d) Data and data processing have been ubiquitous in businesses for decades. Companies are designing and building infrastructures to manage data, which has increased over the years. Transactional and analytical data processing are standard in most businesses.

**Massive Amounts of Data**

It’s a common theme that the Internet of Things is all about data. IoT represents a massive increase in data rates from multiple sources that need to be processed and analyzed from various Internet of Things access technologies.

In addition, various heterogeneous sensors exhibit a continuous stream of information back and forth, requiring real-time processing and intelligent data visualization with event stream processing (ESP) and IoT stream processing.

This data flow and volume shift may easily represent thousands to millions of events per second. It is the most significant kind of “big data” and will exhibit considerably more data than we have seen on the Internet of humans. Processing large amounts of data from multiple sources in real time is crucial for most IoT solutions, making reliability in distributed systems a pivotal factor to consider in the design process.

**Data Transmission**

Data transmitted between things instructs how to act and react to certain conditions and thresholds. Analysis of this data turns data streams into meaningful events, offering unique situational awareness and insight into the thing transmitting the data. This analysis allows engineers and data science specialists to track formerly immeasurable processes.

Event Stream Processing

Stream processing technology is increasingly prevalent because it provides superior solutions for many established use cases, such as data analytics, ETL, and transactional applications. It also enables novel applications, software architectures, and business opportunities. With traditional data infrastructures, data and data processing have been omnipresent in businesses for many decades.

Over the years, data collection and usage have grown consistently, and companies have designed and built infrastructures to manage that data. However, the traditional architecture that most businesses implement distinguishes two types of data processing: transactional processing and analytical processing.

Analytics and Data Handling are Changing.

– All this type of new device information enables valuable insights into what is happening on our planet, offering the ability to make accurate and quick decisions. However, analytics and data handling are challenging. Everything is now distributed to the edge, and new ways of handling data are emerging.

– To combat this, IoT uses emerging technologies such as stream data processing with in-stream analytics, predictive analytics, and machine learning techniques. In addition, IoT devices generate vast amounts of data, putting pressure on the internet infrastructure. This is where the role of cloud computing comes in useful. Cloud computing assists in storing, processing, and transferring data in the cloud instead of connected devices.

– Organizations can utilize various technologies and tools to implement event stream processing (ESP). Some popular ESP frameworks include Apache Kafka, Apache Flink, and Apache Storm. These frameworks provide the infrastructure and processing capabilities to handle high-speed data streams and perform real-time analytics. 

IoT Stream Processing: Distributed to the Edge

1: IoT represents a distributed architecture. Analytics are distributed from the IoT platform, either cloud or on-premise, to network edges, making analytics more complicated. A lot of the filtering and analysis is carried out on the gateways and the actual things themselves. These types of edge devices process sensor event data locally.

2: Some can execute immediate local responses without contacting the gateway or remote IoT platform. A device with sufficient memory and processing power can run a lightweight version of an Event Stream Processing ( ESP ) platform.

3: For example, Raspberry PI supports complex-event processing ( CEP ). Gateways ingest event streams from sensors and usually carry out more sophisticated steam processing than the actual thing. Some can send an immediate response via a control signal to actuators, causing a state change.

Technicality is only one part of the puzzle; data ownership and governance are the other. 

Time Series Data – Data in Motion

In specific IoT solutions, such as traffic light monitoring in intelligent cities, reaction time must be immediate without delay. This requires a different type of big data solution that processes data while it’s in motion. In some IoT solutions, there is too much data to store, so the analysis of data streams must be done on the fly while being transferred.

It’s not just about capturing and storing as much data as possible anymore. The essence of IoT is the ability to use the data while it is still in motion. Applying analytical models to data streams before they are forwarded enables accurate pattern and anomaly detection while they are occurring. This analysis offers immediate insight into events, enabling quicker reaction times and business decisions. 

Traditional analytical models are applied to stored data, offering analytics for historical events only. IoT requires the examination of patterns before data is stored, not after. The traditional store and process model does not have the characteristics to meet the real-time analysis of IoT data streams.

In response to new data handling requirements, new analytical architectures are emerging. The volume and handling of IoT traffic require a new type of platform known as Event Stream Processing ( ESP ) and Distributed Computing Platforms ( DCSP )

Event Stream Processing
Diagram: Event Stream Processing.

