DRL‐Based Joint Clustering and Trajectory Optimization for UAV‐Assisted Emergency Networks
IET Communications, Volume 20, Issue 1, January/December 2026.6G is expected to see unprecedented data traffic surges. UAV‐assisted MEC aids emergency communications but faces challenges from dynamic user mobility and heterogeneous tasks. To address these, the proposed KM‐PPO integrates interference‐aware k‐means clustering (for user aggregation and initial UAV deployment) and PPO (for stable policy updates and ...

Transformer‐Based Fusion for Joint Routing and Resource Allocation in the Internet of Things
IET Communications, Volume 20, Issue 1, January/December 2026.In this work, we investigate decentralized joint routing and resource allocation for high‐quality path establishment at the network layer of the Internet of Things (IoT). We propose a novel optimization framework based on Transformer‐based Deep Reinforcement Learning (DRL), which enables the fusion of observations and actions along communication paths.

IET Communications, Volume 20, Issue 1, January/December 2026.This study presents a Strength Pareto Evolutionary Algorithm 2 (SPEA2)‐based multi‐objective framework for optimised deployment of drone base stations (DBSs) in Internet of Things (IoT) networks. The model simultaneously enhances user coverage and reduces path loss under realistic urban propagation conditions. Results confirm the framework's ability to

Energy‐Efficient Element Selection in RIS‐Assisted Backscatter Communication Systems
IET Communications, Volume 20, Issue 1, January/December 2026.This paper investigates energy‐efficient reconfigurable intelligent surface (RIS) assisted ambient backscatter communication systems with energy‐harvesting tags. A low‐complexity RIS element selection strategy is developed to satisfy both energy‐harvesting and signal‐to‐interference‐plus‐noise ratio constraints while minimizing overall power ...

IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes Geo‐FedKD, a geometry‐aware framework for dual‐connectivity UAV trajectory optimisation. Exploiting the observation that dual‐connectivity requirements naturally favour elliptical UAV trajectories with foci at the base station and the user centroid, Geo‐FedKD guides policy exploration towards feasible regions instead of relying ...

Next-Generation Wireless Backhaul Design for Rural Areas
IEEE Transactions on Network and Service ManagementRural areas often face significant challenges in accessing reliable broadband Internet due to high infrastructure costs and low population density. To address this issue, we propose a model for evaluating the performance and the cost of a mesh-based, last- and middle-mile replacement for broadband connection in these underserved regions.
