Architecture of IoT Analytics Systems

There are 4 layers in IoT architecture are highlighted below: 

1. Hardware/Sensing Layer 

This layer serves as the foundational level of the IoT architecture, comprising hardware devices connected to the network layer. Wireless Sensor Networks (WSN) and radiofrequency identification (RFID) serve as the two primary building blocks of IoT. Arduino Microcontrollers are directly linked with the sensors, and they are further connected to the Raspberry Pi. The Raspberry Pi, in turn, connects to the Internet via Ethernet or WiFi. It facilitates the real-time transmission of data collected from sensors to the server. 

2. Network/Gateway Layer 

This layer serves as the bridge between the Hardware/Sensing Layer and the Management Layer. Here, digitized data is received and routed over wired LANs, WiFi, or the Internet for further processing. Various protocols can be employed for communication between IoT gateways and servers, including MQTT, AMQP, COAP, and HTTP. We will discuss different protocols in the following section. 

3. Management Layer 

This layer is responsible for data modeling and security control. It serves as the hub for all data handling and processing operations. Here, the necessary data is extracted from the information transferred by the sensors. 

4. Application Layer 

This layer represents the final stage of the IoT analytics architecture, utilizing the data processed by the management layer

Real-Time Stream Processing in IoT Environments

Real-time stream processing involves the immediate processing of data streams collected from IoT devices in real-time. Discover more about open-source tools for real-time analytics platforms, which facilitate this processing. The tasks that can be included in this processing are: 

1. Transformation - It includes the conversion of the data which is collected from the IoT device. After this conversion, the resulting data is transferred for further analytics. 

2. Data Enrichment - The data enrichment process is the operation in which the sensor-collected raw data is combined with the other dataset to get the results. 

3. Storing Data - This task includes storing the data at the required storage location.

Most Common Protocols Used in IoT Analytics

The below mentioned protocol are most widely used: 

1. MQTT 

• MQTT is an efficient publish/subscribe protocol ideal for low bandwidth or unreliable network conditions, frequently utilized for remote sensor data collection. 

• The MQTT broker serves as a centralized communication point where clients publish and subscribe to topics to exchange messages. 

2. CoAP 

• The Constrained Application Protocol (CoAP) is designed for simple, constrained devices and facilitates web based, RESTful interactions using familiar methods like GET, PUT, POST, and DELETE. 

• It is particularly well suited for constrained networks and power limited IoT devices. 

3. AMQP 

• AMQP (Advanced Messaging Queuing Protocol) is an open standard for passing messages in between applications and organizations. It connects system, provides business processes with the information they need. 

4. HTTP 

• This is the standard protocol for web services and still is used in its solutions. The most popular architectural style, called RESTful, is widely used on mobile and web applications and must be considered in IoT Solutions.

5. DDS 

• DDS stands for Data Distribution Service, which is a standard for real time IoT analytics and scalable and high-performance machine-to-machine communication. DDS can be deployed in both low-footprint devices and on the cloud as well.

Comparative Overview of IoT Architecture Across Platforms

1. Xenonify IoT Architecture

• Data Collection and Ingestion - This will be the first step in data handling from the IoT device. We have different options to collect data from the sensors. In the upcoming paragraph, we are going to discuss data ingestion using a different platform. 

• Using Apache NiFi - Apache MiNiFi, a subproject of Apache NiFi, can be deployed on the Raspberry Pi for lightweight and resource-efficient data collection. With MiNiFi, data from sensors can be collected and routed to Apache NiFi. From there, the data can be further routed to multiple desired destinations. The second method involves directly ingesting data from the MQTT broker and routing it to multiple destinations as needed. To accomplish this, we must design a data flow pipeline using various Apache NiFi processors. 

• Using Stream Sets - By Using StreamSets Data Collector Edge StreamSets data collector Edge is an ultralight agent for the IoT, which collects the data and sends it to the stream sets. The second method involves direct ingestion of data from the MQTT broker and routing it to multiple destinations as needed. To achieve this, we need to design a data flow pipeline using various StreamSets processors. 

• Data Processing - Xenonify provides you with a platform that you can use to build your own IoT analytics platform for the data collected from the sensor. Apache Spark is being used by Xenonify at the data processing stage. The speed of the data stream can also vary according to the time. So, Our Data Pipeline should be able to handle data of any size and at any velocity.
