I presume you mean same statistical properties.
https://en.wikipedia.org/wiki/Small-world_network
explains the difference between random networks and many real sw networks.

Your real data should have connect and disconnect (start and stop) 
times.  The data below could represent a decay situation where all 
connections exist at time 0 and the time represents how long they last 
before breaking.  Or a much different growth situation where there are 
initially no connections and they slowly accumulate. Or some sort of 
steady situation.

etc. The small-world-network concept is a static, or perhaps snapshot 
concept.  Modeling link changes in a way that maintains the statistical 
properties is a harder problem.
