What is the role of Gateway in smart grid architecture of IoT?

Solution(By Examveda Team)

In the smart grid architecture of IoT (Internet of Things), the primary role of a gateway is to collect data from various sensors, meters, and devices deployed within the smart grid.

Gateways are responsible for acting as intermediaries between IoT devices and the central system. They receive data from distributed devices and sensors and aggregate it for transmission to the central system or Cloud. Gateways can preprocess and filter the data before forwarding it, helping to reduce network traffic and improve efficiency.

Options A (store data), B (manage data), and D (security) are also important considerations in IoT and smart grid architecture, but the primary function of a gateway, particularly in the context of smart grids, is to collect data from devices distributed throughout the grid.

Hence, the correct answer is Option C: collect data. Gateways are crucial for collecting data from IoT devices within the smart grid architecture and facilitating its transmission for further processing and analysis.
