“…Verification and validation were also discussed in combination with robustness and security concerns. The robustness of IoMT systems has been explored for numerous applications, such as power optimization and packet scheduling mechanisms for BANs [84], the development of an analysis framework allowing the improvement of IoMT interoperability [29], and analysis of the robustness of a MAC protocol for networked devices [85]. Some global reliability and safety framework have also been developed [56].…”

The Internet of Medical Things designates the interconnection of communication-enabled medical-grade devices and their integration to wider-scale health networks in order to improve patients' health. However, because of the critical nature of health-related systems, the Internet of Medical Things still faces numerous challenges, more particularly in terms of reliability, safety and security. In this paper, we present a comprehensive literature review of recent contributions focused on improving the Internet of Medical Things through the use of formal methodologies provided by the cyber-physical systems community. We describe the practical application of the democratization of medical devices for both patients and health-care providers. We also identify unexplored research directions and potential trends to solve uncharted research problems.

“…The PROTACTICAL CPS is a smart personal protective equipment that was designed to enhance firefighters' occupational health, safety, situational awareness, and comfort. It is capable of monitoring physiological and environmental parameters, locating and tracking firefighters, and detecting, in real-time, life-threating scenarios [18][19][20][21].…”

Combining different technologies is gaining significant popularity among researchers and industry for the development of indoor positioning systems (IPSs). These hybrid IPSs emerge as a robust solution for indoor localization as the drawbacks of each technology can be mitigated or even eliminated by using complementary technologies. However, fusing position estimates from different technologies is still very challenging and, therefore, a hot research topic. In this work, we pose fusing the ultrawideband (UWB) position estimates with the estimates provided by a pedestrian dead reckoning (PDR) by using a Kalman filter. To improve the IPS accuracy, a decision-making algorithm was developed that aims to assess the usability of UWB measurements based on the identification of non-line-of-sight (NLOS) conditions. Three different data fusion algorithms are tested, based on three different time-of-arrival positioning algorithms, and experimental results show a localization accuracy of below 1.5 m for a 99th percentile.

“…The perception of the current channel state can be made through a feedback closed-loop architecture or using a Link Quality Estimator (LQE) [9]. In TPC mechanisms with a closed-loop architecture, the OPTL -configured by the sensor node to transmit the data packets -is determined by the sink node.…”

In Smart Wearable Systems (SWS), the wearable devices are powered by batteries with very limited energy available. These emergent systems have strong Quality of Service (QoS) requirements, with focus on reliable communication and low power consumption. This is the scope of the Baby Night Watch, a project developed in the context of the European Texas Instruments Innovation Challenge (TIIC) 2015. This Project consists of a monitoring tool for infants, which matches different emergent research fields. SWSs require energy saving mechanism to reduce the energy wasting during wireless communications. A Transmission Power Control (TPC) mechanism that changes its characteristics according to the scenario of operation, is proposed. It uses sensors to determine the position of the infant and, based on that, predicts the current state of the channel. Other TPC algorithms are implemented and their performance are compared with our novel mechanism. The proposed TPC mechanism outperforms the existing ones in terms of the energy saving.
