Abstract
A method and a wireless access point device for a network layer handoff of a wireless mobile node over a wireless local area network. The method includes detecting a wireless mobile node that has moved into the coverage area of the wireless access point device; maintaining an available IP address pool; selecting a temporary IP address from the IP access pool in response to the detection of the mobile node moving into the coverage area; and assigning a temporary IP address to the mobile node for use by the node during an interim period. The method produces a network layer handoff of a wireless mobile node over a local area network. Also provided is a computer readable article of manufacture tangibly embodying computer readable instructions for executing the steps of the method.
