Request Response Communication Model in IoT

Publish Subscribe Communication Model in IoT

Push Pull Communication Model in IoT

Exclusive Pair Communication Model in IoT

What is it?: This model operates under a classic client-server paradigm where a client sends a request and awaits a response from the server

Request Response Communication Model in IoT

Characteristics: Known for its simplicity and reliability, it ensures that each request is matched with a response, making error handling straightforward

Recommended Use: This model is particularly useful in environments where confirmation of data receipt is required, such as in transactional systems where each action must be validated.

Elements: Includes clients that initiate requests, servers that respond, and the communication protocols that facilitate these interactions.

Request Response Communication Model in IoT

What is it?: In this model, publishers send messages to a message broker that distributes these messages to subscribers based on pre-defined topics.

Publish Subscribe Communication Model in IoT

Characteristics: It reduces the coupling between data producers and consumers, supports one-to-many communication efficiently, and facilitates dynamic subscriber management.

Recommended Use: It excels in applications that require high scalability and where publishers and subscribers dynamically change, such as in large-scale sensor networks or multimedia content distribution.

Elements: Consists of a message broker, topics under which messages are published, publishers that send messages, and subscribers that receive them.

Publish Subscribe Communication Model in IoT

What is it?: This dual-method model involves pushing data to a storage or processing node and pulling it by consumers as needed.

Push Pull Communication Model in IoT

Characteristics: By combining proactive push and reactive pull methods, it manages data flow efficiently, allowing for better control over when and how data is accessed.

Recommended Use: This model is ideal for applications with asynchronous data generation and consumption patterns, such as in streaming data applications or batch processing systems.

Elements: Features data producers who push data, data storage or aggregation points, and consumers who pull data on demand.

Push Pull Communication Model in IoT

What is it?: Forms a dedicated communication link between exactly two devices, ensuring a private and controlled data exchange.

Exclusive Pair Communication Model in IoT

Characteristics: Provides a high level of security and reduces the likelihood of data interception, as the communication channel is not shared with other devices.

Recommended Use: Best suited for scenarios requiring stringent data security measures, such as in military communications, medical device interactions, or other sensitive applications.

Elements: Comprises two paired IoT devices that communicate directly, exclusive communication channels, and typically robust encryption protocols to safeguard data transfer
