ABSTRACT
The Internet of things (IoT) is a system of interrelated computing devices having unique identifiers that enable to transfer data over a network without requiring human-to-computer or human-to-human interaction. With the rapid growth in embedded wireless computing devices with high-speed Internet connectivity, body area networks comprising of interconnected several tiny-powered, wearable wireless biosensors provide an effective way of collecting vital health-related data. The emerging paradigm of the IoT in the smart healthcare system requires a specialized secure framework in order to enable real-time health monitoring, reliable diagnostics, effective treatment processes, and many other related aspects of the healthcare system. The network framework for the IoT-based healthcare system should cater to upgraded microcontroller units, IoT gateway devices, different web and wireless technologies for the IoT, variety of biosensors and data collectors, secure communication protocols, etc. These devices are continuously engaged in computation, processing, and transmission of data, which is a high-power consumption activity. On the contrary, most of these devices are battery driven, and thus, there is a strong requirement to minimize the consumption of power, thus making it an energy-efficient network. In this chapter, various 270aspects of energy consumption in the IoT framework for healthcare services are discussed.
