Abstract (in Japanese) (See Japanese page) 
(in English) Since a wireless mesh networks (WMN) is operated by using multi-hop communication with wireless lan nodes, it can be introduced easily and in low cost. Since communications between MNs (Mesh Nodes) are received radio disturbances from the each other neighbor communications, the space use efficiency falls. The influence of radio wave interference is reduced by using a directional antenna, and improvement in space use efficiency is expected. However, directional hidden terminal problems and deafness problems occur. Although technique which is over comming these problems was proposed as an existing research, the overhead in round transmission of a directional antenna increases. In this research, the number of times of round transmission is reduced by using relay nodes, and also a new directive mac protocol which can reduce the influence of directional hidden terminal problems as well as deafness problems is proposed.
