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,
Ken
