| Abstract(in English) | IEEE 802.11a, one of the Wireless LAN systems, communicates utilizing a common frequency spectrum with IEEE 802.15.3a, one of the Wireless PAN systems. Therefore, in the coexistence environment, the WPAN signal power affects the carrier-sensing of WLAN. As a result, the throughput of the latter degrades. In this paper, the transmission power of WPAN is controlled to avoid interference to WLAN. By using cognitive radio technique implemented at the base station of WLAN and monitoring throughput of WLAN, the transmission power is controlled accordingly. Additionally, the value of each transmission power is optimized with priority in order to maximize total throughput of both WLAN and WPAN. In the performance evaluation, each throughput and carrier-sense error rate are calculated and compared. |
