Implementation of mobile collaboration application service in u-Hospital environments

In this paper, we suggest a mobile collaboration application service based on u-Hospital environments. The application service implements based mobile collaboration framework for Hospital work in ubiquitous environments. The mobile collaboration framework is using the distributed object group framework components such as group manager, security, information repository, dynamic binder objects. It is used to application service for interaction of the mobile devices. The u-hospital environment dived into three part entities: sensors, mobile devices and a hospital server. The information using collaboration application is arranged according to the dynamic access control model for context awareness. For the real-time process, we adopted the TMO(Time triggered Message-triggered Object) scheme and TMOSM(TMO Support Middleware) into the development environment for the hospital application service. Finally, we show the successful execution of our application service on our mobile collaboration framework using GUI screen capture according to various contexts: time, location, roles and etc.
