METHOD FOR ALLOCATING AN ADDRESS OF DEVICE IN WIRELESS PERSONAL AREA NETWORK (WPAN) AND WPAN DEVICE
First Claim
1. A method of efficiently assigning addresses in a Wireless Personal Area Network (WPAN) supporting a tree structure, the method being performed by a highest device, comprising:
- a first step of managing an address assignment information, for determining an address to be assigned;
a second step of assigning an address based on the address assignment information to a lower device that requests connection;
a third step of updating the address assignment information as the address of the second step is assigned, and transmitting the updated address assignment information to lower devices; and
a fourth step of, if an update of the address assignment information is requested by at least one of the lower devices that assigned an address to a device lower thereto, updating the address assignment information, and transmitting the updated address assignment information to the lower devices.

Abstract
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.
