Dynamic Resource Allocation for 5G and Beyond Networks Slicing Based on Meta‐Federated Deep Reinforcement Learning

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This study introduces a meta‐federated deep reinforcement learning (Meta‐FedDRL) framework to address dynamic resource allocation (DRA) challenges in ultra‐dense and heterogeneous 5G and beyond network slicing. The proposed approach enables distributed learning while preserving data confidentiality and enhancing generalization.

A Hybrid Dynamic Sand Cat Swarm Optimisation (HD‐SCSO) Approach for Resource Allocation in Wireless Sensor Networks

open access: yesIET Wireless Sensor Systems, Volume 16, Issue 1, January/December 2026.
The hybrid dynamic sand cat swarm optimisation (HD‐SCSO) approach introduces a bioinspired method to enhance energy efficiency, data transmission and resource fairness in WSNs. Through adaptive clustering, intelligent node selection and real‐time adjustments, HD‐SCSO ensures optimised performance, extended network lifetime and seamless IoT integration,

On the Pointwise Threshold Behavior of the Binary Erasure Polarization Subchannels

open access: yesIEEE Transactions on Information Theory, 2017
It is shown that when Ankan's n-level polarization transformation is applied to the binary erasure channel, each of the resulting individual 2n subchannels has a sharp threshold, for sufficiently large n.

Full‐Scale Simulation and Performance Improvement of PEMFCs With Different Flow Channel Cross‐Sections

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Flow‐channel design plays a decisive role in the performance and water management of large‐scale proton exchange membrane (PEM) fuel cells (PEMFCs), especially for parallel flow fields (FFs) that feature low pressure drop but are prone to flow maldistribution.

Design of a Hilbert Curve Fractal MIMO Slot Antenna With Enhanced Bandwidth and Stable Radiation Patterns for Wi‐Fi 7 and Wi‐Fi 8 Applications Using Genetic Algorithm

open access: yesInternational Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
Next‐generation Wi‐Fi 7 (IEEE 802.11be) and Wi‐Fi 8 (IEEE 802.11bn) demand compact multielement antennas offering wide bandwidth, high isolation, and stable radiation within limited device space. Conventional MIMO designs often face strong coupling, narrow bandwidth, or low efficiency, restricting high‐throughput multilink performance.

Adaptive Subchannel Allocation For Mc-Cdma System

open access: yes, 2007
Multicarrier code-division multiple-access is one of the effective techniques to gain its multiple access capability, robustness against fading, and to mitigate the ISI. In this paper, we propose an improved mulcarrier CDMA system with adaptive subchannel allocation.

Signal Performance Characterization of Visible Light Nonorthogonal Multiple Access With Integrated Sensing and Communication Network

open access: yesInternational Journal of Optics, Volume 2026, Issue 1, 2026.
This paper exploits the signal performance characterization of visible light nonorthogonal multiple access (VL‐NOMA) for integrated sensing and communication (ISAC) network. The VL as a carrier uses light‐emitting diode (LED) to broadcast data to multiple users.
