It was a material that clearly shows the effectiveness of the proposed method. What are the disadvantages of this proposed method?	There are two disadvantages on our proposed method. 1) We need to use TSF timestamp for microsecond-order synchronization. Nowadays, it is available at major wireless LAN modules. However, some modules don't support it. 2) Our proposed method can achieve fine synchronization among multiple nodes. However, it is on the relative time scale. If we want to precisely synchronize to the absolute time, we need to additional scheme to fix the compensated timestamps to the absolute time.
