This study analyzes the reasons for the low reusability of current HLA federates and extends the RTI framework to improve the federate reusability. The extension framework is implemented by adding a self-adapting middle mapping layer to the standard HLA/RTI framework to manage the mapping between the fixed SOM of the federate and the FOM of the federation for various reuse scenarios. The key to the mapping layer is the construction of the mapping model. This paper presents a meta-model for the message mapping operator which can dynamically construct the mapping model. The extension of the RTI framework with the self-adapting middle mapping layer effectively promotes the federate reusability, so a former federate can join a new federation and run correctly. Tests show that this extension framework is feasible and effective.
