Area of Science:

  • Computer Science
  • Electrical Engineering
  • Network Engineering

Background:

  • Wireless sensor networks (WSNs) face challenges in accurately detecting small events due to grid-based limitations.
  • Existing methods struggle with event detection performance when the event region is smaller than the grid size.

Purpose of the Study:

  • To propose an enhanced grid-based distributed event detection scheme for WSNs.
  • To improve event detection accuracy and minimize false alarms in WSNs.

Main Methods:

  • The proposed scheme divides each grid into 2x2 sub-grids.
  • Event detection decisions are made by identifying a 2x2 sub-grid region exceeding a threshold, utilizing inter-cluster communication among cluster heads.
  • A dynamic threshold adjustment mechanism is incorporated.
