Representation of the Environment and Dynamic Perception in Agent-Based Software Evolution

As the Internet become mainstream software system environment, software systems shift from closed, static and controllable to open, dynamic and difficult to control. The changes in the environment are unpredictable; it is major challenge for software system research to ensure that the software systems can deal with dynamic environment and change themselves appropriately. In this paper, according to the Multi-Agent environment, we divide environmental perception mechanism into three parts: by defining the environment, the composition problems in Multi-Agent Systems environment are solved; by designing method by which dynamic environmental data is generated and changes, we propose a dynamic environmental perception model based on the "publish / subscribe" model; by customized rules, the system can change itself in the environment according to the appropriate action to achieve the entire software adaptive process. Finally, we present examples to verify the feasibility and effectiveness of the theory.
