Task-Oriented Edge Networks: Decentralized Learning Over Wireless Fronthaul

IEEE Internet of Things Journal
This paper studies task-oriented edge networks where multiple edge internet-of-things nodes execute machine learning tasks with the help of powerful deep neural networks (DNNs) at a network cloud. Separate edge nodes (ENs) result in a partially observable system where they can only get partitioned features of the global network states.

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.

Genetic Algorithm Assisted Hybrid Beamforming for Wireless Fronthaul

, 2018
This paper proposes a genetic algorithm assisted hybrid signal to leakage plus noise ratio (SLNR) beamforming design for wireless fronthaul scenario. The digital precoder of the proposed hybrid SLNR beamforming is expressed in closed-form. Highly limited phase resolution (one-bit resolution) is assumed at the phase shifters at the analog precoder.

Microservice Adaptability and Self‐Organization of UAV‐Assisted Wireless Networks in Failure Rural Scenarios

International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.
Internet access remains unavailable for approximately 2 billion people in remote areas, limiting their access to essential services such as healthcare and education. This paper presents a UAV‐based wireless network architecture combined with a microservice model to ensure the dynamic deployment of IoT applications in rural environments.

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 ...
