Patent ID: 7664131

Claim:
A channel resource assignment method in a mesh Wireless Personal Area Network (WPAN), comprising the steps of: (a) transmitting beacons of all devices and adding an amount of channel resource to be reserved to the beacons so as to assign the channel resource for fair channel resource reservation between corresponding devices and adjacent devices when a mesh network is configured; (b) accumulating the amount of the channel resources reserved by all the adjacent devices except the corresponding device; and (c) determining the amount of the channel resources to be reserved by the corresponding devices using Eqs. 1 and 2 T others = ∑ j ≠ i ⁢ ⁢ T j Eq . ⁢ 1 T i =α( C−T others ) Eq. 2 where C represents a maximum size of a data transmit period (DTP) and is a sum of the DTP for reservation and a contention access period (CAP), and a is a rate factor, and wherein T others is a sum of a first reserved amount after the determined amount of the channel resources to be reserved by the corresponding device in a previous superframe and a second reserved amount before the determined amount of the channel resources to be reserved by the corresponding device in a current superframe.
