Abstract:
PURPOSE: An energy sharing method of a wireless device and a device thereof are provided to share energy by maximizing application service time or life time in a wireless device. CONSTITUTION: A role determination unit(620) determines a role of a wireless device between an adjacent device and the wireless device. A transmission method determination unit(630) determines an energy transmission method for sharing energy between the adjacent device and the wireless device. A sharing unit(640) shares energy with one or more adjacent devices based on the energy transmission method. A transceiver(650) transmits energy or data to the adjacent devices and receives the energy or the data from the adjacent devices.

Abstract:
PURPOSE: An apparatus and a method for driving an adaptive operational program are provided to verify the implementation of an application by adaptively controlling the activation of an application program according to the state of a wireless channel or the state of a battery. CONSTITUTION: An application program module(310) includes at least one application program. A monitoring module(330) monitors the state of a wireless channel or the state of a battery. Whether a requirement for the application program satisfies the state of the wireless channel or the state of the battery adaptively controls the activation of the application program by a controlling module(350).

Abstract:
PURPOSE: A message exchange method of a hub device and a sensor node is provided to synchronize the protocol of the sensor nodes with the hub device including different protocols. CONSTITUTION: A super frame (100) comprises a beacon period (110), an access period (130), and a multiple access control (MAC) period (150). The beacon period transmits a beacon message including information related to a MAC protocol used in the MAC period corresponding to each sensor node or information related to an access period protocol used in the access period to the sensor node. The access period allows the sensor node to access a hub device according to the access period protocol. The MAC period transmits or receives data according to each sensor node or the MAC protocol corresponding to each sensor node.
Abstract:
단말기의 특성에 따라서 서로 다른 클래스의 프리앰블을 전송하는 데이터 전송 시스템이 개시된다. 데이터를 수신함에 있어 전력의 제한을 받는 단말기는 특정 클래스의 프리앰블만을 수신하여 에너지 소모를 최소화한다. 일반적인 단말기는 복수 클래스의 프리앰블을 수신하여 신속히 데이터를 수신할 수 있다.
Abstract:
PURPOSE: A data receiving device and data transferring device transmitting a data frame are provided to distinguish data frame by constellation mapping schema to each data frame through a data receiving device. CONSTITUTION: A constellation mapping unit(510) applies a first constellation mapping scheme to a first data frame. A transmitting unit(520) transmits the first data frame to a data receiving unit(540). The data receiving unit receives the first data frame. The data receiving unit receives a second data frame from a second transmitting device. The data receiving device distinguishes the second data frame and the first data frame according to each constellation mapping technique.
