Abstract
The rapid development of technology currently revolves significantly around Internet of Things (IoT) and expected to play an important role in coming days. IoT has become the focus of attention for many researchers to discover issues and challenges that related to its design and architecture. One of the many significant issues is the multitude of languages, protocols and standards, as well as the lack of agreement on which it works best for individual layers of the IoT. It does not have a single platform of standardization; it is changed due to the heterogeneity of connected things. This paper discusses Lack of Standardization issues, challenges and review existing state of the art standards to highlight and overcome it by presenting some technical solutions.
