Abstract
Ensuring secure and accurate node localization in Underwater Wireless Sensor Networks
(UWSN) is a significant challenge, as conventional methods tend to neglect the security
risks associated with malicious node interference. This research addresses this issue by
proposing a Joint Trust-based Detection and Signature-based Authentication (JTDSA)
technique, aimed at improving both the security and accuracy of node localization in
UWSNs. The technique utilizes Intrusion Detection System (IDS) methods to calculate
the trust values of secondary-anchor nodes (SNs), ensuring only the most trusted SNs are
selected. Furthermore, a digital signature algorithm secures the Received Signal Strength
(RSS) data from tampering. The method incorporates a hybrid approach combining Angle
of Arrival (AoA) and RSS ranging techniques to achieve robust localization. Simulation
results demonstrate that JTDSA improves localization accuracy by 4% compared to exist
ing methods, achieving an overall accuracy of 99.2%. The technique also reduces packet
drop by 35% and enhances attack detection accuracy by 3%. These results indicate that the
proposed JTDSA technique offers an effective solution for secure and reliable localization
in UWSNs
