Abstract: A method for managing semantic information on an M2M/IoT platform is provided. The method for managing semantic information according to an embodiment of the present invention stores semantic data in the first attribute of an M2M resource and updates a part of the semantic data stored in the first attribute. Accordingly, efficient management of semantic information on an M2M/IoT platform is possible, and particularly a partial update of the semantic information can be performed.

Abstract: A method for controlling wake-up of a sound wave-based wireless network and a wireless sensor network using the same are provided. A wireless device constituting the wireless sensor network is woken up by receiving a sound wave from an external device and receives data, or wakes up an external device by transmitting a sound wave and transmits data. Since wake-up is controlled by a sound wave through a microphone and a speaker which consume less power, a time that an RF transceiver spends staying in a reception standby state is minimized and power consumption at a wireless sensor node is minimized.

Abstract: A method for validating the validity of a group member of a virtual resource is provided. A method for validating the validity of a group according to an embodiment of the present invention obtains parent resource type information of a resource designated by a group member ID included in a group generation request and validates the validity of the group by using the obtained parent resource information. Accordingly, the validity of a virtual resource as a group member can be validated.

Abstract: An open M2M system and a method are provided. A method for managing resources according to an exemplary embodiment of the present invention includes: registering resources existing in a first domain at a second domain; and discovering metadata of a desired resource in the second domain. Accordingly, information management and sharing can be optimized, and registration and discovery of resources can be supported to be performed on a global scale.
