MongoDB Synchronization

My topology compose of one server machine (primary) with 20 node machine. (secondary) 

Each node are collecting data the are stored in the DB (Primary)

Occasionally one of nodes is disconnected (Wireless problem,...) but continues to collect data  for few hours, and after a period of time the node will be reconnected (back in range)

In this case I got two primary, what behavior should I expected?

I am looking look for a behavior that the node(That has been connected) will become secondary.

Any suggestion?



I'm afraid I'm not clear on your topology.

What is a 20 node machine that you describe as secondary?
