You could take a look at the CHP library: 
http://www.cs.kent.ac.uk/projects/ofa/chp/. The library is influenced by 
the CSP calculus, which is used to reason about systems of communicating 
processes. Using this, you could model each node of your network as a 
CHP process which communicates with the other nodes over channels. All 
the communication is synchronous, and the theory behind it is pretty 
solid: http://www.usingcsp.com/
