Abstract
The long propagation delay of sensor nodes' messages and flexibility are the mobile target localization scheme's principal tasks in Underwater Wireless Sensor Network (UWSN). As propagation delay is one of the principal aspects, disturbing the time harmonisation of underwater sensor nodes, a long-lasting delay must be assessed and adjusted to attain precise localization. In this article, we suggest an energy-efficient localization scheme based on Mobility and Propagation delay prediction. The system model comprises Surface buoys that drift on the water surface, Anchor nodes which drift at various water depths and Ordinary nodes that are extensively disseminated at different profundity. Anchor node mobility prediction procedure is intended to analyze and record its speed at every localization period. Then, the propagation delay is expected and compensated to attain precise localization. The ordinary nodes make localization, utilizing the expected speed vectors got from the anchor nodes. The replicating outcomes, exhibit that the suggested method increases overall energy efficiency.
