Research On Software Self-Configuration Method Based On Context Awareness

In order to adapt to the open internet environment and the changes of users'needs, the software system requires the ability to constantly adjust itself to suit the internal and external environmental changes. In this paper, the concept of self-configuration of the control loop is proposed to achieve self-configuration, which complete adaptation to the changes of environ-mental. On the basis, SOA-based self-configuration framework is designed to achieve feature-s of the self-awareness for computing unit, and then a generic self-configuration method of the software system is proposed from the service perspective, and experiments show that the method has a good quality of service support capabilities.Firstly, we analyze the concept of self-configuration and the basic principles of technolo-gy. The concept of self-configuration unit is proposed and to be designed. Furthermore, the working mechanisms and the core architecture of self-configuration are analyzed. Therefore, we built the infrastructure facilities of self-configuration software system and framework with SOA technology.Secondly, from a service-oriented perspective, a general method of self-configuration is presented to solve the self-configuration problems both in macro-level and micro-level. Then the related issues of service matching and service consistency is studied, and we proposed an algorithm of tiered service matching based on semantic and service loading algorithm to solve this problem in a dynamic, open, self-configuration computing environment.At last, after the analysis of the body and software framework of self-configuration, we also do the experiment to verify the capability that is improving quality of service by the me-thod. The results show that the design of SOA-based self-configuration system in the distribu-ted computing environment has the ability of self-deployment and also have the function of the improving the quality of service function.
