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