要約(英語): The ZigBee has attracted attention as the smart home network. Already the wireless LAN (WLAN) has been introduced in the home network. Both the ZigBee and WLAN use 2.4 GHz frequency band, and the carrier sensing mechanism is used for contentions, but the collisions are occurred because the access control procedure is different. Therefore, it is necessary to improve the transmission success ratio for the sensing data periodically sent by the ZigBee. This paper proposes a media access control for improving the transmission success ratio in coexistence environment between the ZigBee and WLAN. The point of proposal is the collaboration between the ZigBee coordinator and WLAN access point. When the ZigBee coordinator detects the signal for ZigBee, the access parameter, DIFS, for the WLAN is changed. Simulation results show the transmission success ratio is improved by reducing the collisions between the ZigBee and WLAN.
