The Implementation of Adaptive User Interface Migration Based on Ubiquitous Mobile Agents

MA(Mobile Agent) is active, autonomous, and self-replicable software object containing both computational logic and state information. One advantage of using MA paradigm instead of conventional message passing paradigm is that it can reduce communication traffic among the computing devices in the system. Also, the MA paradigm supports asynchronous interaction of computing devices, enabling more efficient system services. In order to adopt the MA paradigm into the ubiquitous computing technologies, it is necessary to develop a lightweight middleware platform, called MAP(Mobile Agent Platform), that supports agent migration and install it in various devices such as PDAs, hand-held devices, and digital appliances. In this paper, we propose our lightweight MAP, named KAgentPlatform, that is developed based on J2ME for ubiquitous environments. Especially, we describe our design and implementation of the KAgentPlatform, and show the experiments of adaptive UI migration based on ubiquitous mobile agents.
