Internet of Things (IOT): Introduction, Challenges, and Nowadays Research Directions

In this article, we examine the basic issues in IoT through recent studies focusing on this field, focusing on the entire concept of IoT, which has recently emerged as a new technology. If we need to define wireless communication today, it can be described as an intelligent and connected face that enables the integration of the global economy and strives to complete the concept of seamless connectivity anytime, anywhere, there is no doubt that the IoT ecosystem is in trouble from many problems. These challenges can be divided into two main categories; i. Common challenges include issues such as heterogeneity of communication, virtualization, and security. ii. In addition to specific challenges involving radio frequency identification and quality of wireless sensor networks, this article links general and specific challenges to demonstrate the use of IoT fear (Sachin Kumar in J Big Data, 2019).
