-OverSim uses churn generators for simulating non-static networks. The different churn generators simulate different user behaviour and can be configured individually. Note: all churn generators use an "init phase" where nodes will be added to the network until targetOverlayTerminalNum is reached: On average every "**.initPhaseCreationInterval" seconds, one node will be added; measurements will start after all nodes have joined the network.

    * Node behaviour: On creation of a node, his lifetime will be drawn randomly from a given probability function. When this time is reached, the node is removed. A new node will be created after a ''dead time'' drawn from the same probability function.
    * Parameters:
-      * lifetimeMean: The mean lifetime.
+      * lifetimeMean: The mean lifetime (in sec).
       * lifetimeDistName: The function used for drawing the lifetimes (default: weibull)
 * '''!ParetoChurn'''
    * Node behaviour: Similar to !LifetimeChurn, a node's lifetime is drawn on creation. However, this is done in a two-stepped process. For details, please read ''Yao, Z.; Leonard, D.; Wang, X. & Loguinov, D. "Modeling Heterogeneous User Churn and Local Resilience of Unstructured P2P Networks" Proceedings of the 2006 14th IEEE International Conference on Network Protocols, 2006. ICNP '06. 2006, pp. 32--41''
    * Parameters:
-      * lifetimeMean: The mean lifetime.
-      * deadtimeMean: The mean deadtime.
+      * lifetimeMean: The mean lifetime (in sec).
+      * deadtimeMean: The mean deadtime (in sec).
    * Notes: This churn generator results in heavy tailed session times similar to empirical results from P2P filesharing networks or MMOGs.
 * '''!RandomChurn'''
