IoT and Internet 4.0
IoT based technology makes possible the integration of whole new idea of Internet 4.0 integrate smart manufacturing, in which process of data collection and data processing is done as accurately as possible by employing suitable sensors based systems. (Whitmore et al., 2015& Li, S. et al., 2015.

Need of Decentralization in IoT
The issue of efficient and trouble free working of smart devices deployed in Government and Corporate sector related Applications/Services is satisfactorily addressed by integrating decentralized applications.
dApp (Decentralized Application) thwarts any attempt to hijack the system as it involves the execution of software application on distributed multiple channels. Wheras, all the data is at stake, if someone hacks into the centralized servers. To overcome this threat, dApp is put into practice which makes it possible to maximize and replicate the transaction threads. In order to make dApp safer and user friendly, smart contracts are incorporated with dApp, which makes Dynamic Token sharing as a mandatory feature/step while completing the transaction. Not only does this smart contract based dApp enhance the security of transactions , but also makes it possible for people hailing from different countries with different languages to make transactions conveniently anywhere in the world.

Systematic Review Methods
The review methods in the methodical aspects are having diversified key points with the direct addressing to the IoT based technologies. The review is done after extraction of assorted manuscripts and the research articles from multiple sources including Web of Science and related high citation sources of research. (Souri et al., 2019)

Execution Plan
The execution plan contains five steps: (i) Search manuscripts from various portals; (ii) Repeated manuscripts are excluded; (iii) Select manuscripts on pre-defined criteria; (iv) Data extraction and quality assessment; (v) Meta analysis (Souri et al., 2019 andBrous et al., 2020). Furthermore, this manuscript used the following this manuscript used the following electronic databases to find the papers (as shown in Figure 2). Following is the integration of word cloud from the assorted manuscripts and found that there are huge elevations and association of the IoT based technologies in the manuscripts focusing on the sensor technologies (as shown in Figure 3).

Results
This methodical analysis of the research manuscripts is having the multiple dimensions and research questions which are addressed henceforth with the analytics patterns. RQ1: Which are the recent trends and technologies in the allied domains? The recent trends are classified into six themes ( The implementation process of e-governance includes the following: (i) GBPR (Government Business Process Re-engineering) -it changes to the already existing procedure to make it more efficient with the help of their services like, online tracking process. Eg: online application submission requesting for Birth certificate; (ii) EB (Electronic database) -It involves the digitizing of data that is involved with the government such as government records, tenders etc. (Cheng et al., 2018 and) (iii) Traffic and Smart Transportation: Mobility and intelligent transportation systems (ITS) takes advantage of technologies like IoT and big data analytics to manage traffic and mobility in smart cities. It provides improved interfaces that enhance transport infrastructure and transport services. An ITS includes: (i) Creating different interconnected transport systems integrates communication between devices and vehicles; (ii) It provides the direct access of real time information about transport condition (Masek et al., 2016;Sivanathan et al., 2017 andPark et al., 2018).

