Decision‐Stability and Regret Diagnostics for Reinforcement Learning Based Handover in Vehicular Mobility

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a regret‐aware evaluation framework for reinforcement‐learning‐based base station handover in vehicular networks, with a focus on decision stability under fast mobility. An actor critic handover policy is evaluated against an oracle reference using regret diagnostics to quantify decision quality beyond average performance metrics ...

A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

Leveraging GRU Networks for Robust and Efficient Vehicular Channel Estimation

IET Communications, Volume 20, Issue 1, January/December 2026.
Precise channel estimation becomes vital in robust vehicular communication, particularly in high‐mobility scenarios where conventional techniques such as Least Squares (LS), Minimum Mean Square Error (MMSE), Data Pilot‐Aided (DPA), and Orthogonal Matching Pursuit (OMP) methods frequently fail owing to error propagation and computational inefficiencies.

Neuro‐Symbolic TabNet for Explainable Congestion Management in Vehicular Ad Hoc Networks (VANETs)

IET Communications, Volume 20, Issue 1, January/December 2026.
Using the VANET Traffic Congestion Dataset, we preprocess heterogeneous traffic, communication and environmental features, train an enhanced TabNet model with contextual embeddings and distil its behaviour into a compact set of human‐readable rules with quantified coverage, confidence and fidelity.

Towards Adaptative Cyber‐Physical Transportation System: From Knowledge Elicitation to Meta‐Architecture Based on Clustering Algorithm

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
This article proposes a meta‐architectural framework for cyber‐physical transportation systems (CPTS) that integrates physical infrastructure with cyber components through knowledge elicitation and a clustering‐based design structure matrix (DSM). The approach enables adaptive system behaviour, improves interoperability and supports sustainable urban ...
