1.1 Introduction
The modern era is defined for its automation and industrialisation, with rapid exchange of human labour for its automation counterpart. This automation is driven by the presence of innumerable sensors and transducers across all walks of life. All these sensors generate electrical signals based on certain environmental conditions. For each condition, defined by parameters such as temperature or humidity, an electrical response is noted, giving rise to multiple datasets. According to the US National Science Foundation, approximately 20 billion sensors are going to be connected to the global network by 2020, which is an exponential growth to say the least [1ā3].
Most companies now have a digital footprint, and as a consequence, huge numbers of objects, connected to various types of networks, will need efficient and precise data flow. Otherwise, the entire economy can be hampered due to a sudden glitch, since more and more businesses are dependent on information coming from continuous monitoring of these connected objects. The basic concept is that humans are in touch with the world through connected objects distributed over a network. In other words, humans and their surroundings are connected through distributed sensors over a network of networks, the internet [4]. This concept of all-pervading connectivity was first proposed by British innovator Kevin Ashton in 1999. He coined the phrase āInternet of Thingsā, or IoT, as it is often referred [5]. Though it was futuristic at that time, within 20 years IoT was standardised as a protocol in many applications [6ā10].
After its inception and initial hiccups, IoT has slowly become a buzzword. The term now effectively amalgamates data acquisition, data storage and data analysis. Every day new applications are being designed and implemented since IoT has cut down the time to market for a product due to familiarity and format. Typical applications of IoT include the following, and this is in no way an exhaustive list:
- Telecom [11ā13]
- ERP [14,15]
- E-governance and law enforcement [16,17]
- Smart home and smart city [18ā20]
- Renewable energy [21,22]
- Healthcare and medical technologies [23ā25]
This book chapter concentrates on the final one, covering the health sector. This sector more than any other domain has a telling effect on human lives, and it does so instantaneously. The domain is termed MIoT, or IoT applied in the field of medical technologies and healthcare, and many of the advanced countries are investing heavily to harness its benefits. A few of the plans are mentioned below:
- Chinaās National IoT Plan by the Ministry of Industry and IT
- European Research Cluster on IoT (IERC)
- Japanās u-Strategy
- UKās Future Internet Initiatives
- Italian National Project of Netergit
- NIST report for cyber-physical systems and IoT in the United States [23,26ā29]
The Indian governmentās (GoI) Digital India Mission includes a health portal and central storage of health-related medical data as well as image storage [30,31].
The predominant reason for this huge investment, particularly in the case of India, is the scarcity of suitable medical care and treatment for ordinary people, which will be discussed in Chapter 2 [32]. In recent times, private medicare has compounded the cost with an increase in insurance premiums.
This situation clearly points to the need for a drastic reduction in the number of patients who need to be seen in hospitals or clinics versus those who can use continuous health monitoring. In addition, it points to the importance of preventive medicine [33]. It calls for an emergency technology intervention, or ādisruptive technologyā, and we believe MIoT is going to occupy that place. Previously, similar needs were catered to by using an ensemble of technologies that were referred to as ābiotelemetryā, or biomedical telemetry [34,35]. Now, with the help of cloud computing, IoT has enabled the basic information to be uploaded on a platform that is interoperable and immediately accessible [32,36ā39]. Apart from the reduction of patients who need to be in hospitals, other pertinent needs can be smoothly managed using this technology. In the following section, we discuss this technology in detail as well as a few future and special needs. This goes to show that in the presence of a simple, stable and predictable platform, many innovations can take place, driving the economy.
1.2 Need Analysis and Beneficiaries
In this section, we illustrate a need analysis with a few specific cases. Many sections of society are influenced by MIoT, and we should be prepared for a behavioural shift in medical management if this technology is introduced internationally [40ā42].
Consider the relationship between patients and doctors. Globally, there is a lack of affordable healthcare for moderate income groups and the poor. Already, there is a huge emphasis on preventive medicine, which aims to monitor health or promote regular health check-ups. According to the Indian National Health Profile, a wing of Ministry of Health, GoI, only around 1 allopathic doctor per 11,000 patients is available. (This information was obtained from 2018 data.) This is far below the World Health Organizationās global standard doctor and patient ratio of 1:1,000 [30,32]. There are many ...
