Enhancement of Emergency Telemedicine Diagnosis Using 3G+ Mobile Systems

摘要

Mobile telemedicine is used in cases of emergency when an ambulance needs to communicate with an expert doctor present at a distant location. With the present day telemedicine systems lacking a framework that can handle all the types of data like real time video, audio and heavy data like Magnetic Resonance Image (MRI), X-ray scans, live cardiograms, and other types of medical data, it becomes necessary to design a telemedicine system that can tackle all the problems and provide a robust telemedicine system. This paper focuses on providing an efficient mobile wireless telemedicine system using 3G+ mobile systems based on High Speed Downlink Packet Access (HSDPA) technology. The telemedicine system can handle real time audio, video streaming, interactive data and background traffic which are essential data traffic involved in a telemedicine system. The latency, jitter associated with the network is reduced without affecting the throughput by analyzing the packet scheduler available at the network layer of the UMTS-HSDPA network and various packet scheduling algorithms are tested. The mobile telemedicine system along with real time channel conditions and background traffic has been simulated in QualNet Developer Network Simulator.
