Question

IOT proxy operates in which layer ?

Answer 1

First, sensors usually have very limited capabilities in terms of networking connectivity. Your sensors can likely utilize Bluetooth Low Energy (BLE), just as the majority of beacons available on the market can; there is also the possibility that some of your sensors offer connectivity using the ZigBee protocol. There are also a bunch of other protocols that can be found in the Local Area Network (LAN), Home Area Network (HAN), or Personal Area Network (PAN). All of these protocols have one thing in common—they can’t directly connect to larger networks like Wide Area Network (WAN) or the Internet. You need a gateway that can provide your sensors with a single point of contact with external networks by using WiFi, GSM, or some other type of connectivity.

Answer 2

The OSI architecture consists of 7 layers and each layer is responsible for a certain functionality

The topmost layer is the application layer where the applications run.  

They are used to determine the protocols and methods that would be used by the host system.

They are also used in message exchange protocols.

The proxy data or proxy servers are stored in the application layer.

IoT stands for Internet of Things and its proxy operates in the application layer.

Hence, Application layer is the answer.
