There are different statistics collected by OPS during a simulation. These statistics are available at the Node level and at the Network level. Statistics are initiated from different protocol layers of a node model. There are two types of statistics collected.
-
Vector statistics - These are the continuous statistics that are collected. These results can be plotted as graphs.
-
Scalar statistics - These are the measures of dispersion type statistics collected. In OPS, we only collect the final value of a scalar statistic.
Information about each of these statistics are given below.
The table below lists the statistics generated from the application layer.
