In this paper, we will describe the implementation and experimental analysis of a wireless sensor network application for e-Health. The main idea of the application is to use simple distributed sensor nodes in a home environment, to provide home assistants, nurses, healthcare centers and relatives with a degree of "understanding" and information about the actual persons health and activity status in order to fast determine what kind of help is needed. Another feature of the with the sensor application is the application of localization and tracking within the home environment. We propose a simple localization algorithm based on special sensor data and received signal strength indicator (RSSI) which has a low complexity suitable for small sensor networks. The experimental results show that the proposed algorithm works fine in a home environment.
