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.

Design and Optimization of a Phase‐Tunable Mixer Based on Cascaded Dual‐Drive Mach–Zehnder Modulator Considering Nonlinear Behavior of Modulator

International Journal of Optics, Volume 2025, Issue 1, 2025.
This paper proposes a novel phase‐tunable mixer based on a cascaded dual‐drive Mach–Zehnder modulator (DDMZM), designed to address the critical need for simultaneous frequency mixing and precise phase control in phased array antennas. Unlike conventional mixers, the proposed structure uniquely combines frequency mixing and phase tuning, enabling ...

Fronthaul-Constrained Distributed Radar Sensing

2024 IEEE Globecom Workshops (GC Wkshps)
In this paper, we study a network of distributed radar sensors that collaboratively perform sensing tasks by transmitting their quantized radar signals over capacity-constrained fronthaul links to a central unit for joint processing. We consider per-antenna and per-radar vector quantization and fronthaul links with dedicated resources as well as shared
