In this paper, we consider and analyze the performance of exploiting simultaneously wireless information power transfer (SWIPT) for coordinated-non-orthogonal multiple access (NOMA) systems under Nakagami- m fading channels. Specifically, to deal with limited energy issues at relay unit while taking into reusing resource efficiency, propose use SWIPT-based splitting mechanisms in conjunction NOMA approaches by means proposing two separate scenarios, first focus is on forward-based device-to-device (D2D) transmissions, called SWIPT-NOMA-D2D, second forwarding signal only, SWIPT-NOMA-noD2D. Evaluating case case, derive exact approximate closed-form expressions outage probabilities cell-center cell-edge users, respectively. Besides, also obtain an solution ergodic rate message transmission, which enables us effectively characterize system spectrum utilization. The correctness our analyses tightness approximation developed are validated through Monte Carlo simulations numerical techniques. Finally, show that proposed schemes achieve near sum cases unconstrained designs their effectiveness improving centre-cell users.

Taking Advantage of the Mistakes: Rethinking Clustered Federated Learning for IoT Anomaly Detection

IEEE Transactions on Parallel and Distributed Systems, Journal Year: 2024, Volume and Issue: 35(6), P. 862 - 876

Published: March 21, 2024

Clustered federated learning (CFL) is a promising solution to address the non-IID problem in spatial domain for (FL). However, existing CFL solutions overlook issue temporal and lack consideration of time efficiency. In this work, we propose novel approach, called ClusterFLADS , which takes advantage false predictions inappropriate global models, together with knowledge temperature scaling catastrophic forgetting reveal distributional similarities between training data (of different clusters) test data. Additionally, design an efficient feature extraction scheme by exploiting role each layer neural network's process. By strategically selecting model parameters using PCA dimensionality reduction, effectively improves clustering speed. We evaluate real-world IoT trace various scenarios. Our results show that accurately efficiently clusters clients, achieving $100\%$ true positive rate low positives across distributions both domains.

A Novel Three-Factor Authentication Protocol for Multiple Service Providers in 6G-Aided Intelligent Healthcare Systems

IEEE Access, Journal Year: 2022, Volume and Issue: 10, P. 28975 - 28990

Published: Jan. 1, 2022

6G technology is now attracting many scientific researchers due to its prominent features including high mobility, data rate, operating frequency, and ultra-low end-to-end delay. Compared the 5G, has certain advantages that can transform smart healthcare a new advanced intelligent system, where multiple issues concerns of services (e.g., slow ambulance response) are effectively resolved. In such communication patients service providers communicate with each other via an open internet channel. Since important very sensitive, security privacy in network become prominent. this paper, we introduce 6G-aided environment. Our work also proposes solution called Centerless User-Controlled Single Sign-On (CL-UCSSO) for achieving convenient cost-saving multi-server system constructed. A three-factor mechanism (combining card, password biometrics) time bound property integrated design protocol fast authentication allows efficiently establish secure communications. Security proof proposed provided using well-known verification tools RoR model, AVISPA simulation BAN logic.

Falsification Detection System for IoV Using Randomized Search Optimization Ensemble Algorithm

IEEE Transactions on Intelligent Transportation Systems, Journal Year: 2023, Volume and Issue: 24(4), P. 4158 - 4172

Published: Jan. 9, 2023

Falsification detection is a critical advance in ensuring that real-time information about vehicles and their movement states certified on the Internet of Vehicles (IoV). Thus, detecting nodes are propagating inaccurate requirement for successful deployment IoV services although only few research studies have been carried out Basic Safety Message (BSM) falsification. As such, this paper proposes Randomized Search Optimization Ensemble-based Detection Scheme (RSO-FDS). The RSO technique was used to construct proposed Random Forest (RF) model. evaluation performed three different datasets developed evaluate falsification IoV. In addition, six most popular supervised learning (SL) algorithms were investigated capability RSO-FDS, which had best performance across all datasets. metrics considered computational efficiency terms prediction time, validation accuracy overall attack classification, precision, recall, F1 scores. For validation, RSO-FDS further compared with results from recent works. Furthermore, irrelevance data balancing illustrated real-life scenarios. result shows model outperformed state-of-the-art implemented work related
