Distributed energy-efficient target tracking algorithm based on event-triggered strategy for sensor networks

The distributed estimation problem for wireless sensor networks with limited communication/sensing ranges and observability is studied. A novel sensor measuring activation scheme based on a fully distributed event-triggered strategy is proposed to make each node achieve a better trade-off between es...
