This allows a simple wireless architecture to be realized with low cost and power consumption. However, network congestion/failure can create potential issues in terms of reliability of data transfer, quality-of-service (QOS) and data throughput for the sensor. These issues can be especially critical in healthcare monitoring applications where data availability and integrity is crucial. The addition of more than one radio has the potential to address some of the above issues. For example, multi-radio implementations can allow access to more than one network, providing increased coverage and data processing as well as improved interoperability between networks. A small number of multi-radio wireless sensor solutions exist at present but require the use of more than one radio transceiver devices to achieve multi-band operation. This paper presents the design of a novel prototype multi-radio hardware platform that uses a single radio transceiver. The proposed design allows multiband operation in the 433/868MHz ISM bands. Its low complexity, power consumption and small form factor, make it suitable for a wide range of BSN applications. Rights

QoS in Body Area Networks

“…The miniaturization of sensors and sensor motes play a key role in the development of wearable systems. Researchers in academia and industries are working in parallel on miniaturization and accuracy of wearable sensors and sensor motes [Hadjidj et al 2012;Patel et al 2012b;Crosby et al 2012;Buckley et al 2012;HERZOG 2013;Honeywell 2014;Peiris 2013]. The wearable photoplethysmograph ring (WPPGR) biomedical sensor developed in [Yang and Rhee 2000] improves wearability.…”

Optimizing Joint Data and Power Transfer in Energy Harvesting Multiuser Wireless Networks

“…We start by the case where the BS powers the devices using dedicated subcarriers signals. Note that this scenario is appropriate for devices with limited hardware capabilities [32][33][34] typically used for health and fitness (body sensor devices) or industrial IoTs applications. Hardware restrictions limit devices to only tune and communicate over a small number of channels (e.g., the N subcarriers/channels assigned to each user), but not over a large number of channels to cover all the K × N channels used by the BS (as in the second system setup presented in Section IV).…”