Event Stream Processing ( ESP ) 

ESP is an in-memory, real-time process technique that enables the analysis of continuously flowing events in data streams. Assessing events in motion is known as “event streams.” This reveals what is happening now and can be used with historical data to predict future events accurately. Predictive models are embedded into the data streams to predict future events.

This type of processing represents a shift in data processing. Data is no longer stored and processed; it is analyzed while still being transferred, and models are applied.

ESP & Predictive Analytics Models

ESP applies sophisticated predictive analytics models to data streams and then takes action based on those scores or business rules. It is becoming popular in IoT solutions for predictive asset maintenance and real-time fault detection.

For example, you can create models that signal a future unplanned condition. This can then be applied to ESP, quickly detecting upcoming failures and interruptions. ESP is also commonly used in network optimization of the power grid and traffic control systems.

ESP – All Data in RAM

ESP is in-memory, meaning all data is loaded into RAM. It does not use hard drives or substitutes, resulting in fast processing, enhanced scale, and analytics. In-memory can analyze terabytes of data in just a few seconds and can ingest from millions of sources in milliseconds. All the processing happens at the system’s edge before data is passed to storage.

How you define real-time depends on the context. Your time horizon will depict whether you need the full power of ESP. Events with ESP should happen close together in time and frequency. However, if your time horizon is over a relatively long period and events are not close together, your requirements might be fulfilled with Batch processing. 

**Batch vs Real-Time Processing**

With Batch processing, files are gathered over time and sent together as a batch. It is commonly used when fast response times are not critical and for non-real-time processing. Batch jobs can be stored for an extended period and then executed; for example, an end-of-day report is suited for batch processing as it does not need to be done in real-time.

They can scale, but the batch orientation limits real-time decision-making and IoT stream requirements. Real-time processing involves a continual input, process, and output of data. Data is processed in a relatively short period. When your solution requires immediate action, real-time is the one for you. Examples of batch and real-time solutions include Hadoop for batch and Apache Spark, focusing on real-time computation.

**Hadoop vs. Apache Spark** 

Hadoop is a distributed data infrastructure that distributes data collections across nodes in a cluster. It includes a storage component called Hadoop Distributed File System ( HDFS ) and a processing component called MapReduce. However, with the new requirements for IoT, MapReduce is not the answer for everything.

MapReduce is fine if your data operation requirements are static and you can wait for batch processing. But if your solution requires analytics from sensor streaming data, then you are better off using Apache Spark. Spark was created in response to MapReduce’s limitations.

Apache Spark does not have a file system and may be integrated with HDFS or a cloud-based data platform such as Amazon S3 or OpenStack Swift. It is much faster than MapReduce and operates in memory and real-time. In addition, it has machine learning libraries to gain insights from the data and identify patterns. Machine learning can be as simple as a Python event and anomaly detection script.

Back to Basics With the Internet of Things Theory

When introducing the Internet of Things theory, we need to examine use cases. We know that IoT enables everyday physical objects, such as plants, people, animals, appliances, objects, buildings, and machines, to transmit and receive data—the practical use case for IoT is bound only to the limits of our imagination.

The devices section is where we will see the most innovation and creativity. For example, there has been plenty of traction in the car industry as IoT introduces a new era of hyperconnected vehicles. Connected cars in a mesh of clouds form a swarm of intelligence.

The ability to retrieve data from other vehicles opens up new types of safety information, such as black ice and high winds detection.

A: – ) No one can doubt that the Internet has a massive impact on society. This digital universe enables all types of mediums to tap into and communicate. In one way or another, it gets woven into our lives, maybe even to the point where people decide to use the Internet as a base point in starting their businesses. More importantly, the Internet is a product made by “people.” 

B: – ) we are heading into a transformation stage that will make our current connectivity model look trivial. The Internet of Things drives a new Internet, a product made by “things,” not just people. These things or smart objects consist of billions or even trillions of non-heterogeneous devices. The ability of devices to sense, communicate, and acquire data helps build systems that manage our lives better.

C: – ) are beginning to see the introduction of IoT into what’s known as smart cities. In Boston, an iPhone app called Catchthebusapp informs application owners of public transport vehicles’ location and arrival times. GPRS trackers installed on each car inform users when they are running late.

D: – ) example proves that we are about to connect our planet, enabling a new way to interact with our world. The ability to interact, learn, and observe people and physical objects is a giant leap forward. Unfortunately, culture is one of the main factors for resistance.

