Abstract

Application reconfiguration provides a powerful mechanism to adapt component-based distributed applications for changed environmental conditions. In this paper, we propose an effective environment adaptive application reconfiguration (EAAR) mechanism based on the feedback-loop concept of the control theory. Based on this mechanism, a pull-based paradigm is introduced to represent the sensing-judging-acting process in sensor networks. We utilize rule-based knowledge to analyze the change of environment, thus perform self-adaptive application reconfiguration efficiently. To demonstrate how EAAR mechanism works, we simulated a scenario of reconfiguring applications in sensor networks.
