Abstract: With the advent of the fifth generation (5G) era, many emerging Internet of Things (IoT) applications have emerged to make life more convenient and intelligent. While the number of connected devices is growing, there are also differences in the network requirements of each device. Network slicing (NS) as an emerging technology, provides multiple logical networks for infrastructure. Each of these logical networks can provide specialized services for different needs of different applications by defining its logical topology, reliability and security level. This article provides an overview of the basic architecture, categories, and life cycle of network slicing. Then summarized two kinds of resource allocation methods and security problems based on three kinds of network slicing technologies. With the investigation of recent studies, it is found that network slicing is widely used in Industrial Internet of Things (IIoT), Internet of Medical Things (IoMT), in-vehicle systems and other applications. It improves network efficiency, improves service quality and enhances security and privacy by optimizing indicators such as latency, resource management and service quality. At the end of this study, according to the challenges faced by different research methods, the future research direction of network slicing is proposed.
