Abstract(in English) | Recently, due to remarkable progress in wireless communication technology, various wireless networks are becoming more available in many situations. However, the characteristic of wireless environment causes many problems like limited bandwidth, collisions and interferences of transferred frames. It is required to enhance bandwidth with effective channel utilization by minimizing the problems. In this paper, in infrastructure type wireless LAN, we achieve higher communication throughput with minimum increase of hardware complexity. Specifically, we increase bandwidth by introducing multi-channel environment where a base station has multiple transceivers and each of them uses a dedicated wireless channel. Moreover, in order to minimize collisions and interferences caused by hidden terminal problem, the base station controls the operation channel of each wireless station equipped with one transceiver. This proposal increases communication throughput and its fairness between wireless stations. Finally, we show the effectiveness of the proposed method by computer simulation. |
