A Joint Simulation Framework based on OPNET External System Module for Tactical Data Links

A novel joint simulation framework based on OPNET External System Module (ESM) for tactical data links is proposed. It uses the extension interface to organically combine the data link node model of the OPNET simulation platform with ESM based on C/C++, and drives the time rolling and event execution of the OPNET simulation platform and ESM through the execution controller. Then, the SPMA protocol of TTNT waveform is taken as an example to illustrate the design and implementation of the key links in the joint simulation framework, such as expansion interface, node model, ESM, etc. Finally, a typical network scene are set to comprehensively evaluate the rate control of SPMA and other key functional indicators, which verifies the effectiveness of the proposed joint simulation framework.
