A channel splitting scheme is proposed to improve both link and network-layer handoffs in WMNs. The authors first considered two setups when an MC has one or two transceivers and proposed different handoff procedures using the channel splitting strategy. In the first design, the time for the link-layer channel scanning process can be reduced, whereas in the second design, the handoff process and data reception can be executed at the same time. In both designs, the channel contentions between handoff signaling packets and data packets at each MR are eliminated.
