Presentation Transcript

  1. Centralized Mobile SensorGroup for Exploring Border of Target Area WCNC 2009 Kuen-Liang Sue and Jing-Wei Lin

  2. Outline • Introduction • Sensor Group Network Structure • Proposed Centralized SensorGroup Network • S-Shaped Sensing Mechanism • Simulation Results • Conclusion

  3. Introduction • Traditional - detect the environment by randomly deploying immobile sensors within the area. • Mobile - each MS moves and operates according to its current location. (wireless localization system) • SensorGroup (SG) - GPS receivers are organized into groups. (it is not cost-effective) • Anchor nodes - at least three anchors. (size is enlarged) • Centralized Mobile SensorGroup (CSG) - mobile anchor with GPS receiver
