Blockchain for Future Wireless Networks: A Decade Survey

Area of Science:

• Computer Science
• Network Security
• Cybersecurity

Background:

• Wireless networks (WNs) are crucial for intelligent services but vulnerable to security threats like data manipulation and denial-of-service attacks.
• Existing security solutions (cryptography, AI) show limitations in fully addressing these WN security challenges.
• The increasing demand for high data rates, low latency, and network capacity exacerbates these security concerns.

Purpose of the Study:

• To survey security and privacy issues in wireless networks (WNs).
• To explore the potential of blockchain technology as a robust solution for WN security.
• To analyze existing security solutions and propose a novel blockchain and 6G-based WN architecture.

Main Methods:

• Analysis of existing research on WN security requirements and issues across 4G, 5G, and 6G.
• Comparative analysis of current security solutions for WNs.
• Development and evaluation of a proposed blockchain and 6G-based WN architecture using performance metrics (scalability, packet loss, latency).

Main Results:

• Identified critical security issues in various generations of wireless networks.
• Demonstrated the significant influence of blockchain technology in enhancing WN security.
• The proposed architecture shows promising performance in scalability, packet loss ratio, and latency.

Conclusions:

• Blockchain technology is essential for securing wireless networks against evolving threats.
• The proposed blockchain and 6G architecture offers a viable path towards secure and efficient WNs.
• Further research is needed to address open issues and challenges in blockchain-based WN solutions.
