The Problem of Formation Adjustment in Aircraft Federate Development

In the HLA federates development, there are two types of object communication methods: (1) objects communication between federates are through RTI; (2) objects communication in one federate uses usual object-oriented method. But in some special circumstances, the object communication type may change dynamically. To solve this problem, we suggest four methods: (1) using interaction through RTI uniformly; (2) using ownership transformation; (3) partitioning federate so as we can use only one type of communication methods; (4) using framework based method. We analyze the feasibility of these methods and discuss the framework-based method in detail.
