Prototype Implementation 2003-05-22 TeleMedng Communication System Design 2003

Implementation Approaches Transmission of data Java Application Approach (custom solution) Not scalable, Time consuming Inefficient way of data transmission Information Bus Approach (IBM WebSphere MQ) Guaranteed delivery and prevention of duplicates Forwarding ability at a later time Database Oriented Approach (oracle 9i) Provides Application Server and Advanced Queuing facilities Message propagation to a specified Queue Guaranteed delivery and exception handling Provides prioritizing between messages among others 2003-05-22 TeleMedng Communication System Design 2003

Advantages of MQ Approach Very scalable Can handle thousands of clients Easy to maintain Saves time and money Future-proof approach Lower maintenance costs Technology already familiar to the staff of the Hospital Products already licensed and ready for use Existing commercial components can be used Easier programming Easier code testing 2003-05-22 TeleMedng Communication System Design 2003

Communication System Design 2003 Future Work Investigate the use of other Message Queue systems Extend with full user interfaces on both client and server side Implement the platform on a residential gateway or other suitable hardware Implement teleconferencing between patients and the hospital Investigate technology for redundancy in communication and data storage Test the platform with real patients Evaluate the test and the patients’ perception of it 2003-05-22 TeleMedng Communication System Design 2003

Communication System Design 2003 Summary & Conclusions Telemedicine gives benefits and save money Large cost savings when system used in large scale Concept of the designed platform is proved Interesting future opportunities to extend the system Telemedicine expansion has just begun… 2003-05-22 TeleMedng Communication System Design 2003
