SqliteOutputManager class
Output manager that stores data in a database.
This output manager is done to save the output of the examples cttc-coexistence-indoor-scenario.cc and cttc-nr-wigig-interference.cc.
The class create a SQLite database which contains the following tables:
- sinr_results, which contains the SINR of every packet in the network
- mac_data_tx_failed which contains the count of MAC data transmission failed
- channel_occupancy which contains the time of channel occupancy divided per technology
- collision, which despite the name contains the number of simultaneous transmission per technology
- e2e, which contains the e2e IP statistics of the flow.
The data is saved through a call to each virtual method, that saves the inputs in the database. For an usage example, please look into the provided examples.
Base classes
- class OutputManager
- The OutputManager interface for storing the simulation data.
Constructors, destructors, conversion operators
