UAVs‐Assisted Low‐Bit Quantized CF‐mMIMO Systems With MmWave Communications Under MRC Detection

IET Communications, Volume 19, Issue 1, January/December 2025.
ABSTRACT The cell‐free massive multiple input multiple output (CF‐mMIMO) approach, due to its high coverage and the ability to attenuate the large‐scale fading impacts in wireless communications, has drawn a lot of attention. Additionally, because of their movement ability, low power, and low‐cost employed infrastructures, unmanned aerial vehicles ...

Access Point Selection and Localization for Cluster‐Based Realization of a Device‐to‐Device Cell‐Free 6G Communications Network

IET Communications, Volume 19, Issue 1, January/December 2025.
We introduce a fully distributed framework that leverages belief‐desire‐intention extended (BDIx) agents on user devices to perform dynamic clustering and access‐point selection in a cell‐free 6G network, using both classical and deep‐learning methods for deterministic, scalable AP grouping.

An improved affinity propagation method for maximising system sum rate and minimising interference for 3D multi‐UAV placement in disaster area

IET Networks, Volume 14, Issue 1, January/December 2025.
In emergency situations where ground base stations are disabled, UAVs, due to their low cost and high adaptability, restore communication coverage in remote areas. The main challenge is optimally determining the three‐dimensional positions of the UAVs to meet dynamic user demand and reduce interference.

Adaptive power management for multiaccess edge computing‐based 6G‐inspired massive Internet of Things

IET Wireless Sensor Systems, Volume 15, Issue 1, January/December 2025.
The paper proposes a containerised edge computing model for power optimisation in 6G‐inspired massive Internet‐of‐Things applications. The problem is formulated as a central processing unit energy consumption cost function based on quasi‐finite system observations. Results show that the model performs better compared to a competitive baseline algorithm.
