Abstract

The invention discloses a half-practicality network simulation platform of aviation Ad-Hoc network. The platform comprises a mapping management unit processing module and a communication channel module. The mapping management unit processing module is used for dynamically establishing and destroying mapping nodes according to requirements of practicality nodes. The communication channel module comprises a port processing module. The port processing module is used for sending data of the practicality nodes to the mapping nodes via data interactive channels and packaging and sending corresponding data of the mapping nodes to corresponding virtual nodes. After receiving the data of the virtual nodes, the mapping nodes send the data to corresponding practicality nodes via the data interactive channel. According to the invention, mapping relations are dynamically initiated via the practicality nodes and mapping mechanism is finished via the simulation platform, so flexibility of verification of the half-practicality network simulation platform is improved.
