Work-in-Progress: An OMNET++ Simulation Model for IMA Systems

Integrated Modular Avionics (IMA) architecture is designed to integrate units with different applications on a single hardware platform. It has many configuration parameters and design options that affect system and network performance, so estimating the system's behavior can only be accessible if the complete system is executed. Therefore, implementing an avionic system in a simulation environment simplifies finding the optimum system settings. Moreover, this enables engineers to build system prototypes without performing any physical effort. The contribution of this paper is to develop a simulation model of an IMA system in the OMNET++ simulator, to evaluate the network performance of IMA systems. The proposed model is validated using an example scenario with application delay and packet loss ratio metrics.
