A Review on Provisioning Quality of Service of Wireless Telemedicine for E-Health Services
In general, on-line medical consultation reduces time required for medical consultation induces
improvement in the quality and efficiency of healthcare services. All major types of current e-health applications such as ECG, X-ray, video, diagnosis images and other common applications have been included in the scope of the study. In addition, the provision of Quality of Service (QoS) for the application of specific healthcare services in e-health, the scheme of priority for e-health services and the support of QoS in wireless networks and techniques or methods for IEEE 802.11 to guarantee the provision of QoS has also been assessed.
In e-health, medical services in remote locations such as rural healthcare centers, ambulances, ships as well as
home healthcare services can be supported through the applications of e-health services such as medical
databases, electronic health records and the routing of text, audio, video and images. Given this, an adaptive
resource allocation for a wireless network with multiple service types and multiple priorities have been
proposed. For the provision of an acceptable QoS level to users of e-health services, prioritization is an
important criterion in a multi-traffic network. The requirement for QoS provisioning in wireless broadband
medical networks have paved the pathway for bandwidth requirements and the real-time or live transmission
of medical applications. From the study, good performance of the proposed scheme has been validated by the
results obtained. The proposed wireless network is capable of handling medical applications for both normal
and life-threatening conditions as characterized by the level of emergencies. In addition, the bandwidth
allocation and admission control algorithm for IEEE 802.16- based design specifically for wireless
telemedicine/e-health services have also been presented in the study. It has been concluded that under busy
traffic conditions, the proposed architecture can used as a feasible and reliable infrastructure network for
telemedicine
Ubiquitous Computing for Remote Cardiac Patient Monitoring: A Survey
New wireless technologies, such as wireless LAN and sensor networks, for telecardiology purposes give new possibilities for monitoring vital parameters with wearable biomedical sensors, and give patients the freedom to be mobile and still be under continuous monitoring and thereby better quality of patient care. This paper will detail the architecture and quality-of-service (QoS) characteristics in integrated wireless telecardiology platforms. It will also discuss the current promising hardware/software platforms for wireless cardiac monitoring. The design methodology and challenges are provided for realistic implementation

Provisioning Quality of Service of Wireless Telemedicine for E-Health Services: A Review
In general, on-line medical consultation reduces time required for medical consultation
and induces improvement in the quality and efficiency of healthcare services. The scope of study includes several key features of present day e-health applications such as
X-ray, ECG, video, diagnosis images and other common applications. Moreover, the provision of Quality of Service (QoS) in terms of specific medical care services in e-health, the priority set for e-health services and the support of QoS in wireless networks and techniques
or methods aimed at IEEE 802.11 to secure the provision of QoS has been assessed as
well. In e-health, medical services in remote places which include rustic healthcare centres,
ships, ambulances and home healthcare services can be supported through the applications of e-health services such as medical databases, electronic health data and the transferring of text, video, sound and images. Given this, a proposal has been made for a multiple service
wireless networking with multiple sets of priorities. In relation to the terms of an acceptable QoS level by the customers of e-health services, prioritization is an important criterion in a multi-traffic network. The requirement for QoS in medical networking of wireless broadband has paved the way for bandwidth prerequisites and the live transmission or real-time medical
applications. The proposed wireless network is capable of handling medical applications for both normal and life-threatening conditions as characterized by the level of emergencies. In addition, the allocation of bandwidth and the system that controls admittance designed based
on IEEE 802.16 especially for e-health services or wireless telemedicine will be discussed in
this study. It has been concluded that under busy traffic conditions, the proposed architecture
can used as a feasible and reliable infrastructure network for telemedicine
A comprehensive survey of wireless body area networks on PHY, MAC, and network layers solutions
Recent advances in microelectronics and integrated circuits, system-on-chip design, wireless communication and intelligent low-power sensors have allowed the realization of a Wireless Body Area Network (WBAN). A WBAN is a collection of low-power, miniaturized, invasive/non-invasive lightweight wireless sensor nodes that monitor the human body functions and the surrounding environment. In addition, it supports a number of innovative and interesting applications such as ubiquitous healthcare, entertainment, interactive gaming, and military applications. In this paper, the fundamental mechanisms of WBAN including architecture and topology, wireless implant communication, low-power Medium Access Control (MAC) and routing protocols are reviewed. A comprehensive study of the proposed technologies for WBAN at Physical (PHY), MAC, and Network layers is presented and many useful solutions are discussed for each layer. Finally, numerous WBAN applications are highlighted
Stream bundle management layer for optimum management of co-existing telemedicine traffic streams under varying channel conditions in heterogeneous networks.
Heterogeneous networks facilitate easy and cost-effective penetration of medical advice in both rural and urban areas. However, disparate characteristics of different wireless networks lead to noticeable variations in network conditions when users roam among them e.g. during vertical handovers. Telemedicine traffic consists of a variety of real-time and non real-time traffic streams, each with a different set of Quality of Service requirements. This paper discusses the challenges and issues involved in the successful adaptation of heterogeneous networks by wireless telemedicine applications. We propose the development of a Smart Bundle Management (SBM) Layer for optimally managing co-existing traffic streams under varying channel conditions in a heterogeneous network. The SBM Layer acts as an interface between the applications and the underlying layers for maintaining a fair sharing of channel resources. Internal priority management algorithms are explained using Coloured Petri nets. This paper lays the foundation for the development of strategies for efficient management of co-existing traffic streams across varying channel conditions
