TARIQ: Towards Area Adjustment and Rounding of Intermediate Nodes for Quadrilateration in Blockchain Enabled Underwater Beacon Node Localization

Blockchain Enabled IoT-Underwater Acoustic Sensor Networks (IoT-UASNs), is self-organized heterogeneous wireless network which attract a lot of attention from research community. Moreover, in the fields of marine search and water environment monitoring, blockchain uses several sensors for identify the unknown location of nodes. Therefore, the current research in underwater emphasizes the adoption of blockchain localization algorithm that can calculate and secure the unknown node's location with authenticate accuracy and improve its efficiency and localization error. Therefore, we will induce blockchain in underwater with proposing area adjustment and rounding of nodes. Many mechanisms are present for rounding of localization like bilateration, trilateration's and quadrilaterations. The proposed scheme employs quadrilaterations for localization (as it is extended form of all lateration), that provides the low E2E delay, energy consumption, localization error, transmission loss and achieve high packet delivery ratio. Extensive simulations have been run to demonstrate the proposed scheme's performance superiority over state-of-the-art schemes.
