Abstract
Provided is a probing method for handoff including constructing a group of neighbor access points of a current access point with which the station associated, generating subgroups of the neighbor access points by the channel assigned to the access points, probing the access points by subgroup in a subgroup selection order, and selecting the neighbor access point having best link quality as a target access point to handoff. The probing method of the present invention is implemented with a novel non-overlap graph for constructing the neighbor graph such that the probing latency is dramatically reduced, resulting in reduction of handoff delay.
