In this article, we will discuss and evaluate a prototype of a wireless sensor network (WSN) elderly healthcare at primary care center and residential home. The main functions are to provide users (home assistants etc) with a degree of "understanding" of information about him, such that what he is doing, where he is, what his health activity is. One major feature in our experimental e-health prototype is positioning which can be used for determine the localization of the elderly in the apartment. For tracking and localization, we have proposed a positioning algorithm which is based on passive positioning. The obtained experimental results show that this prototype has high accuracy in localization and tracking.
