Medical Quality of Service for Wireless Ultrasound Streaming in Robotic Tele-Ultrasonography System

Abstract

presented in this paper. Abstract Mobile healthcare (m-health) is an emerging Generally providing end-to-end quality-of-service (QoS) to research area. There are two critical issues facing successful real time video delivery in wireless networks is becoming an deployment of m-health applications from the wireless increasingly important application requirement in mobile communications perspectives. First, wireless connectivity issues communications and multimedia research. Supporting robust and mobility requirements of real-time bandwidth demanding mhealth applications. Second, are the Quality of Service (QoS) video commations ov wi netors is ansgificant issues from the healthcare perspective and their required levels problem, primarily because of two factors: low bandwidth and to guarantee robust and clinically acceptable healthcare services. the time varying error characteristics of the transmission In this paper, we consider the concept of medical QoS (m-QoS) channel. Therefore, adaptation scheme has to be applied in issues for typical bandwidth demanding m-health application order to overcome these challenges. (tele-ultrasound streaming) in 3G environments. Specifically we For bandwidth demanding i-health applications, we adopt introduce this new concept of m-QoS that provide a sub-category of quality of services from the m-health perspective. To validate here a wireless robotic tele-ultrasonography system OTELO this concept we also propose a new optimal rate control policy as an example to validate the concept presented in this paper based on Q-learning approach to deliver the ultrasound images [2]. OTELO can be considered as bandwidth-demanding over 3G environment. medical data traffic system with different m-QoS requirements.

H.265 Codec over 4G Networks for Telemedicine System Application

“…The reason for this is the lack of a video codec that can support both high-quality video streaming together with relatively low bandwidths available for the purpose of streaming it over wireless networks. Telemedicine systems should be able to stream videos similar in terms of their quality [8] to the video that is used in hospital examination screen from the resolutions and frame rates prospective Therefore, this paper recommends H.265 [10] as a replacement to other video types used in telemedicine systems because of its features and suitability for 4G wireless networks such as WiMAX and LTE networks. WiMAX has significant deployment in areas without a limited existing 3G cellular phone network, such as India, while LTE has been recently rolled out in the U.S.A and parts of western Europe.…”

Provisioning of medical quality of services for HSDPA and mobile WiMAX in healthcare applications

“…These issues become paramount in bandwidth demanding medical applications such as real-time ultrasound video streaming systems that 4G systems advocate. The concept of m-QoS is defined as the 'Augmented requirements of critical mobile health care applications with respect to the traditional wireless Quality of Service requirements' [2,3]. In general the provision of end-to-end medical quality-of-service (m-QoS) will become an important factor in future WiMAX and HSDPA/HSUPA network systems and their acceptability for bandwidth demanding mobile healthcare applications.…”
