The present invention relates to a method and to a wireless personal area network (WPAN) device in which the device sets the beacon slot in the WPAN device and receives beacon slot information from neighbor devices, while setting the beacon table of the devices, to avoid the transmission time of the neighbor devices and the transmission time of the devices neighboring the neighbor devices in a WPAN. In the method, beacon message, including information about neighbors' transmission time and information about neighbors' neighbors' transmission time, is received from neighbor devices. The beacon message is combined, and the neighbors' transmission time information and the neighbors' neighbors' transmission time information are input into a beacon table. The neighbors' transmission time and the neighbors' neighbors' transmission time are input into a field for BTTSs to be avoided in the beacon table. The first beacon slot is set, as my beacon transmission slot, among beacon slots except for the transmission time input into the field for BTTSs to be avoided. Information about the set beacon transmission slot is input into a field for my BTTS in the beacon table.

Method for allocating a beacon slot using a beacon table in wireless personal area network (WPAN) and WPAN device

The present invention relates to a method of efficiently assigning addresses in a WPAN and a WPAN device. The address assignment method of the present invention is performed by a higher device. Address assignment information for determining an address to be assigned to a lower device, is managed. An address is assigned to a lower device that requests connection from the higher device based on the address assignment information. The address assignment information is updated to a address value as the address value is assigned, and the updated address assignment information is transmitted to lower devices. If an update of address assignment information is requested by the lower device that assigned an address value to a device lower thereto, the address assignment information is updated and the updated address assignment information is transmitted to lower devices.
