유비쿼터스 환경에서의 이동코드 지원 시스템

다국어 초록 (Multilingual Abstract)

There is an increasing concern for sensor network, as an infrastructure technology to construct ubiquitous computing environment in the future. A sensor network has some inherent features such as largely deployment and scare resources. Also, it is not possible to provide an additional and/or future management scheme after a sensor network installed in the field. Therefore, the code mobility technology, in which carries an execution code in the message, is getting important in order to dynamically execute various applications in ubiquitous network. This thesis deals with the mobile code system to achieve a code mobility. It starts with defining a mobile code message to deliver an execution code and designing a system to executes a partial portion of application code in the message, and then the current node passes a new mobile code message, which additionally includes the state information of last execution node, to the next nodes. An application scenario has been implemented using the mobile code system, in order to show its feasibility and effectiveness in a ubiquitous network. It is expected our works to provide a technical basement for ubiquitous network's applicability
