Utilising push and pull mechanism in wireless e-health environment

Abstract

The emerging of wireless computing motivates radical changes of how information is derived. Our paper concerns with developing push and pull based application in wireless environment. We use a simplified e-health (hospital) context to demonstrate some effective uses of pull-based and push-based mechanisms. The pull mechanism involves information retrieval from a database, and update information in the database. The push mechanism is classified into three scenarios, (i) aperiodic push, (ii) periodic push - global recipients and (iii) periodic push - selective recipients.
