This document proposes a lightweight framework for efficient M2M device management in oneM2M architecture. It describes using CoRE Link format to represent M2M devices and endpoints, an architecture with a proxy layer to manage legacy devices, and phases of operation including registration, service enablement, and unregistration. The framework is designed to be flexible, scalable and support dynamic addition and removal of devices.

• Unique & novel aspect
– Allow management of legacy M2M devices.
• Current standardization efforts do not consider such scenarios but
inclusion of legacy devices into IoT ecosystems is crucial.
• The proxy layer is composed of two RESTful web services –
– Proxy-in to manage legacy sensors
– Proxy-out to manage legacy actuators.
• The proxy layer creates the CoRE Link based configurations and is
responsible for registering and un-registering legacy devices.
• The proxies are not dependent on the communication protocol
used by the legacy devices.

• Necessary to manage mobile devices.
• Based on a lifetime attribute
– Each device must announce itself or update its
configuration once during the lifetime.
– Otherwise the framework removes the
configuration.
– Value can be defined/modified by developers.
