Abstract: In order to mitigate the latency for channel handoff in wireless LAN, a novel channel handoff scheme named FCH-USRP is proposed. The FCH-USRP was based on the USRP equipped to provide timely and accurate wireless channel information for channel scan in wireless environment, thereby reducing the users channel switching delay. The experimental results show that the proposed scheme can effectively mitigate the delay of channel handoff and recover the interrupt data transmission in short time.

Key words: WLAN, channel handoff, USRP, time delay
