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.
