In this paper, the authors are to achieve the energy efficiency in 802.11 WLAN through minimizing the energy consumption in the network. In this paper, they introduced a modification in DCF for enhancing the performance of WLAN and it is achieved by giving a new definition for the DCF function of transmission. Generally, in DCF the way AP transmits for the various nodes is one-way during the process of polling. The proposed function modification for DCF enhances the IEEE 802.11 standard DCF Multi-Way Transmission DCF Protocol (MWTDP) with an improved version MWTDP it gives a low-complexity mechanism by which the active and non-active stations in the BSS save energy during the process of polling.
