The three-layer architecture defines the main idea of the Internet of Things, but it is not sufficient for research on IoT because research often focuses on finer aspects of the Internet of Things. In a Three Layer IoT Architecture, the “Cloud” is also used to control, configure, and trigger events at the gateway, and ultimately the edge devices. Locking doors but leaving a window open isn’t enough. Security must be comprehensive or attackers simply exploit the weakest link. IoT architecture . For example, motion sensors track the motion around its coverage area; likewise, agricultural sensors have the task of checking soil, humidity or pH level. It deals with establishing the sensors and actuators in the physical or the actual environment that helps in collecting and capturing the data from the devices and the systems that are under control and observation.
