This is the most basic and widely used IoT life cycle for IoT solutions. It consists of three layers: the perception, network, and application layers. These can be described as follows:
- The perception layer: This is the physical layer or sensing layer, which includes things or devices that have sensors to gather information about their environments. As shown in the following diagram, the perception layer of an E2E life cycle of the IoT solution in healthcare consists of patients, hospital beds, and wheelchairs that are deployed with sensors.
- The network layer: A network is responsible for connecting to other smart things, network devices, and servers. It is also responsible for transmitting and processing ...
