These components are essential for the deployment of IoT-based devices:

1 i) RFID: It is a tiny chip that receives signals. It helps us to use radio waves, tags, and readers for direct automatic identification and date capture. Depending on whether power supplies are available or not, RFID tags may be passive or active.

2 ii) WSN: This is a network of autonomous sensors distributed in space. Their function is to monitor the status of RFID objects’ position, temperature, motion, etc. A sensor network’s sensing nodes transmit data to their sinks.

3 iii) Middleware: Designing of a software to hide the complexities of various technologies and make communication friendly. This architecture is termed as service-oriented architecture.

4 iv) Cloud & Fog Computing: It is a computing model for accessing the on-demand pool of computers, networks, servers, storage, databases, utilities, software, etc. There are several problems with IoT cloud computing, including synchronization, standardization, balancing, reliability, and management. The extension of cloud computing services to the vicinity of users has improved efficacy with the assistance of fog computation. Fog computation includes characteristics such as location, distribution, scalability, support for mobility, interactive real-time services, and fly analysis [6].

5 v) IoT Application Software: Piece of code for the development of various industry-oriented applications. All services are provided for the same reason.
