Method for handoff in a wireless network
Abstract
A method enables access points to support a handoff for at least one station in a wireless network. The wireless network includes the access points for covering constant service areas and the station associated with the one of the access points for receiving communication service. The method comprises generating a neighborhood graph configured by handoff-capable neighboring access points; receiving information including context of a station propagated from a prior access point of the station, the prior access point being one of the neighboring access points; and propagating information including the context corresponding to the station to the neighboring access points of the neighborhood graph in response to association or re-association with the station using the received context.