 Internet of thing Theory and IoT security

Due to IoT’s immaturity, concerns about its security and privacy are raised. The Internet of Things Security Foundation started in 2015 in response to these concerns. Security is often an afterthought because there is a rush to market with these new devices.

This leaves holes and gaps for cybercriminals to exploit. It’s not just cybercriminals who can access information and data; it’s so easy to access personal information nowadays. This explains the rise in people utilizing Proxy Services to protect their identity and allow for some privacy while protecting against hackers and those wanting to obtain personal data. The IoT would benefit from this proxy service.

A recent article on the register claims that a Wi-Fi baby heart monitor may have the worst IoT security of 2016. All data between the sensor and base station is unencrypted, meaning an unauthenticated command over HTTP can compromise the system. Channels must be encrypted to overcome information and physical tampering.

Denial-of-sleep attacks

IoT also opens up a new type of DDoS attack called denial-of-sleep attacks that drain a device’s battery. Many of these devices are so simplistic in design that they don’t support sophisticated security approaches from a hardware and software perspective. Many IoT processors are not capable of supporting strong security and encryption.

IoT opens up the back door to potentially billions of unsecured devices used as a resource to amplify DDoS attacks. The Domain Name System ( DNS ) is an existing lightweight protocol that can address IoT security concerns. It can tightly couple the detection and remediation of DDoS tasks. In addition, analyzing DNS queries with machine-learning techniques predicts malicious activity.

 Internet of Things Theory: How Does it Work?

IoT is a concept, not a new technology. It connects data so applications can derive results from viewing the analytics. However, it’s a complex environment and not a journey a single company can take. Partnerships must be formed to offer a total data center-to-edge solution for a complete end-to-end solution.

Sense & Communicate

To have something participate in the Internet of Things, we must follow a few steps. At a fundamental level, we have intelligent objects that can “sense and communicate.” These objects must then be able to interact and collaborate with other things on the Internet.

These things or smart objects comprise a physical entity and a digital function. The physicals include sensory capabilities to measure temperature, vibration, and pollution data.

Sensors transmit valuable data to an Internet of Things Platform. The central IoT platform integrates data from many heterogeneous devices and shares the analytics with various applications addressing use cases that solve specific issues. The actuators perform a particular task – opening a window or a lock, changing traffic lights, etc.

Data Flow & Network Connectivity

The type of device depicts the chosen network connectivity. We have two categories: wireless and Wired. For example, a hospital would connect to the control center with a wired connection ( Ethernet or Serial ), while other low-end devices might use a Low-Power, Short-Range network.

Low-power short-range networks are helpful for intelligent homes with point-to-point, star, and mesh topologies. Devices using this type of network range between tens and hundreds of meters. They require long battery life, medium density, and low bandwidth. The device type does depict the network. If you want the battery to last ten years, you need the correct type of network for that.

Fog computing

Machine learning and IoT go hand in hand. With the sheer scale of IoT devices, there is too much data for the human mind to crunch. This results in the analysis carried out on the fly between devices or distributed between gateways at the edge. Fog computing pushes processing and computation power down to the actual device.

This is useful if there are expensive satellite links and when it is cost-effective to keep computation power at the device level instead of sending it over network links to the control center.

It’s also helpful when network communications increase the battery consumption in the sensor node. We expect to see a greater demand for fog computing systems as the IoT becomes more widely accepted and incorporated.

 6LoWPAN

Gartner released a report stating over 20 billion devices will participate in the Internet of Things by 2020. A person may have up to 5,000 devices to interact with. This type of scale would not be possible without the adoption of IPv6 and 6LoWPAN. 6LoWPAN Range stands for Low-power Wireless Personal Area Networks. It enables small, low-powered, memory-constrained devices to connect and participate in IoT.

Its base topology has several mesh-type self-healing 6LoWPAN nodes connected to the Edge router for connectivity and integration to the Internet. The edge routers act as a bridge between the RF and Ethernet networks.

Summary: Internet of Things Theory

In this digital age, the Internet of Things (IoT) has become integral to our lives. IoT has revolutionized how we interact with technology, from smart homes to connected devices. In this blog post, we explored the various aspects of the Internet of Things and its impact on our daily lives.

What is the Internet of Things?
