Abstract (in Japanese) (See Japanese page) 
(in English) Multi-hop wireless network which requires no infrastructure equipment such as access points is paid great attention in recent years. IEEE 802.11 DCF is generally used for MAC layer protocol and broadcast nature of RTS and CTS frames brings inefficiency of spatial usage in multi-hop wireless transmission. Directional antenna is one of the most promising ways of improving spatial usage of wireless channel. In multi-hop wireless networks, heterogeneous network configuration is general, which means each host is equipped with different network facilities. For antennas, it will be general situation that not all hosts are equipped with directional antenna. This paper proposes a new routing method which preferentially chooses directional antenna hosts as relay nodes. Our proposed routing method is based on AODV and a host equipped with omini-directional antenna broadcast received RREQ with probability which is adaptively determined by deployment of directional antenna. Simulation results show that our proposed routing protocol can improve throughput performance with maintaining connectivity of sessions.
