD dataset has uncertainty and vague information, so, we used the neutrosophic set (NS) to deal with vague and uncertainty information in the KD dataset. The KD dataset is converted into the N-KD dataset with three membership functions: truth, indeterminacy, and falsity. Three ML models are used in this study such as logistic regression (LR), support vector machine (SVM), and k-nearest neighbor (KNN). These ML models are applied to the N-KD dataset. The results show the LR has higher accuracy and precision on the N-KD dataset than the original KD dataset. © 2025, University of New Mexico. All rights reserved.

The annual Hajj pilgrimage presents a unique logistical challenge for healthcare institutions, with the need to efficiently manage medical supplies for millions of participants. Traditional methods often fall short in transparency, efficiency, and rapid response. This paper proposes a novel Blockchain-Enabled Medical Supply Chain Architecture for Rapid Response in Hajj, a framework specifically tailored to address the special requirements of this large-scale event. Leveraging the decentralized nature of blockchain technology, this solution integrates smart contracts, Internet of Things (IoT) sensors, and mobile applications to automate supply chain operations and enable real-time monitoring. The proposed architecture emphasizes secure data management, transparent tracking, and automation, facilitating quick reactions to medical emergencies. Future work involves the implementation and comprehensive evaluation of this architecture, with a focus on real-world efficiency, responsiveness, and alignment with healthcare regulations. By modernizing the Hajj medical supply chain, this innovation aims to enhance pilgrim safety and set a benchmark for large-scale event healthcare logistics. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
