TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

Radio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

Regularised Hyper Parameter Bi Level Optimisation With Continual Learning Based Deep Neural Network for Beamforming in Ultra‐Wide Band System

IET Communications, Volume 20, Issue 1, January/December 2026.
This research proposes a Regularised Hyperparameter Bilevel Optimisation with Continual Learning‐based Deep Neural Network (RHBO‐CLDNN) for beamforming in an Ultra‐Wide Band (UWB) system. The RHBO ensures the hyperparameter efficiency at both upper and lower levels, which allows DNN to fine‐tune the unique characteristics of the UWB system, which leads

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

Uncertain Data Clustering-Based Distance Estimation in Wireless Sensor Networks

Sensors, 2014
For communication distance estimations in Wireless Sensor Networks (WSNs), the RSSI (Received Signal Strength Indicator) value is usually assumed to have a linear relationship with the logarithm of the communication distance.

Edge‐Enabled DSRC Deployment in Highway Scenarios for Vehicle Lane Positioning and Driving Patterns Tracking

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study proposes an enhanced vehicle tracking method that fuses GPS/INS data with RSSI signals in a connected vehicle environment to overcome the limitations of embedded sensors during abrupt manoeuvres. By employing an interacting multiple model algorithm that combines linear and non‐linear estimators, the method improves trajectory estimation and ...
