Improving Quality of Video Streaming over Mobile Networks to Leverage Healthcare Services

Abstract: Advancements in mobile technologies paved way for transmission of multimedia over such networks. Wireless devices and wearable devices are widely used in healthcare infrastructure. Due to errors in wireless channel video streaming quality over wireless devices is deteriorated. In a healthcare unit physicians need to know vital signs of patients in real time. Physician can diagnose the problem of patient before patient reaches hospital with the innovative technologies that seamlessly integrate mobile devices and healthcare network in hospital. All stakeholders of healthcare unit are connected with the network. The problem to be addressed here is to ensure that video pertaining to patient?s ultrasound or any such useful thing is transferred healthcare server with acceptable quality. Thus doctors can have diagnosis and provide real time response to the needs of patients who are in need of emergency health services. In this paper we focus on using error concealment technique to improve quality of video streaming based on the region of interest specified by doctor. Thus better communication to physicians is made possible and the utility of the healthcare infrastructure is appreciated. To achieve this cross-layer design is made and implemented using NS2 simulations. The experimental results revealed that the proposed solution is useful to improve quality of services in healthcare unit.
