Abstract :
The work presents the development of a navigation system based on wireless sensor networks specially designed for elderly care applications. The main constraints of the application scenario are analysed and the tracking algorithm is designed following the application constraints. The tracking is done by the fusion of RSSI measurements using the weighted centroid algorithm to compute the position and inertial sensors to compute the heading and speed by means of a step detection. The measurement information is processed using an Extended Kalman Filter.
