Question: Which Protocol Is Lightweight HTTP MQTT CoAP SPI?

Which of the following is more lightweight protocol among listed below?

Which of the following is more light weight protocol among listed below.

Explanation: MGCP stands for Media Gateway Control Protocol.


What is BLE protocol?

Bluetooth Low Energy (BLE) is a low power wireless communication technology that can be used over a short distance to enable smart devices to communicate. … BLE is a relatively new Bluetooth standard defined by the Bluetooth Special Interest Group (SIG) with a focus on low energy.

Is CoAP secure protocol?

CoAP uses DTLS as a secure protocol and UDP as a transfer protocol. Therefore, the attacks on UDP or DTLS could be assigned as a CoAP attack. An attack on DTLS could possibly be launched in a single session and a strong authentication mechanism is needed.


The Constrained Application Protocol (CoAP), although inspired by HTTP, was designed to use UDP instead of TCP. The message layer of the CoAP over UDP protocol includes support for reliable delivery, simple congestion control, and flow control.

What is IoT with diagram?

The Internet of Things (IoT) is about interconnecting embedded systems, bringing together two evolving technologies: wireless connectivity and sensors. These connected embedded systems are independent microcontroller-based computers that use sensors to collect data.

What is the equation of IoT?

The success equation: IoT = OT + IT “IoT” is well named because it represents the merger of “IT” or Information Technology and “OT” or Operational Technology. While these technology spaces usually exist on different sides of a company, IoT solutions must combine them if they’re to work successfully.

What does MQTT stand for?

MQ Telemetry TransportWhat does MQTT stand for? It stands for MQ Telemetry Transport. It is an extremely simple and lightweight messaging protocol (subscribe and publish) designed for limited devices and networks with high latency, low bandwidth or unreliable networks.

Where is CoAP used?

CoAP is designed to enable simple, constrained devices to join the IoT even through constrained networks with low bandwidth and low availability. It is generally used for machine-to-machine (M2M) applications such as smart energy and building automation.

Which IoT protocol is lightweight?

Data Protocols. “The MQTT protocol enables a publish/subscribe messaging model in an extremely lightweight way. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.”

Which layer protocol is CoAP?

application layer protocolCoAP is one of the latest application layer protocol developed by IETF for smart devices to connect to Internet.

Which protocol is used in IoT?

HyperText Transfer Protocol is the best example of IoT network protocol. This protocol has formed the foundation of data communication over the web. It is the most common protocol that is used for IoT devices when there is a lot of data to be published.

Is ble in IoT protocol?

The new Bluetooth Low-Energy (BLE) – or Bluetooth Smart, as it is now branded – is a significant protocol for IoT applications. Importantly, while it offers similar range to Bluetooth it has been designed to offer significantly reduced power consumption.

Does CoAP can be applied for high end networks?

5.4. CoAP, Constrained Application Protocol, is a RESTful application protocol running over UDP that is used for resource-constrained, low-power devices in lossy networks, especially optimized for deployments with a high number of end devices within the network.

Is XMPP open standard?

Unlike most instant messaging protocols, XMPP is defined in an open standard and uses an open systems approach of development and application, by which anyone may implement an XMPP service and interoperate with other organizations’ implementations.

Which is an open standard HTTP MQTT Xmpp CoAP?

Explanation: MQTT is a public messaging protocol designed for lightweight M2M communication. It was originally developed by IBM and is now an open standard. … Two of the most promising for small devices are MQTT and CoAP. Both ate standard protocols.

What is ble in IoT?

Bluetooth Low-Energy (BLE), which launched in 2009, set the stage for future applications in IoT as the field was taking off. BLE is a specification targeting primarily small-scale IoT applications like wearables and broadcasting beacons that require devices to send small amounts of data using minimal power.

What is Bluetooth low energy protocol for IoT?

Bluetooth Low Energy is a great protocol for IoT devices that rely on limited power supplies. … BLE sensors can measure any parameters from any person, showing the data directly on a mobile device, which also analyzes the data and suggests the different actions that need to be taken based on said data.

Is Bluetooth an IoT?

Recent developments in Bluetooth are set to position the technology as ‘the communication protocol of choice’ for IoT. … In fact, Bluetooth with its ability to connect disparate devices and industries through short-range technology can transform the way devices interact with each other.
