Secure Beacon Node Selection for Localization in Underwater Acoustic Sensor Networks

Localization is a widespread challenge in the underwater environment because several essential applications involve node locations, including attack detection, object acquisition, and surveillance. Precision localization and the security of the cluster members are popular research areas in underwater acoustic sensor networks (UASNs). Unfortunately, only a small percentage of research pays attention to the reliability and safety of the beacon node in UASNs. To provide security in underwater localization, this manuscript has presented a secure beacon node selection for localization technique in UASNs. The suggested methodology employs trust-based calculations to help unknown nodes identify the utmost dependable beacon nodes. The proposed procedure is split into three sub-stages based on the trust management scheme: trust assessment of beacon nodes, selecting trustworthy beacon nodes, and the localization of target nodes using the selected secure beacon nodes. The performance shows the proposed scheme’s effectiveness in terms of localization error, coverage, and malicious node detection rate is better than others.
