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.

Mobility Management for the Low‐Altitude Economy: Latency‐Aware Handover Design

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper develops a latency‐aware mobility‐management framework for aerial vehicles operating in hybrid terrestrial non‐terrestrial networks. We formulate a MILP for optimal AV AP association and propose a greedy handover policy using predicted coverage, rate and handover latency.

Closed‐Form Approximation of Average Error Probability With Finite‐Blocklength Coding Over Lognormal Wireless Communication Links

IET Communications, Volume 20, Issue 1, January/December 2026.
This work extends the Polyanskiy‐Poor‐Verdu (PPV) framework to lognormal wireless links. Specifically, the paper derives a closed‐form approximation for the average error probability under lognormal distribution, effectively generalizing the PPV analysis beyond the additive white Gaussian noise assumption.

Adaptable Bandwidth for Harmonic Step-Frequency Radar

International Journal of Antennas and Propagation, 2015
A spectrum sensing technique is described which is used to enhance the performance of harmonic step-frequency radar in the presence of harmful radio frequency (RF) interference (RFI). This technique passively monitors the RF spectrum for subbands of high

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 ...
