Abstract :
The accuracy of RF propagation models for distance measurement between WSN nodes using received signal strength indicator (RSSI) was studied. We implemented two simple propagation models, the free space log-normal model and 2-ray ground reflection model. The results show, that first model is not very precise in closed space (rooms). The second model gives quite well agreement with experimental RSSI measurements for greater distances between transmitting and receiving nodes.
