Mobile Information Systems in a Hospital Organization Setting

The emerging of wireless computing motivates radical changes of how information is obtained. Our paper discusses a practical realisation of an application using push and pull based mechanism in a wireless ad-hoc environment. We use a hospital information system as a case study scenario for our proposed application. The pull mechanism is initiated from doctors as mobile client to retrieve and update patient records in the central database server. The push mechanism is initiated from the server without a specific request from the doctors. The application of push mechanism includes sending a message from central server to a specific doctor, and multicasting a global message to all doctors connected to the server application. The global message can be disabled by each doctor to perform selective recipients.
