Performance Analysis of Medical Video Streaming over Mobile WiMAX
ABSTRACT Wireless medical ultrasound streaming is considered one of the emerging application within the broadband mobile healthcare domain. These applications are considered as bandwidth demanding services that required high data rates with acceptable diagnostic quality of the transmitted medical images. In this paper, we present the performance analysis of a medical ultrasound video streaming acquired via special robotic ultrasonography system over emulated WiMAX wireless network. The experimental set-up of this application is described together with the performance of the relevant medical quality of service (m-QoS) metrics.

ABSTRACT: The emerging 4G (fourth generation) networks featuring wider coverage, higher transmission bandwidth and easier deployment have a desirable potential to serve ubiquitous and pervasive multimedia applications in creating new user-centric communication services. However, the practical implementation of 4G network to demonstrate such potential, especially for delivering real-time and high-quality video services, is scarce. This paper therefore provides the design and implementation of a future Internet live TV system over 4G networks to achieve cost-effectiveness, instead of using expensive satellite news gathering (SNG) vehicle and costly satellite transmissions in traditional TV stations. To effectively provide live TV services, we apply not only the hybrid duplex modes but also the port-based VLAN on the deployed networks for maximizing bandwidth, minimizing signal interference, and guaranteeing QoS of differentiated services. Performance metrics are applied to demonstrate that the proposed solution is cost-effective and is feasible for live TV services in future Internet.Telecommunication Systems 11/2013; DOI:10.1007/s11235-013-9728-8 · 1.16 Impact Factor
