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.
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.
