The efficiently designed e-healthcare system focuses on monitoring the patients remotely, analysing their health conditions, to avoid critical health conditions and to give them better life with the help of IoT (devices) An environment surrounded with connected devices, people, time, places and network is needed. IoT has become an essential part of e-healthcare system. But as the IoT is exaggerating, few challenges regarded security and privacy issues of person’s medical data are also raised gradually. Moreover this, WBAN (Wireless Body Area Network) is the part of internet of things, which are enabled with patient’s body. Communications among respective sensors are made and information is passed to other sensors implanted in healthcare systems [14]. According to received data/ information, doctor takes a decision and provides treatment to patient accordingly (remotely). Sometimes when a patient is in a crucial/ critical condition, he/ she is unable to move, in such case, these smart devices plays an essential to take care or personal care of patients. Hence, this section discusses importance of IoT based e-healthcare in current era. Now, next section will discuss about several attacks or vulnerabilities or threats on e-healthcare systems.

Whereas all wireless networks use a fixed frequency spectrum to exchange data, cognitive networks search for a spectrum hole and use that white space for wireless transmission (and reception). Users of CRNs are referred to as secondary users, in that they do not own the spectra that they use. The authors argue that CRNs can be employed in body area networks (BANs). A BAN is the wireless interconnection of a number of medical devices that monitor the state of a patient often in a critical condition [23]. The current state of BANs uses unlicensed technologies, for example Wi-Fi and Bluetooth, which are prone to interference from other users. The authors of Chapter 9 propose that short-range communication between medical devices can be managed using a CRN. The idea is that the devices would determine the best possible spectral space and transmit data over that space.

From the subset of surface sampling studies that attempted to evaluate SARS-CoV-2 infectivity, only two peer-reviewed studies have isolated viable virus from a surface sample. SARS-CoV-2 was successfully cultured from multiple surface samples (n = 6) collected from an ICU room where a patient was receiving high flow oxygen therapy via nasal cannula (Ahn et al. 2020). Viable virus was only isolated from surface samples collected in close proximity to the patient (<6 ft)(Ahn et al. 2020). Another study was able to culture virus from a surgical mask that was worn by a COVID-19 patient in critical condition (Hu et al. 2020). Virus could only be cultured from one of the nine masks that were positive for SARS-CoV-2 RNA collected from COVID-19 patients who had a range of health conditions, from critically to severely to mildly ill (Hu et al. 2020).

The use of technology in the health sector has increased over the years, with the aim of providing efficient and quality services in order to save lives. Telemedicine is a beneficial use of technology in the health sector since it provides virtual treatment and service for patients by physicians. The physician can either be in a remote place while the patient is at a healthcare facility, or the patient can be in a remote place while the physician is at the facility. The distance between the patient and the physician is a major motivation for employing telemedicine operations. It helps to bring needed physician attention to patients that are far away, especially if the patient is in critical condition (Rajan et al., 2019). Time management is also a major motivation due to the fact that virtual visits are more convenient and take less time. The average in-office visit takes 121 min, including 101 min of commute and waiting room time, only 20 min with the doctor,” compared to an average wait time of five minutes for virtual visits (Care-innovation, 2019). In the cases of communicable infectious diseases, like COVID-19, telemedicine helps to reduce the risk of exposure to both the physician and the patient. Telemedicine is also effective for cost management, which results in lower rates compared to in-person visits. It also generates savings by avoiding the use of emergency wards, which by far the most expensive of the alternate care options provided (Cheney, 2019). The use of remote services in healthcare industry plays a significant role in the provision of services in underserved areas such as cardiology, pediatrics, psychiatry, and neurology by providing accessibility to the relevant expert physicians.

The last revolutionary advances in micro-electronics and wireless communication technologies allowed the development of new and cheap sensor nodes. These devices are able to communicate data through a wireless medium without human intervention, which form wireless sensor networks (WSNs) [1]. Their flexibility, simplicity and low cost node make them a good solution to be deployed in different areas. WSN can be used in unreachable places where human intervention is very risky and sometimes impossible, such as an earthquake, the flood hit area [2] contaminated regions [3]. Also, this kind of networks can be used for different application, military [4], and security related areas, environmental [5], home automation [6], smart place, medical monitoring [7]. The application in medical is called wireless body area network (WBAN). The WBAN is a subfield of the WSN, continuously observing the health status of a patient is the main intention of WBAN in order to generate an alarm when the critical condition is found. These networks are composed of tiny biomedical nodes, dedicated to ensuring a continuous monitoring of physical or vital information of patients; it has become one of the enabling technologies that provide many successful applications in medical and nonmedical field. WBAN is able to communicate sense and process the physiological data by placing intelligent biosensors inside or outside the human body that accumulate the physical information and transmit to the base station for further processing. These biosensor nodes are simple, heterogeneous, cost effective, placed on different parts of the human body and can capture many data as blood sugar, EMG, ECG, EEG and temperature. Some biosensors and their functions are shown in Table 1. These data are routed to the server for further analysis [8].
