However, Chin, Callaghan and Allouch (2019) provided the focus on the application of IoT for consumer electronics in the future. The author stated in the literature that IoT assists in the enhancement of user experience along with the satisfaction of customers on an immediate basis by providing them with a convenient way of living in their everyday lives. IoT further assists in collecting data of consumers in an efficient manner and further provides an allowance to the producers for the purpose of analyzing and optimizing the utilization of the devices and applications.

Challenges Related to IoT

Reyna et al. (2018) highlighted the challenges that will be faced by IoT in the future. Technology is considered the major challenge that will be faced by the application of IoT in the future, such as connectivity, security, standards, longevity as well as compatibility. Social and legal are other challenges that will be faced by the application of IoT in the future. Privacy and regulatory standards will be the major concern for the areas making use of IoT in the future (Tang et al. 2019). However, there are several mitigation measures in order to avoid the challenges that will be faced in terms of the application of IoT in the future.

The research methodology that has been taken into consideration for the research paper is secondary research. All the data that has been gathered are from a secondary sources such as the existing research papers along with journals as well as articles. The data analysis technique which has been utilized is the qualitative data analysis technique (Stobaugh et al. 2019). All the data that will be collected through the secondary sources will be interpreted and evaluated for taking into consideration in future research. The secondary data are not collected directly from the sources, and the research work of other authors will be interpreted for utilization in this research. Therefore, in order to avoid the problem of data restrictions, all the data that will be collected from the research work of other authors shall be referenced and cited in order to avoid the problem of plagiarism (Jena and Kar 2019). Anyone can undertake the collection of secondary data, and as a reason, the secondary research method has been taken into consideration.

The different limitations that are related to this research include the availability of relevant data. Restriction of data is regarded as the major problem because there are few relevant papers whose access is denied, and the same requires the approval of the author (Lee, Kim and Desta 2020). In addition to this, time is regarded as another issue for the research because the time provided for research was limited, and several activities associated with research were to be undertaken to complete this research in a successful manner.

From the research, the result that has been gained is about the existing utilization as well as application of IoT. Furthermore, future applications related to IoT have been gained along with the challenges that are faced at the time of using IoT. The existing trends associated with IoT that have been achieved from the research include the utilization of IoT for the purpose of security in organizations (Mei et al. 2019). In addition to this, IoT has assisted in fuelling the 5G technology, and this further revolutionized the growth in terms of technology. The utilization of blockchain technology is regarded as another existing application of IoT. There are several artificial intelligence applications that are enabled by IoT, and the usage of IoT and artificial intelligence together is said to be useful for providing commercial solutions. A very less amount of data is required at the time of using algorithms associated with AI, and therefore, its existing use is vast.
