What is IoT protocol stack?

Abstract. The IoT protocol stack can be visualized as an extension of the TCP/IP layered protocol model and is comprised of the following layers: physical layer, link layer, network layer, transport layer, application protocol layer, and application services layer.

What are the different IoT protocols explain?

Among many others, there are protocols used in connectivity infrastructure (e.g. 6LowPAN), communications (Wi-Fi, Bluetooth), data transmission (MQTT, CoAP, XMPP), security (DTLS), and device management as well as telemetry (LwM2M).

What is a protocol stack briefly describe with an example?

A protocol stack is a group of protocols that all work together to allow software or hardware to perform a function. The TCP/IP protocol stack is a good example. Protocols for specific functions such as e-mail (Simple Mail Transfer Protocol, SMTP) and file transfer (File Transfer Protocol, FTP) reside at this level.

What is protocol stack in LTE?

The protocol stack functions consist of the Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC). LTE is the latest generation of the 3GPP standards. The LTE standard specifies an IP-only network supporting data rates up to 150 Mbps.

What are the seven layers of OSI model?

OSI Model Explained: The OSI 7 Layers

1. Physical Layer.
2. Data Link Layer.
3. Network Layer.
4. Transport Layer.
5. Session Layer.
6. Presentation Layer. The presentation layer prepares data for the application layer.
7. Application Layer. The application layer is used by end-user software such as web browsers and email clients.

What is protocol protocol stack?

The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family. Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.

Why is it called a protocol stack?

The Data Link layer has other protocols associated with its data type and is responsible for the addressing of data from the other layers. When protocols are able to interact in such a way so in a combined activity, such as in TCP/IP and the OSI model, they are called a protocol stack.
