Communication Protocols in IoT: Connecting the Digital Dots
START
The Internet of Things (IoT) has revolutionized the way we interact with everyday objects. From smart homes to industrial automation, IoT devices rely on robust communication protocols to exchange data seamlessly. In this article, we’ll explore the key communication protocols that power the IoT ecosystem.
Payment Processing
Action: The invoice is verified against the purchase order and delivery documentation, and payment is processed.
Document: Payment receipts or remittance advices are issued once payment is completed.
Link Layer Protocols
Network Layer Protocols
Transport Layer Protocols
Application Layer Protocol
Payment Processing
Action: The invoice is verified against the purchase order and delivery documentation, and payment is processed.
Document: Payment receipts or remittance advices are issued once payment is completed.
Link Layer Protocols
At the foundation of IoT communication lies the Link Layer. Here are the top five protocols in this layer:
- Ethernet: A tried-and-true protocol used for wired connections. Ethernet ensures reliable data transfer over local networks.
- Wi-Fi: Ubiquitous and versatile, Wi-Fi enables wireless communication between devices within a certain range. It’s commonly found in smart homes and offices.
- WiMAX: Although less common, WiMAX provides high-speed wireless connectivity over longer distances.
- Low-Rate WPAN (Wireless Personal Area Network): Ideal for low-power devices, WPAN includes protocols like Zigbee and Bluetooth.
- Mobile Communication (5G, 4G, 3G): Cellular networks play a crucial role in IoT, especially for remote and mobile applications.
Payment Processing
Action: The invoice is verified against the purchase order and delivery documentation, and payment is processed.
Document: Payment receipts or remittance advices are issued once payment is completed.
Network Layer Protocols
The Network Layer handles routing and addressing. Key protocols include:
- IPv4: The older version of the Internet Protocol, still in use but gradually transitioning to IPv6.
- IPv6: With its 128-bit addresses, IPv6 accommodates the growing number of IoT devices. It’s the future of IP addressing.
- 6LoWPAN: An adaptation layer that allows low-power devices to communicate using IPv6.
Payment Processing
Action: The invoice is verified against the purchase order and delivery documentation, and payment is processed.
Document: Payment receipts or remittance advices are issued once payment is completed.
Transport Layer Protocols
The Transport Layer ensures reliable data transfer. Two main protocols dominate here:
1. TCP (Transmission Control Protocol):
- Highly reliable with error control, flow control, and congestion control.
- No packet loss—each sent packet expects an acknowledgment.
- Ideal for critical data.
2. UDP (User Datagram Protocol):
- Lightweight and simple.
- Commonly used for audio and video streaming.
- No acknowledgment needed—suitable for non-critical data
Payment Processing
Action: The invoice is verified against the purchase order and delivery documentation, and payment is processed.
Document: Payment receipts or remittance advices are issued once payment is completed.
Application Layer Protocol
The Application Layer serves end-users and applications. Notable protocols include:
1. MQTT (Message Queuing Telemetry Transport):
- Widely used for IoT communication.
- Publish-subscribe model.
- Lightweight and efficient.
- Perfect for vehicle-to-vehicle communication.
2. SMQTT (Secure Message Queue Telemetry Transport):
- An extended version of MQTT.
- Focuses on lightweight attribute encryption.
- Enhances security for sensitive data.
