Could someone point out related paper/data that shows the RSSI propagation
model in sensor networks?
that is, the function of RSSI received powers with distance between two nodes?
There is nothing special about propagation by sensor nodes -- it's a digital
signal modulated in a certain way. So a book on wireless communications
would be a good place to start [1-3].
Having said that, there are some insightful papers from the sensor
networking community. Zhao, Govindan [4] is widely cited as identifying the
"gray region" where packet reception can vary widely. Zuniga, Krishnamchari
[5] provides an analytical model. Srinivasan, et al. [6] performed extensive
experiments with Telos/MicaZ motes.
Good luck,
