Bluetooth is a wireless technology that allows devices to communicate over short distances. It is commonly used in IoT devices for connecting to sensors, actuators, and other nearby devices.

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for IoT devices. It is optimized for low-bandwidth and high-latency networks, making it suitable for IoT applications.

Cellular networks are widely used for long-range communication in IoT devices. They provide reliable and secure connectivity over large distances, making them suitable for applications such as remote monitoring and control.

HTTP (Hypertext Transfer Protocol) is a widely used protocol for transferring data between IoT devices and cloud platforms. It is a versatile protocol that supports various data formats and can be easily integrated with existing web applications.

TLS (Transport Layer Security) is a widely used security protocol for protecting data transmitted over the internet. It provides encryption and authentication, ensuring the confidentiality and integrity of data.

Wi-Fi (Wireless Fidelity) is a wireless technology that allows devices to connect to a local area network (LAN). It is commonly used for connecting IoT devices to a home or office network.

UDP (User Datagram Protocol) is a communication protocol that is commonly used for real-time data streaming in IoT applications. It provides low-latency and high-throughput data transfer, making it suitable for applications such as video streaming and sensor data collection.

Cellular networks are commonly used for connecting IoT devices to a wide area network (WAN). They provide reliable and secure connectivity over large distances, making them suitable for applications such as remote monitoring and control.

DNS-SD (Domain Name System Service Discovery) is a communication protocol that is commonly used for device discovery and configuration in IoT networks. It allows devices to automatically discover each other and exchange information such as IP addresses and services.

IPsec (Internet Protocol Security) is a security protocol that is commonly used to protect data transmitted between IoT devices and a gateway. It provides encryption and authentication, ensuring the confidentiality and integrity of data.

Bluetooth is a wireless technology that allows devices to communicate over short distances. It is commonly used for connecting IoT devices to a personal area network (PAN), such as a smartphone or tablet.

TCP/IP (Transmission Control Protocol/Internet Protocol) is a communication protocol that is commonly used for transferring data between IoT devices and a local server. It provides reliable and secure data transfer, making it suitable for applications such as data collection and control.

TLS (Transport Layer Security) is a security protocol that is commonly used to protect data transmitted between IoT devices and a cloud platform. It provides encryption and authentication, ensuring the confidentiality and integrity of data.

Zigbee is a wireless technology that is commonly used for connecting IoT devices to a mesh network. It is a low-power, low-data-rate technology that is suitable for applications such as home automation and industrial control.

MQTT (Message Queuing Telemetry Transport) is a communication protocol that is commonly used for transferring data between IoT devices and a fog node. It is a lightweight protocol that is optimized for low-bandwidth and high-latency networks, making it suitable for IoT applications.
