Trust-Based Communication Systems for Internet of Things Applications

Keywords: IoT, mobile computing, smart home, wearable, etc.

The IoT is an integrated system that looks at material with different levels of processing, hearing, and performance sharing that communicates as their integrated Internet platform as shown in Figure 1.1. The main purpose of the IoT, therefore, is to make things connected to other things and people, using any network, route, or service, anytime, anywhere.

Figure 1.1 IoT.

The IoT is increasingly being considered the next step in the evolution of the Internet. Devices such as Smartphones, cars, industrial systems, cameras, toys, buildings, household items, industrial systems, and countless others can exchange information via the Internet these days. These devices can perform fine-tuning, tracking, setting, control, real-time monitoring, and process control regardless of their size and functions [1]. The widespread proliferation of Internet-enabled devices has taken place in recent years.

The Internet certainly become a part of the life of a social animal. It is a big room for people and knowledge. The Internet first emerged as the “Computer Internet.” It is a digital network where it is possible to incorporate several services on top of it, such as the World Wide Web. It was an age of information sharing. There were several social websites that kept individuals linked all the time. This has led to the Internet being loaded with individuals rather than data. Technology, on the other hand, has been progressing day by day. A period of “MobiComp” (mobile computing) has also begun [2–4].

Mobile internet services for 3G and 4G have now resulted in quicker internet connectivity and increased video call quality. Mobile computing and wireless technology have become inexpensive and have gained more popularity. Therefore, there was a new computer-Ubiquitous computing.

Figure 1.2 Growth of Internet of Things.

Intelligent space and minimal user participation are the subjects of this computing. Advances in technology have contributed to a reduction in size for smartphones and other portable devices. Ordinary mobiles and PCs have been replaced by smart phones, i-pads, laptops, and notebooks. There was also a shift in the device through which individuals access the internet. This, in turn, resulted in the configuration of sophisticated functions.

Devices were not only connected to the internet in such a situation, but also sensed, computed, and performed intelligent tasks. Later, physical items were programmed with identification tags such as bar code and RFID so that devices such as smart phones could scan them and upload their information to the internet. With the aid of a smart computer, this way of linking the real world with cyberspace contributed to the internet being called the “Internet of Things”. Figure 1.2shows that it has its origins in mobile computing, ubiquitous computing, and IT [5]. Therefore, from the above, IoT transforms the view of connectivity from “any-time, anywhere” for “anyone” to “any-time,” any-place” for “any-thing”.

These components are essential for the deployment of IoT-based devices:

1 i) RFID: It is a tiny chip that receives signals. It helps us to use radio waves, tags, and readers for direct automatic identification and date capture. Depending on whether power supplies are available or not, RFID tags may be passive or active.

2 ii) WSN: This is a network of autonomous sensors distributed in space. Their function is to monitor the status of RFID objects’ position, temperature, motion, etc. A sensor network’s sensing nodes transmit data to their sinks.

3 iii) Middleware: Designing of a software to hide the complexities of various technologies and make communication friendly. This architecture is termed as service-oriented architecture.

4 iv) Cloud & Fog Computing: It is a computing model for accessing the on-demand pool of computers, networks, servers, storage, databases, utilities, software, etc. There are several problems with IoT cloud computing, including synchronization, standardization, balancing, reliability, and management. The extension of cloud computing services to the vicinity of users has improved efficacy with the assistance of fog computation. Fog computation includes characteristics such as location, distribution, scalability, support for mobility, interactive real-time services, and fly analysis [6].

5 v) IoT Application Software: Piece of code for the development of various industry-oriented applications. All services are provided for the same reason.

The IoT system can be used to target specific applications from household appliances, such as automated lighting, to medical science, to life-sustaining devices, such as a monitoring system for human heartbeat. IoT has been made highly accessible with the advent of technology and is used to produce big data, which is further used by Business Intelligence systems for decision-making objectives as shown in Figure 1.3.

1 i. Smart HomesWith thousands of people per month, the people graph searching for smart homes is growing exponentially. The most interesting thing is that several businesses and start-ups are included in Smart Homes for database analysis as shown in Figure 1.4. Prominent startup names such as AlertMe or Nest, as well as a variety of multinational companies such as Philips, Haier, or Belkin etc., are included in the list of startups.Below mentioned are some of the few application areas pertaining to Smart Homes, including monitoring of energy and water supply usage to receive guidance about how to cut costs and money, remote control appliances, detection of gaps and breaches of windows and doors in order to deter intruders, and control of conditions within museums and art warehouses [7–9].

2 ii. Smart CityOne of a city’s first steps towards being a Smart City is Smart Parking. It addresses a variety of problems related to parking, notifies drivers of available spaces, and when the parking period has expired. The diagonal smart parking garage has already been developed by China: a first of its kind robotic valet to move cars into a specific parking spot. It turns out that applications like waste control and water management are environmentally safe [10–13]. Figure 1.5shows a Smart City tracks the status of the parking areas in the city, monitors vibrations and material conditions in buildings, bridges, and historical monuments, detects Wifi and Bluetooth enabled devices, measures the energy radiated by cell stations and Wi-Fi routers, enhances driving and pedestrian overpasses, monitors surveillance of vehicles and sidewalk levels, manages intelligent highways with warning messages, and takes care of climate-specific diversions and unpredictable incidents such as collisions or traffic jams.

3 iii. Smart GridIn order to enhance the efficiency, economy, and reliability of the delivery of energy, a Smart Grid effectively promises to collect knowledge on the actions of customers and electricity distributors in an automated manner. Talking precisely over a state and country, both distribution and transmission systems aim at forwarding and collecting information from nuclear power plants, thermal power plants, Smart Houses, Cities, and Factories, electric vehicles, wind power plants, solar panels, etc. to and from the Smart Grid through grid specific applications [14]. They can prevent or minimize the damage natural catastrophes create, increase the efficiency of transmitting power, and reduce financial losses as shown in Figure 1.6. Figure 1.5 Smart city.
