IoT System

An IoT system is generally classified into four main layers. The software, hardware and integrated networks of an IoT ecosystem lie within these four layers.

1. Physical Layer

This layer forms the basis of an IoT system. It is composed of several sensors, actuators and other relevant devices carefully assembled. It collects the information in the form of physical data.

2. Cloud Layer

This layer comprises computing, processing and database infrastructures. In this layer, data obtained from the physical layer is stored and processed. Predevised algorithms assess the data during this stage, and decision making is ultimately made in this layer. The Cloud layer is very effective in the clinical handling of a large volume of data, which could have potentially caused problems if managed from other resources.

3. Communication Layer

As the name suggests, this layer serves the purpose of connectivity between different layers of an IoT system. The communication layer ensures accurate data transference between different layers. Widely used communication technologies are:

Wi-Fi: Wi-Fi utilizes radio waves for establishing a network that ultimately propagates data between various computing devices. Some significant benefits of Wi-Fi are its bandwidth speed and high range of data transmission.

ZigBee: Unlike Wi-Fi, it is a personal area network. ZigBee is widely renowned in IoT based home automation. Significant gains associated with ZigBee are low power consumption, minimal expenditures, reliability and easiness.

Ethernet: It is a local area network that uses a wired system. The data transfer speed depends upon the type of wire cable being used. Ethernet is a comparatively cheap communication method, but the associated disadvantage is that it isn’t viable for more considerable distances.

4. Service Layer

This layer is the point of interaction between users and an IoT system. It allows users to visualize the refined data in the form of performance charts, spreadsheets, etc. The interface between an individual and IoT infrastructure is developed through a combination of HTML and JavaScript codes. This layer is exposed to potential cyber security threats, and hence, specific authentication protocols are deployed to account for any unwanted situation.

When it comes to your everyday home electrical appliances, IoT-based Home Automation puts the power to operate them right at your fingertips so you can save energy and money while still getting the most out of them.
