FC-FTCP: a lightweight fault-tolerant clustering protocol for secure IoT data transmission

Area of Science:

• Computer Science
• Network Security
• Internet of Things

Background:

• Internet of Things (IoT) enables device communication but faces security and latency challenges.
• Unauthorized access, data breaches, and transmission delays hinder IoT application efficiency.
• Existing solutions often lack comprehensive security and efficient resource management for IoT.

Purpose of the Study:

• To propose a Fog Computing-based Fault-Tolerance Clustering Protocol (FC-FTCP) for enhanced IoT security and reliability.
• To integrate lightweight cryptography and Off-the-Record (OTR) authentication for robust data protection.
• To improve decentralized data processing, fault-tolerant routing, and energy efficiency in IoT networks.

Main Methods:

• Development of the Fog Computing-based Fault-Tolerance Clustering Protocol (FC-FTCP).
• Integration of lightweight cryptography and Off-the-Record (OTR) authentication mechanisms.
• Simulation-based evaluation of protocol performance against existing methods.

Main Results:

• FC-FTCP achieved 98.45% efficiency and 95.12% data authentication accuracy.
• Demonstrated significant reductions in network overhead (21.19%) and latency (15.13%).
• Reported computational overhead of 9.5 ms and a 23.12% reduction in computational cost.

Conclusions:

• FC-FTCP offers superior secure data handling and resource optimization for IoT environments.
• The protocol effectively addresses security vulnerabilities and latency issues in IoT deployments.
• FC-FTCP is a suitable solution for low-power IoT applications requiring high reliability and security.
