A wireless body area network of intelligent motion sensors for computer assisted physical rehabilitation
BACKGROUND: Recent technological advances in integrated circuits, wireless communications, and physiological sensing allow miniature, lightweight, ultra-low power, intelligent monitoring devices. A number of these devices can be integrated into a Wireless Body Area Network (WBAN), a new enabling technology for health monitoring. METHODS: Using off-the-shelf wireless sensors we designed a prototype WBAN which features a standard ZigBee compliant radio and a common set of physiological, kinetic, and environmental sensors. RESULTS: We introduce a multi-tier telemedicine system and describe how we optimized our prototype WBAN implementation for computer-assisted physical rehabilitation applications and ambulatory monitoring. The system performs real-time analysis of sensors' data, provides guidance and feedback to the user, and can generate warnings based on the user's state, level of activity, and environmental conditions. In addition, all recorded information can be transferred to medical servers via the Internet and seamlessly integrated into the user's electronic medical record and research databases. CONCLUSION: WBANs promise inexpensive, unobtrusive, and unsupervised ambulatory monitoring during normal daily activities for prolonged periods of time. To make this technology ubiquitous and affordable, a number of challenging issues should be resolved, such as system design, configuration and customization, seamless integration, standardization, further utilization of common off-the-shelf components, security and privacy, and social issues

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
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
Emergency Prenatal Telemonitoring System in Wireless Mesh Network
Telemedicine promises a great opportunity for health care service improvement. However, it has several issues for its implementation in certain area. They include communication service quality, infrastructure and operational cost. Since Wireless Mesh Network (WMN) is designed to reduce the infrastructure cost and operational cost, an investigation of network performance for implementation of telemedicine is required. In this paper, a simulation to investigate the wireless mesh network quality of service.  Using network simulator 2, The QoS performance analysis was performed in different routing protocol scenarios of proposed system. It showed that OLSR protocol for Mesh Network maintained the time transfer of the EPT data. The field testing of the proposed system to measure the distance with various time has already been done.  The infrastructure has been also implemented using low cost 5.8 GHz transceiver for backhauls and low cost 2.4 GHz transceiver for clients. Test result shows that the low cost telemedicine system is able to do real time communication between patient and medical staff with medical data rate up to 2 Mbps. It shows that telemonitoring system using wireless mesh network can give a low cost application in emergency time with acceptable medical data transfer quality.
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
Logic-centred architecture for ubiquitous health monitoring
One of the key points to maintain and boost research and development in the area of smart wearable systems (SWS) is the development of integrated architectures for intelligent services, as well as wearable systems and devices for health and wellness management. This paper presents such a generic architecture for\ud
multiparametric, intelligent and ubiquitous wireless sensing platforms. It is a transparent, smartphone-based sensing framework\ud
with customizable wireless interfaces and plugânâplay capability to easily interconnect third party sensor devices. It caters to wireless\ud
body, personal, and near-me area networks. A pivotal part of the platform is the integrated inference engine/runtime environment\ud
that allows the mobile device to serve as a user-adaptable personal health assistant. The novelty of this system lays in a rapid visual\ud
development and remote deployment model. The complementary visual InferenceEngineEditor that comes with the package enables\ud
artificial intelligence specialists, alongside with medical experts, to build data processing models by assembling different components\ud
and instantly deploying them (remotely) on patient mobile devices. In this paper, the new logic-centered software architecture for ubiquitous health monitoring applications is described, followed by a\ud
discussion as to how it helps to shift focus from software and hardware development, to medical and health process-centered design of new SWS applications
