2.1. Health
The integration of health care with IoT (Bansal et al., 2018) helps the patients to get medical care quickly and easily. IoT exhaust a new lifeline in the healthcare sector by enhancing the sensor-enabled device techniques and by compounding the other techniques such as RFID (Jia et al., 2012) (radio frequency identification system), Bluetooth, Wi-Fi (Saraswathi et al., 2016). In case of an emergency with the help of IoT, doctors can monitor patient’s health from a remote location (Ani et al., 2017) and provide the related treatment. In the diagnosis of many chronic diseases (Raji et al., 2016) such as asthma, heart attack, kidney, cancer, diabetes (Chui et al., 2017; Islam et al., 2015) IoT plays a significant role. IoT is a boon for old age people, it helps in their activity and movement recognition of elderly people (Bisio et al., 2017), helps in the Alzheimer etc. IoT based e-healthcare system (Farahani et al., 2018) is a patient-based healthcare system in which doctor, hospitals, patients are connected to each other by using IoT, cloud computing, and fog computing. This e-health service of IoT plays an important role in providing better healthcare services such as mobile healthcare, assisted living, e-medicine care, early warning systemsdda to the patients. IoT plays an important role in bioinformatics-based healthcare (Chang, 2018) for the analysis and visualization of tumors and genes (Chang, 2018) that contributes to the development of cancer.
