Finite State Machine of the MQTT-SN Protocol for Its Operation Over IEEE 802.15.4 in Linear Topologies

IEEE Access
Currently, the Message Queuing Telemetry Transport for Sensor Networks (MQTT - SN) protocol has been implemented in operating systems such as TinyOS and Contiki to operate above the network layer, in sensor nodes with low processing capacity, powered by ...

CoAP vs. MQTT-SN: Comparison and Performance Evaluation in Publish-Subscribe Environments [PDF]

2021 IEEE 7th World Forum on Internet of Things (WF-IoT), 2021
The Publish/Subscribe communication pattern has proved to be particularly tailored to the IoT world, with the MQTT protocol being the nowadays standard de-facto for IoT applications. Request/response protocols explicitly designed for the IoT, such as CoAP, have been revised to support also Publish/Subscribe.

Security Assessment of the MQTT-SN Protocol for the Internet of Things

Journal of Physics: Conference Series, 2022
Abstract The Internet of Things (IoT) is growing globally at a fast pace. However, the expansion of the IoT paradigm has brought with it the challenge of promptly detecting and evaluating attacks against these systems. The Message Queuing Telemetry Transport (MQTT) protocol is one of the most used protocols in the IoT scenario due to its

Lightweight Security for MQTT-SN

International Journal of Engineering & Technology, 2018
This study discusses a method to secure Message Queuing Telemetry Transport-Sensor network (MQTT-SN). MQTT-SN is a popular data communication protocol used in developing IoT applications and can be secured by augmenting it with a security scheme. In this work, several lightweight encryption schemes to be used in tandem with MQTT-SN were tested and ...

PharmaChain: A blockchain to ensure counterfeit‐free pharmaceutical supply chain

IET Networks, Volume 12, Issue 2, Page 53-76, March 2023., 2023
Abstract Globalisation has facilitated different industries to eliminate geographical boundaries and equipped organisations to work collectively to produce goods. Pharmaceuticals is one such industry which has majorly benefited from globalisation to reduce costs and increase profitability at different aspects of research, development, manufacturing of ...

[Retracted] Data Acquisition through Mobile Sink for WSNs with Obstacles Using Support Vector Machine

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022
Mobile sink‐based data collection in wireless sensor networks has become an attractive research area to mitigate hotspot issues. It further increases the efficiency of the WSN, such as throughput, lifetime, and energy efficiency, while decreasing delay and packet losses.

QSLT: A Quantum‐Based Lightweight Transmission Mechanism against Eavesdropping for IoT Networks

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
Quantum Key Distribution (QKD) is a promising paradigm for Internet of Things (IoT) networks against eavesdropping attacks. However, classical quantum‐based mechanisms are overweight and expensive for resource‐constrained IoT devices. That is, the devices need to frequently exchange with the QKD controller via an out‐band quantum channel. In this paper,
