TITLE: Models for graphs representing real-life networks
QUESTION [13 upvotes]: I am interested in basic models of graphs (stochastic or deterministic) that are offered for real-life networks (like social networks, the Internet, neuron networks).
I will be thankful for answers that will describe the actual model and not just link to some reference. (Such links can be useful in comments.)

REPLY [3 votes]: There are different models for terrorist or other criminal networks. I can only give references.

This model was actually used by the head of Jamaica's National Intelligence Bureau.
