TopIntroduction
IoT applications appear to benefit human beings in many commonplace fields (Bainbridge & Steinberg, 2010; Celdrán, Clemente, Pérez, & Pérez, 2016; Gubbi, Buyya, Marusic, & Palaniswami, 2013; Murty et al., 2008). One of its advantages is that it can enrich people’s environments in a much intuitive status. Health care, critical monitoring, and controlling are significant factors in people's lives, and can greatly benefit from the development of IoT technologies. In health, IoT technologies such as RFID, WSN, and smartphones offer complete cooperative biomedical services in hospitals and homes to monitor and track patients’ activity. Amendola et al. (Amendola, Lodato, Manzari, Occhiuzzi, & Marrocco, 2014) studied IoT applications for people's health and wellness. For example, RFID tags used to sense volatile compound materials are positioned in walls, food and drug locations, fire detection devices, and high heat indoor appliances. Similarly, an RFID labeling chip implanted in a human body can provide real-time or on-demand patient’s status. Rohokale et al. (Rohokale, Prasad, & Prasad, 2011) proposed a cooperative IoT approach to monitor and control health in rural locations. Their model can monitor heartbeats, as well as blood pressure and blood sugar levels, which can be used for energy efficient motherhood health-care programs. In critical or emergency cases, such as heart attacks, installed IoT nodes with ECG and gyroscope sensors can monitor irregular heartbeats or sense if a patient has fallen in their indoor environment, and subsequently send a real-time notification to the person in charge, such as a family physician or a relative. This notification is based on a cooperation threshold between all sensors for specific monitoring and tracking requirements.
Fuzzy computing has been adopted in the literature to overcome uncertainty or vagueness in diverse people’s commonplace applications. Fuzzy inference systems are leveraged in many applications and usages (Elizabeth J. Chang, Omar K. Hussain, 2013), one of which is to enrich the revolution of smart environments that are a part of IoT applications to provide awareness about the quality of location. People often tend to reside and have their well-beings in locations where nowadays pollution sources are declined to the minimum exposure (European Environment Agency, 2016; Stansfeld, 2015). IoT is capable to enrich people’s understanding of their environments in a way that can provide awareness in their places of interest, so they can be alerted of events that have health impact or lack of quietness vulnerability (Perera, Zaslavsky, & Christen, 2014). Measuring people’s environment whether indoor or outdoor is normally done through using a measurement unit per sensory data value. For example, inferring a quality of indoor location may involve air quality, noise, temperature and/or motion to measure pollution level, sound intensity, room temperature in C or F, and/or human movement. This method only gives a one-dimensional aspect of sensory feedback. The complexity of understanding people’s surroundings requires a system that captures people’s preferences of locations like crowdedness level, reading-suitability, atmosphere quality, etc. and reacts according to their desires. The Quality of location plays an important role in people’s daily lives and ubiquitous environments (Andersen et al., 2011; Cai et al., 2017).
