Resumen
The European Telecommunications Standards Institute (European Telecommunications Standards Institute or, in short, ETSI) is an independent, non-profit organization for standardization in the telecommunications industry. ETSI has successfully standardized the GSM cellular communication system and the TETRA professional mobile radio communication system. ETSI is one of the founders of 3GPP. This article discusses ETSI's Internet of Things (IoT) initiatives. In particular, the oneM2M standard, which uses a simple horizontal platform architecture, is considered. This architecture fits into a three-tier model that includes applications, services, and networks. At the first of these layers, application objects (AEs) are located in separate applications of devices and sensors. They provide a standardized interface for managing and interacting with applications. Shared Service Objects (CSEs) play a similar role at the service level, which is between the application layer and the network layer. The network layer ensures that devices, sensors, and applications can operate independently of the network.
