QoE‐based dynamic resource allocation for heterogeneous smart distribution grids

IET Communications, Volume 19, Issue 1, January/December 2025.
This article introduces an innovative metric termed as Quality of Experience (QoE) by amalgamating the terminal operations concerning data rate, latency, and packet loss rate. With the aim of maximizing the QoE, we design a dynamic resource allocation scheme in a heterogeneous wireless communication and power line communication network.

Performance Enhancement of Indoor VLC Systems Using DPSS‐Based DCO‐GFDM Modulation

IET Communications, Volume 19, Issue 1, January/December 2025.
VLC is a promising solution for future wireless communication systems due to its high data rate, wide bandwidth, and enhanced security features. However, challenges such as high PAPR and OOB spectral leakage limit its performance. In this study, we propose the integration of DPSS with DCO‐GFDM to enhance the performance of indoor VLC systems.

Robust Connectivity in 6G Enabled Indoor VLC Networks Using Intelligent Reflecting Surfaces

IET Communications, Volume 19, Issue 1, January/December 2025.
Visible light communication (VLC) in 6G optical networks offers high data rates with extended network coverage. The challenge is that these VLC networks are susceptible to signal obstructions that lower line‐of‐sight (LoS) link quality. This paper proposes a novel framework that uses Intelligent reflecting surfaces, which provide improved non‐LoS ...

Experimental demonstrations of high‐accuracy 3D/2D indoor visible light positioning using imaging multiple‐input multiple‐output receivers and artificial neural networks

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.
The paper proposes and demonstrates a high‐precision indoor 2D and 3D visible light positioning system using an imaging MIMO configuration with supervised ANN, achieving positioning accuracies of 3.7 mm (2D) and 51 mm (3D) experimentally. A simulation model verifies the results and optimises the system, improving accuracies to 2 mm (2D) and 14.7 mm (3D)
