A Dynamic Reconfigurable Adaptive Software Architecture for Federate in HLA-based Simulation

As high level architecture (HLA) standard widely used in underwater warfare simulation applications, it is imperative that we should meet the need for the adaptation to the changing warfare requirements and improve development efficiency and reusability of simulation software, especially when developing a federate, known as a node in HLA-based distributed simulation. To address this problem, we present a dynamic reconfigurable adaptive software architecture for federate in this paper. The architecture has capability of self-adaptation to simulation requirements, and separates function realization from configuration control. It is composed of four layers, interface communication, requirement management, adaptation management and function realization. In this architecture, we partition the federate into several functional parts in terms of a definite granularity with Component-Based Software Development (CBSD) methodology. The architecture can adjust dynamically the configuration of federate to the new requirements while the simulation requirements change. Finally, we take a general sonar federate as an example to illustrate the presented architecture´s support for adaptation.
