Privacy-preserving and energy-efficient algorithm for secure and sustainable green wireless networks

In the current era, the demand for energy efficiency, security, and sustainability has increased due to the rapid development of wireless networks, especially in resource-constrained and environmentally friendly devices. However, to provide security to data while maintaining low energy utilization is a challenging task for such networks. To sustain security and privacy with energy efficiency, blockchain has been incorporated in this chapter. By implementing immutable and decentralized ledger with lightweight cryptographic solution incorporated with blockchain ensure data integrity, secure communication, decentralization, and traceability without relying on a central authority. To improve energy efficiency and privacy of the proposed algorithm, an effective cluster-based routing mechanism in which cluster heads are chosen based on an integrated trust weight metric that includes various parameters such as energy level, residual energy, and reputation value. The simulated results of the proposed scheme are compared to existing algorithms and simulated results of the proposed scheme proves its effectiveness in terms of privacy and energy.
