Abstract
The direction of movement of a wireless local area network client device, determined based on data generated by one or more sensors onboard the client device, is provided by the client device to its serving access point. Using the direction of movement information, a list is generated of neighbor access points that are likely to be in the path of travel of the client device. The list may be generated by the serving access point or another infrastructure device, e.g., a wireless network controller. The serving access point sends the list of neighbor access points to the client device to enable the client device to select an access point to roam to at the appropriate time.
