Enhancing Security and Efficiency in Wireless Mobile Networks through Blockchain

The evolution of wireless mobile networks (WMNs) towards supporting advanced applications—such as next-generationsmart cities, autonomous vehicles, and industrial IoT—demands enhanced data rates, lower latency, and increased network capacity. However, these advancements introduce complex security challenges, including data tampering, unauthorized access, serviceinterruptions,andcyberattacksthatthreatentheintegrityofWMNapplications.Traditionalsecuritymechanisms,such as encryption, artificial intelligence, and access control, while beneficial, often fall short of providing comprehensive protection againsttheseevolvingthreats.Blockchaintechnology,withitsdecentralized,transparent,andsecureinfrastructure,emergesas a transformative solution for addressing these vulnerabilities in modern wireless networks. By implementing blockchain, WMNs can achieve a tamper-proof, immutable ledger that supports secure data sharing, access management, and resource allocation. Blockchain’s decentralized consensus mechanisms allow for reliable user authentication, while its transparency enhances trust among devices, making it ideal for managing data confidentiality, trust, and resource efficiency in WMNs. This paper explores the roleof blockchain in fortifying security in wireless mobile networks, particularly focusing on the potential of blockchain to meet the requirements of emerging wireless standards and technologies, such as 5G and 6G, which prioritize high data throughput, low latency, and robust privacy.
