Abstract
A wireless network system that provides for seamless roaming of client devices is described. The wireless network system includes a plurality of access points. One access point is designated as the primary access point that is responsible for handling encrypted communication with the client device. The primary access point has access to the necessary encryption key(s) for encrypted communication. The primary access point receives broadcast updates from the other access points that includes connection scores. When a connection score for a second access point exceeds the connection score of the current primary access point, the current primary access point designates the second access point as the new primary access point and sends the new primary access point the encryption key(s) for encrypted communication. The handoff is seamless and does not require a new handshake between the new primary access point and the client device.
