| Abstract(in English) | Recently, the numbers of the mobile wireless LAN systems that are composed of mobile APs or tethering-smartphones and mobile terminals are increasing. This suggests the possibility that the channels for IEEE802.11 are not suitably assigned to the each LAN when many wireless LANs come closed each other. In order to obtain higher performance such as total throughput of the WLANs, the channel assignment is supposed to be a key technology. This paper explains basic rules of an optimal channel assignment. The assignment should be with considering both contention and interference in intra-channel and inter-channel interference. From the analysis of the contention and interference mechanisms, factors deciding effectiveness of performance degradation are described. Evaluations by using real APs and terminals showed that contention and interference severely affected total throughputs of all WLANs. Also, ACS(automatic channel selection) mechanism, which is equipped in almost all APs were shown to be never optimized for many WLANs. Instead of the ACS assignment, a small change from the assignment, based on the assignment rules, improved total throughput. |
