ABSTRACT
The requirement for identity is adequately met in the networks, especially, given the emergence of ubiquitous computing devices that are mobile, and use wireless communications. IdM solution requires changes in the identifier format, and addressing mechanism. For IoT, it is envisioned that an incredibly high number of inexpensive pervasive devices surround us. Connecting all these devices to the Internet will involve the integration of multiple connectivity options based on the many designs, and deployment constraints. In IoT networks, normal things, or devices are a part of the whole network in order to collaborate, understand, and react accordingly as per the need. An identity is something which makes the thing distinguishable and delineate. Things under consideration only have one identity, but might be associated with many identifiers. An identifier discerns different users, places, or things within the context of specific namespace. The namespace plays an important role in defining an identifier because identifiers are always local to the current namespace.