(iv) Sustainable Energy, Power and Environment
Monitoring: For renewable energy sector, IoT is one of the main key components in the next growth stage. Smart energy solutions are surely a better approach than the already existing non-renewable resource that produces harmful gases. An application of IoT alleviates many challenges that are limiting the acceptance of renewables. Some of the IoT applications in renewable energy are: (i) Smart grids for enhanced renewable implementation; (ii) Automation to improve the overall production (Masmoudi et al., 2017 andBibri, 2018). (v) Internet of Everything (IoE) and Nano-Things: IoT is composed of things only but the IoE is built on four pillars (data, people, process and things). IoE has the potential to extract real time data from million and billons of sensors that are connected to it. The IoT is being extended by the implementation of Internet of Nano Things. The different functional task like sensing or actuation is done by nano machine in IoNT (Miraz et al., 2015;Clarke, 2013 andAbdelwahab et al., 2014). (vi) Telemedicine / Smart Healthcare IoT has transformed the arena of healthcare by yielding continuous health monitoring services very important feature of IoT in smart devices to connect the different health apps for tracking the patients health and to ensure their compliance. Telemedicine is remote monitoring of the patients who are unable to visit doctors due to the age, distance or other unavoidable reasons etc., so this technology provides virtual healthcare assistance helps people located in remote areas or the ones who are unable to visit the doctors and hospitals due to factors like distance, age, or busy lifestyle. (Aniza et al., 2017;Baker et al., 2018;Chau et al., 2002 andDahri et al., 2017).  (i) Proximity Sensor (used in retail industry to detect motion and correlation between the customer and product) (ii) Pressure Sensor (used for the maintenance of water systems and heating systems) (iii) Gas Sensor (used to detect the quality of air and level of different gases present in the air) (iv) Water quality Sensor(used for monitor the quality of water for different purposes like pH sensor, Chlorine Residual Sensor) (v) Humidity Sensor (used to detect amount of water vapour in an atmosphere of air) (vi) Motion Detection Sensors (used to detect the physical motion or movement of any object or human beings) RQ4: Which key points are mandatory to be analyzed with Internet of X (IoX)? Here X refers to Things, Objects, Clouds, Everything Inderpreet Kaur & Kamaljit Singh Saini, J. Technol. Manag. Grow. Econ., Vol. 11, No. 1, April 2020 Identification of Motes, Design and Architecture, Networking, Standardization.
Identification of Motes: A mote (short form for Remote) acts as a remote sensor is a wireless transceiver that has the ability to log onto a network from a remote or distant location. Motes in IoT are IP-enabled and thus are provided with an IP addresses (6lowPAN) allowing them to interact with remote nodes in an end to end way. Contiki OS implements a lightweight IP stack into classical WSN nodes e.g. MICAz, Tmote etc. Crossbow MICAz can be widely used in monitoring as well as security purposes. The MICAz software consists of two software components-Moteworks and Moteview. Mote-Works based on TinyOS operating system, it is being used for the development of custom sensor applications. Mote-view it works as intermediate between users and the network. Mote-view is used and has the capability of displaying and analyzing the data collected by the motes.
Design and Architecture: The architecture of IoT contains very large number of elements like protocols, actuators, sensors, cloud services and different layers. The design architecture of IoT has four different stages: (i) IoT network protocols (actuators and sensors); (ii) Data acquisition systems and internet gateways; (iii) Analytics and pre-processing; (iv) Analysis, management and storage of data.
Networking: WSN (Wireless Sensor Network) is a collection of distributed sensors that monitors environmental conditions like pressure, sound and temperature. WSN plays an important role in IoT by using communication technology. For the connectivity requirements for IoT, a single technology cannot meet all the requirements like range, power, size and cost etc. If your IoT network is local and limited to M2M (Machine to Machine) then 6LoWPAN, DASH7, Wireless M-Bus, Z-Wave and SA100 are the good candidates. But if you want to transfer data over internet then IPV6 (Internet Protocol Version 6) is the right choice.
Standardization: IoT standardization is an important key to reduce the cost of data; to reduce the cost of manufacturing individual components; to reduce transport cost; to reduce the gaps between protocols. (ii) Interoperability: It is a important feature for communication between smart devices, IoT applications and cloud providers. The main challenges in this area are scalable architecture to interact with data center and smart things. (iii Trust and access control: It is an important key challenge to increase. For safe data delivery, trust management can be very effective in smart things and IoT. Moreover; can be an influential factor between smart devices and IoT for trustable communication. (iv) Energy consumption: The various IoT devices such as sensors, mobile agents, and wireless technology are physically interacted with the IoT applications. These IoT applications have more energy efficient when we compare these with centralized topologies. Moreover, achieving industry 4.0 is not an easy as it faces many difficulties and challenges.eg. technological, scientific and economical.

Final Considerations
From the voluminous and diversified literature analysis, it has been found that the factors for comparing quality of service with the performance parameters are the key points in the research domain of IoT. The analytics from the research portals and manuscripts show that the performance and availability of the sensor technologies are highly addressed with the overall effectiveness so that the real and efficiency-aware adoption of IoT can be done for multiple applications in the real world.
