A Middleware Approach to Intelligent Emergency Health Care Messaging Using Wireless Networks

Use of emergency messaging system is a key to effective communication in healthcare applications by emergency responders during calamity. Evolving high speed wireless networks facilitate to connect emergency responders to an emergency electronic routing directory, data sharing systems, handling real time emergency information among multiple services. In this paper we analyze the performance of a middleware architecture that implements a prioritized context-centric loosely coupled messaging mechanism to support Emergency Medical Services (EMS). The context-centric messaging is an application layer messaging mechanism that provides reliable and secure messaging within the middleware architecture for distributed data sharing and location identification. RealTime testing using CDMA 1XRTT network between a data capturing tool from an ambulance and a database server was performed to analyse the messaging mechanism efficiency. The test results based on round trip time and bandwidth are discussed in this paper.
