Preliminary Study of Bi-directional Data Exchange between OneM2M and LWM2M

Most Internet of Things (IoT) platforms may let one IoT standard be able to access another IoT standard's resources. This paper would survey and discuss how to achieve bi-directional data exchange between OneM2M and LWM2M. In other words, not only OneM2M can access the LWM2M resources like the existing works or specifications, but also LWM2M can be extended to access the OneM2M resources.
