The growing demand for high-speed, low-latency, and high-capacity wireless networks (WNs) is driven by the rise of advanced applications like intelligent transportation systems, smart homes and cities, and industrial automation. However, these vital networks face significant security threats, such as data tampering, injection attacks, service disruption, man-in-the-middle attacks, and session hijacking, which compromise their performance and reliability. While security measures like encryption, artificial intelligence (AI), access control, and authentication have been proposed, they haven’t fully addressed these challenges. To secure WNs against these evolving threats, a more robust solution is needed. Blockchain technology, with its inherent features of decentralization, stability, transparency, and security, offers a promising path forward. By implementing blockchain, WNs can establish a secure, irreversible ledger for data transactions and communications. This technology can also transparently and efficiently manage the allocation and sharing of crucial network resources, such as spectrum and computing power. Ultimately, blockchain can safeguard data integrity and confidentiality, addressing critical privacy concerns and enabling the full potential of WN-based intelligent services.
