Autonomous Attack Mitigation Through Firewall Reconfiguration

International Journal of Network Management, Volume 35, Issue 1, January/February 2025.
This graphical abstract shows the workflow of the proposed approach for autonomous attack mitigation through firewall reconfiguration. ABSTRACT Packet filtering firewalls represent a main defense line against cyber attacks that target computer networks daily. However, the traditional manual approaches for their configuration are no longer applicable to

Adaptive Resource Management Framework for Profit Optimisation in 5G Network Slicing

IET Networks, Volume 14, Issue 1, January/December 2025.
This paper proposes a novel optimisation framework for dynamic resource management in 5G network slicing, integrating integer linear programming (ILP) and heuristic models to prioritise high‐revenue slices while minimising reconfiguration costs. Simulations show a 24.8% increase in resource utilisation and a 98.99% boost in profitability compared to a ...

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.

A hierarchical reinforcement learning approach for energy‐aware service function chain dynamic deployment in IoT

IET Communications, Volume 18, Issue 18, Page 1231-1243, November 2024.
We provide a convolutional neural network‐based hierarchical reinforcement learning approach to lower total energy consumption and carbon emissions in the dynamic service function chaining situations. This method can more effectively lower energy consumption and carbon emissions when compared to other hierarchical algorithms based on conventional deep ...
