In recent years, the IEEE 802.11 based wireless LANs (WLANs) have gained great popularity. The WLAN uses the two mechanisms to access the medium in 802.11 distributed coordination function (DCF) and point coordination function (PCF). To improve the PCF large work is performed by different researchers and new methods were proposed. In this work the Improved BDPCF algorithm is proposed to enhance the WLAN. The scheme is designed and implemented. The results are obtained by performing different experiments. The obtained results are analysed.
