Development of event manager and its application in jini environment

Abstract

Ubiquitous computing services have to adapt to the context information. These services have to communicate with each other through fixed network or ad-hoc, it is the ubiquitous middleware to be able to help those services. With regard to the adaptation of middleware's components, context manager and event manager are required. Recently there is a widely used middleware, Jini, but it is distributed without the event manager services. Therefore we implement the event manages which can manage events in Jini environments, and describe ubiquitous computing applications running environment using our event management system. Our event manager is implemented by modifying Javaspaces. © IFIF International Federation for Information Processing 2005.
