Medical body area networks will employ a range of implantable and body worn devices to support a wide range of applications with diverse QoS requirements. The IEEE 802.15.6 working group is developing a communications standard for low power devices operating on, in and around the body and medical devices are a key application area of the standard. The(More)
Wireless Body Area Networks (BANs) have the ability of gathering and sending on-body measurements to a terminal. Autonomous nodes are deployed on the body to monitor vital signs and environmental parameters. The IEEE 802.15.6 standard mainly specifies physical and medium access for BANs. Routing is discussed as part of the link layer and multihop is not(More)
The emerging area of body area networks (BAN) imposes challenging requirements on hardware and software to achieve the desired lifetimes for certain devices such as long term medical implants. In this paper, we propose a novel approach to the measurement and characterisation of the energy consumption of BAN devices. The approach uses a low cost energy(More)
In this paper, we study the problem of routing, bandwidth and flow assignment in Wireless Body Area Networks (BANs). Our solution considers BAN for real-time data streaming applications, where the real-time nature of data streams is of critical importance for providing a useful and efficient sensorial feedback for the user while system lifetime should be(More)
In Body Area Networks (BANs), quality of service is needed to provide reliable data communication over prioritized data streams coming from energy constrained sensors attached to, or possibly implanted in, patients. In this work, we focus on BAN for real-time data streaming applications, where the real-time nature of data streams is of critical importance(More)
BACKGROUND Direct/ measurement of work activities is costly, so researchers need to distribute resources efficiently to elucidate the relationships between exposures and back injury. METHODS This study used data from full-shift electromyography (EMG; N=133) to develop three exposure metrics: mean, 90th percentile and cumulative EMG. For each metric, the(More)
The number of Soft-IP vendors and designsbecoming available on the global market is growing at a phenomenal rate. The current practice of evaluating Soft IPs using their specification is a time consuming manual process. A specification document is primarily written in English, which serves as a common language for internal product development teams as well(More)
Unreliability is an inherent property of wireless links. In opportunistic networks, these intermittent links are exploited, instead of mitigated, by temporal and/or spatial diversities in order to improve the network performance such as energy efficiency, delay, throughput and so on. Simulation is always an important method for the research in this(More)
Occupational injury research depends on the ability to accurately assess workplace exposures for large numbers of workers. This study used mixed modeling to identify observed and self-reported predictors of mean, 90th percentile, and cumulative low back muscle activity to help researchers efficiently assess physical exposures in epidemiological studies.(More)
