Abstract (in Japanese) (See Japanese page) 
(in English) As an access network to the Internet, we have studied the Wireless Internet-access Mesh NETwork (WIMNET) that is composed of multiple access points (APs) connected with wireless links. Because most traffics pass through the gateway (GW) to the Internet, the links around the GW are crowded which should be activated with higher priorities in WIMNET. In this paper, we propose the fixed waiting time switching method based on the CSMA/CA protocol (CSMA-FWS) to improve the performance of WIMNET. Before communications, the target link activation rate and the fixed waiting times for link activation/waiting are calculated from expected traffics of each link. During communications, these waiting times are switched by evaluating the link activation rate. Besides, by assigning different values to these waiting times among the links, the conflicts among interfered links are avoided. Through simulations using two types of network topologies, we verify the effectiveness of our proposal.
