Need for Gateway In WSN | Gateway Concepts In WSN | Wireless Sensor Networks

A Gateway is an essential component in a Wireless Sensor Network (WSN) as it acts as an intermediary between the sensor nodes and the outside world. The main reason for having a Gateway in WSN is to provide an interface for the transfer of data from the sensors to the central processing unit or to the cloud for further analysis. The Gateway is responsible for collecting data from the sensor nodes, aggregating it, and forwarding it to the target destination. It also provides the necessary security measures for the network and helps in addressing the scalability and reliability issues. The Gateway also helps in reducing the communication overhead by reducing the number of data transmissions between the sensor nodes and the target destination. The need for a Gateway in WSN arises due to the limited resources and energy of the sensor nodes and the requirement of a reliable and secure communication channel.
