Analysis of identifiers in IoT platforms

The Internet of Things(IoT) provides new opportunities for different IoT platforms connecting various devices together. The need to identify those devices is the foremost important to perform any kind of operation. Many organizations and standard bodies that provide specifications and frameworks for the IoT currently have their own identification mechanisms. Some existing industrial identification mechanisms can also be used in the IoT.There is no common Identification Scheme(IS) for the IoT as yet, because of the political and commercial differences amongst the standard bodies. The unavailability of a unified IS method makes the inter-working among IoT platforms challenging. This paper analyses and compares ISs used by several selected IoT platforms. This work will help in understanding the need for a common identification mechanism to provide inter-working among different IoT platforms.
