ALFA: A Software Architecture for Bounded Incremental Firmware Updates in Energy‐Constrained LoRa‐Based IoT Systems

IET Smart Cities, Volume 8, Issue 1, January/December 2026.
Firmware Update Over‐The‐Air (FUOTA) in LoRaWAN is constrained by duty‐cycle regulations, limited payload sizes and energy variability, resulting in prolonged update latency. This work identifies build‐induced structural volatility as a key factor inflating differential patch sizes and proposes ALFA, an architectural and linker‐enforced framework that ...

FragCast: A Scalable BLE‐Based OTA Framework for Constrained IoT Devices

IET Wireless Sensor Systems, Volume 16, Issue 1, January/December 2026.
In this research work, we propose and evaluate a novel OTA protocol that leverages the one‐to‐many broadcast paradigm of BLE. Our contribution is an application‐layer protocol that transports firmware fragments within custom‐formatted BLE advertising packets.

A Systematic Review of VANET Routing Protocols for Intelligent Transport Systems (ITSs)

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
The swift improvement of wireless communication technology has aided the creation of vehicular ad hoc networks (VANETs) as a revolutionary option for the realization of intelligent transportation systems (ITSs). VANETs facilitate seamless communication between vehicles and infrastructure (V2I) and among the vehicles themselves (V2V). These networks can

Reliable Deep Learning–Assisted Spectrum Sensing for Cognitive Radio and 6G Wireless Networks

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
Reliable spectrum sensing is a key requirement for cognitive radio (CR) networks; however, its performance is significantly degraded by fading, noise uncertainty, and channel estimation errors. This paper proposes a hybrid gated recurrent unit–long short‐term memory–convolutional neural network (GRU–LSTM–CNN) framework for cooperative spectrum sensing (
