Abstract: Recent technological advancements in wireless low power/low range communication systems, MicroElectroMechanical Systems (MEMS) technology and integrated circuits have enabled low-power, intelligent, miniaturised, nano-technology sensor nodes strategically placed around the human body to be used in various applications, such as wearable wireless healthcare monitoring systems. This exciting new area of research is called Wireless Body Area Networks (WBANs) and leverages the emerging IEEE 802.15.6 and IEEE 802.15.4j standards, specifically standardised for Internet of Medical Things (IoMTs). This tutorial provides a survey on the current state-of-art of WBANs based on the latest standards which enable IoMTs with a range of representative applications. From these applications, we will abstract out the major challenges to realising the wearable wireless sensors systems for healthcare monitoring applications. Part I of the tutorial will start with an overview of WBANs, with a focus on the fundamental concepts of healthcare sensor hardware and measurement circuits. Furthermore related low power /low range wireless communication technologies and standards used for WBANs, the challenges and impairments of wireless media for IoMTs will be addressed. Introduction session will conclude by addressing the data acquisition and validation techniques for processing the healthcare data collected from the wearable wireless sensor networks. In Part II of the tutorial, the key design issues for wearable Activity Recognition systems, as an example of healthcare applications, will be presented. Design issues with respect to type/number/location of sensors according to the purpose of the application will be discussed. Emerging IoMTs research opportunities and challenges will be discussed in Part III of the tutorial. Topics in this section cover both theoretical and practical aspects, including the wearable system limitations, selection of attributes and sensors, obtrusiveness, data collection protocols, recognition performance criteria, energy consumption, processing and user flexibility. Open issues and challenges within each area are also explored as a source of inspiration towards future developments in WBANs. An activity recognition prototype demonstration will conclude the tutorial to provide the practical aspects and challenges for a wearable wireless sensor network solution.
