Abstract
In a ubiquitous computing (ubicomp) environment, system components of different types, including hardware elements, software components, and network connections, must cooperate mutually to provide services that fulfill user requirements. Consequently, advanced and flexible characteristics of software that are specialized for a ubicomp environment are needed. This article presents a proposal of an agent-based middleware for a ubicomp environment comprising computers and home electric appliances. The middleware, called AMUSE, can take quality of service (QoS) in a ubicomp environment into consideration by coping not only with user context but also with the resource context, using agent-based computing technology. Herein, we describe the concept, design, and initial implementation of AMUSE. Simulation results of an experimental ubiquitous service using AMUSE demonstrate the effectiveness of our proposed scheme. Additionally, to confirm our scheme’s feasibility and effectiveness, we describe the initial implementation of a multimedia communication application based on AMUSE.
