Abstract: A method and apparatus for efficiently using a super frame in a distributed wireless network are provided. In a beacon period of a super frame, a beacon slot of a hibernation planning device is moved to the front of the beacon period such that a beacon slot that cannot be changed in a beacon period is prevented from being positioned at the back of the beacon period. In this way, all beacon slots in a beacon period can be adjusted and thus the length of the entire beacon period can be shortened; the length of a data transmission period can be lengthened; and the super frame can be efficiently used.

The network devices includes: a network device requesting a partner network device to send service information; and if service information of the partner network device is received, requesting a service to the partner network device based on the received service information.

Abstract: A wireless relay apparatus and method of extending a wireless communication range between a host and a device by relaying packets between the host and the device in a wireless universal serial bus environment. The wireless relay apparatus includes a management packet analyzing unit which receives a management packet including channel time allocation information and information related to the transmission direction of data and analyzes the management packet; a response packet analyzing unit which receives a response packet, which is a response to the management packet, from a wireless USB device and analyzes the response packet; a control unit which controls a stream of data between a wireless USB host and the wireless USB device with reference to the analyzed management packet and the analyzed response packet; and a transmitting/receiving unit which transmits or receives the management packet, the response packet, or data according to the result of the control.

Abstract: A wireless universal serial bust (USB) host, a wireless USB device, a method of providing the function of a dual role device host, and a method of performing the function of the dual role device. The wireless USB host includes a searching unit which searches whether a wireless USB device can create a beacon on the basis of a message received in a wireless USB point-to-point communication environment; a control transfer packet creating unit which creates a control transfer packet including beacon synchronization information, channel time allocation information, and information on a transmission direction of data on the basis of the searched result; and a transmitting/receiving unit which transmits the control transfer packet on the basis of the beacon synchronization information and performs data communication with the wireless USB device on the basis of the channel time allocation information and the information on the transmission direction of data.

Abstract: A method and apparatus for dynamically allocating an Internet Protocol (IP) address in a wireless network associates a wireless network device in a specified wireless network and sets an IP address by using an association value of a network ID of the wireless network and a logical address used to identify a wireless network device in the wireless network.

Abstract: A wireless network apparatus and method for performing channel allocation between heterogeneous wireless networks is provided. The wireless network apparatus includes a first ultra wide band (UWB) interface module that transmits and receives a frame compliant with a first UWB communication format; a second UWB interface module that transmits and receives a frame compliant with a second UWB communication format; and a channel time adjustment module that generates a transmission frame having channel allocation information, which is contained in a frame received through the first UWB interface module, reflected thereon and transmits the generated transmission frame through the second UWB interface module. The method includes receiving a frame compliant with a first ultra wide band (UWB) communication format; generating a transmission frame having channel allocation information reflected thereon; and transmitting the generated transmission frame according to a second UWB communication format.
