The Internet of Things (IoT) is a way to address and communicate with objects and their virtual representations. The exponential development of Smartphone, tablet, sensors and their applications has created very complex systems. From here, the concept of M2M (Machine-to-Machine) has emerged to provide communication and service architecture without human intervention. The European Telecommunications Standards Institute (ETSI) has proposed a horizontal architecture that can fit to several domains: transport, energy, e-health, etc. A crucial aspect is the management of devices in a system where equipment can be used during decades. Several protocols exist, in this article we explain the OMA DM management protocol, and we describe its connection to the ETSI-M2M platform. An extension of device management is proposed with an autonomic capability.
