Indoor Room Location Estimation
Abstract
This paper presents an indoor location estimation system, especially to locate people or objects at room level. First of all a theoretical approach is given. Secondly, a practical case, using our own system, is presented. Our system consists of a ZigBee-based wireless sensor network connected to a central PC. Using the signpost algorithm and considering the behavior of the received signal strength (RSS) through walls, floors and ceilings, we succeeded in developing a reliable indoor room localization system.
