Abstract: Along with the popularization of Internet applications, more and more software systems operate in an open environment, and need to perceive and adapt the change of environment. How to support the development of such complex software systems has become a major challenge to the current software engineering. We discussed the problem betwecn the adaptive system and its environment, and we abstracted software entity from adaptive system to Autonomous Agent We put forward the thought of software sensor dynamic association with the environment,given the design and implementation of software sensor. Unlike existing research, we regarded software sensor as a kind of special software Agent Finally, papers demonstrated the feasibility and validity of these ideas and techniques by case studies.

Key words: Environment, Self-adaptive Agent, Sense, Software sensor
