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,

As for specific propagation models, I focus on outdoor networks. Most often
I read papers that reference either the log-normal shadowing model or the
two-ray/two-slope model. The paper below references those models and
provides plenty of empirical data.
