Abstract

In this paper, path loss measurements performed with low cost MicaZ modules used for on-body wireless sensor networks have been shown. By combining the experimental activities with simulation results based on simple canonical geometries, it has been possible to extract some simple path loss models. Time domain properties of the field attenuation are also under investigation. The path loss data will be elaborated to classify a set of typical human postures and activities, and results will be shown at the conference.
