Area of Science:

  • Oceanography
  • Computer Science
  • Network Engineering

Background:

  • The Internet of Underwater Things (IoUT) enables widespread environmental monitoring via underwater wireless sensor networks (UWSNs).
  • Accurate event detection and source localization are crucial for timely responses in dynamic underwater environments.

Purpose of the Study:

  • To develop a novel technique for detecting event coverage and determining event sources in UWSNs.
  • To enhance the efficiency and accuracy of underwater event monitoring systems.

Main Methods:

  • A technique is proposed where deviations in sensory data from neighboring sensor nodes indicate a potential event.
  • A relay node collects and routes data to sink nodes for analysis.
  • Event coverage is represented as a weighted graph, with deviations determining edge weights.
  • Event sources are identified as barycenters within this graph.

Main Results:

  • The developed technique effectively detects event coverage and determines event sources.
  • Experimental results demonstrate superior energy efficiency compared to existing methods, particularly in steady network topologies.
  • The graph-based representation accurately models event characteristics and source locations.

Conclusions:

  • The proposed technique offers an energy-efficient solution for event detection and source localization in IoUT environments.
  • This approach enhances the reliability and responsiveness of underwater monitoring systems.
  • The method shows significant promise for applications requiring robust underwater sensing and data analysis.
