Abstract: An apparatus for assigning the bandwidth of a MOST synchronous channel and a method thereof are provided to enable various services to communally use the band assigned as one slot, by applying the subdivided bandwidth allocation method. A method for assigning the bandwidth of a MOST(Media Oriented Systems Transport) synchronous channel comprises the following steps of: requesting the bandwidth allocation of a corresponding node(S401); generating the bandwidth management table of the corresponding node(S402); transmitting information about the generated bandwidth management table to each node in the form of a message(S403); updating each node and a master by using the transmitted bandwidth management table(S404); and transmitting/receiving data between nodes correspondingly to the updated bandwidth management table(S405).

Abstract: A wireless sensor node is provided to reduce power consumption and lower the unit cost of a system by removing an MCU from an existing sensor node and integrating a hardware logic which performs only the same function with a sensor modem. A wireless sensor node comprises a sensor unit(210), a sensor controller(220) and a modem unit(240). The sensor unit performs a sensing function for acquiring information. The sensor controller is made of the hardware logic. The hardware logic collects the information, obtained from the sensor unit, generates an MAC frame, and manages a timer. The modem unit transmits standardized sensor data which is outputted from the sensor controller to a corresponding sink node. The sensor controller is designed together with the modem unit in the form of the one-chip.

Abstract: A channel assignment apparatus of an MOST network and a method thereof are provided to increase the number of times a channel is used and expand the bandwidth of the network. A channel assignment request of the first source node is received(S501). A master assigns the first channel to the first source node(S502). A channel assignment request of the second source node is received(S503). It is determined whether the data interference occurs between the first and second nodes(S504). If the data interference is not generated(S505), it is determined whether the connection overlap exists between the first and second nodes(S506). If the connection overlap does not exists, the first channel is duplicately assigned to the second source node(S507).

Abstract: A method for recovering and tracking a timing using a correlation value estimation window and a computer-readable medium having the program performing the functions embodying the same are provided to accurately recover and track the timing by changing the correlation value estimation window or a threshold value according to channel characteristics. An upper position and a lower position of a correlation value estimation window are limited to include a symbol position with a large correlation value based on a window of a preamble field(S110). The correlation value is checked after an upper limit of the correlation value estimation window reaches on a window corresponding to the preamble field, an FSW(Frame Start Word) field, or a CSW(Channel Start Word) field. It is determined whether the correlation value extends a threshold value(S120). When the correlation value is greater than the threshold value, the upper and lower limits of the correlation value estimation window are updated, and the next window is calculated(S130).

Abstract: An MOST(Media Oriented Systems Transport) gender and an MOST network using the gender are provided to use an MOST device by connecting a UTP(Unshielded Twisted Pair) cable when usage of a POF(Plastic Optical Fiber) used for configuring a network of the MOST device is restricted, thereby reducing an MOST network configuration cost. An O/E(Optical Electro) converter(210a) converts an optical signal which is a transmission signal of an MOST device(100) into an electric signal to send the signal through an electric cable. An E/O(Electro Optical) converter(210b) converts an electric signal into an optical signal for a receiving signal of the MOST device. A connector interface(220) sends the converted electric signal by connecting with the electric cable, and outputs the electric signal received from the electric cable to the E/O converter to input the outputted signal as the receiving signal of the MOST device.
