• I confirmed that this test-bed actually achieved smooth internet access in the case that the communication hops three times in MANET.

Evaluation (Handoff time)
• Performance metric : Handoff time• MS1 sends ICMP packet to MS2 by Ping, while moving.• MS1 deassociate from AP1 and associate with AP2.• The time of communication blackout was measured.

Conclusions
• Conclusions– We designed and implemented M-WLAN.
• We constructed a Mesh Network -802.11 a/b/g standard was used. -L-2 function was left unchanged.
– We evaluated the performance of M-WLAN in our test-bed.• We presented
- the capability of M-WLAN. - a possible solution to the cause of lower performance.
