Transcutaneous Energy Transfer (TET) is a promising solution to operate implantable mechanical blood pumps such as Left Ventricular Assist Devices (LVAD) without the need for a percutaneous driveline. In order to control the power flow of the wireless energy transfer system and in order to transmit sensor data, a wireless communication channel is needed. This paper describes the design of an implantable...
The time-variant nature of the Wireless Body Area Networks (WBANs) channels turns unclear if the application's Quality of Service (QoS) requirements can be guaranteed. This paper provides an on-body signal propagation statistical characterization, following a scenario-based approach, and a communication performance evaluation of several wearable devices, which are attached to a Personal Protective...
This paper introduces new functionalities for industrial safety applications using the wireless infrastructure of the IEEE 802.11 standard. The new amendments (n/ac/ad) for the 2.4, 5, and 60-GHz-band support additional high data rate modes, for e.g. video applications and device-to-device (D2D) communication. The huge bandwidth in the 60-GHz-band enables precise localization. However, Listen-Before-Talk...
Industrial Internet of things (IIoTs) relies on different devices working together, gathering and sharing data using multiple communication protocols. This heterogeneity becomes a hindrance in the development of architectures that can support applications operating independently of the underlying protocols. Therefore in this paper, we proposed a modular and scalable architecture based on lightweight...
Studies show that the poor hand hygiene practices in public health institutions such as hospitals, clinics, schools and nursing homes is the most likely cause of the spread of various bacterial diseases. Proper hand hygiene is the single biggest defense against spread of diseases and therefore the caregivers' compliance with hand hygiene is one of the most effective tools in preventing Healthcare...
In this paper, we introduce a novel performance analysis of the η-μ generalized radio fading channels with integer value of the μ fading parameter, i.e. with even number of multipath clusters. This fading model includes other fading models as special cases such as the Nakagami-rn, the Hoyt, and the Rayleigh. We obtain novel unified and generic simple closed-form expressions for the average bit error...
This paper proposes a reconfigurable scheme of wireless power transmission in fully-enclosed box. The proposed scheme includes one transmitting element and multiple parasitic elements. Field distribution inside the box is reconfigured by switching the parasitic elements' termination between open and short, with the aim of delivering wireless power efficiently to a receiver whose location is not fixed...
An 8×8 (64) Internet of Things (IoT) wind farm platform is built using miniaturized wind turbines with wireless connectivity. The farm is being deployed on the south east coast of Ireland to remotely collect data for offline evaluation of a data driven wind turbine power output model and study aerodynamic interactions between turbines within the farm. The cluster is build such that a range of different...
A real-time irrigation scheduling system (ISS) for greenhouses has been developed in compliance with the ISO/IEC/IEEE 21451 standard. The developed system is capable of displaying greenhouse and irrigation scheduling parameters. Irrigation can wirelessly be automated by the sensor node by activating irrigation based on sensor values and predefined irrigation parameters. A low power sensor node was...
With advancement in the concept of internet of things (IoT), many industrial applications today have migrated from wired to wireless communication protocols. The major requirements of industrial devices utilizing wireless technologies include high performance reliability similar to wired network, and longevity in terms of battery life. Wireless field devices that run on battery should be able to operate...
With the growing interest in adoption of wireless technologies in industrial automation and the continuous search for new revenue streams new players are entering the arena in order to make their business grow further. One of the emerging wireless technologies aiming to support industrial automation applications is 5G, targeting anything from extreme throughput (> 10 Gbit/s) to extreme low latency...
This paper proposes a fast and low-complexity retransmission scheme for Industrial WLAN system. The proposed scheme exploits the frequency diversity and employs channel selectivity in order to achieve high-reliability and low-latency communication. The channel selectivity is carried out instantly by re-scheduling sub-carrier allocation during OFDM transmission in order to obtain diversity gain. Evaluation...
