OpenThread Network Simulator 2 (OTNS2) simulates Thread networks using OpenThread POSIX instances and provides visualization and management of those simulated networks.
Note: this is a fork of the OpenThread OTNS project, made by IoTconsultancy.nl. It offers additional features including:
- Support for more accurate RF simulation of OpenThread nodes. This uses the OpenThread platform
ot-rfsim, which specifically supports RF simulation, for OT nodes. This C code is included. - Selectable radio (RF propagation) models with tunable RF parameters.
- Tunable radio parameters on each individual OT node. For example, CSL parameters or Rx sensitivity.
- Control of logging display from OT-node, using
logandwatchCLI commands. Logging to file per OT-node. The logging output can include all enabled OT-node log items. - Detailed logging options for RF operations (at log-level 'trace') performed in the simulated radio, at 1 us resolution.
- Animations with duration scaled to the actual time duration of a packet in flight (at low simulation speed only).
- Support for easily adding various node types (1.1, 1.2, 1.3, 1.3.1, Border Router)
- New graphical displays for overall node type statistics, and energy usage (beta - contribution by Vinggui).
- Extensive set of Python scripts for unit testing, examples, and case studies.
- Various UI look & feel improvements.
