  • Systems and methods for handoff in wireless network
    Patent number: 8442008
    Abstract: Methods performed by a mobile node (MN) in a secured network for handoff of communication from a serving access point (AP) to a target AP are provided. In a bounded delay channel switching (BDCS) method, the MN periodically switches between a first channel and one of multiple other channels during handoff, utilizes the first channel to transmit/receive packets to/from a corresponding node (CN) via the serving AP and utilizes one of the other channels to perform the handoff procedure to the target AP. In a dual-MAC switching (DMS) method, the MN employs a first MAC (medium access control) address to transmit/receive packets to/from the serving AP and a second MAC address to perform the handoff procedure to the target AP. The BDCS and DMS methods may be used concurrently, and may be used in a secured network that complies with, e.g., the IEEE 802.11, IEEE 802.1x or IEEE 802.11i plus IEEE 802.11f standards.
