Abstract: Indoor localization for elderly monitoring is often performed using binary PIR sensors due to their advantages. However, elderly monitoring relies on good location resolution, and this latter requires large number of PIR sensors. To increase location resolution using few sensors, a multiplex binary structure is used, and to deal with ambiguities caused by such structure (e.g. zones sharing same code) we present a novel approach free from false alarm distribution assumptions.
