Energy Efficiency in IEEE 802.11 Standard WLAN through MWTPP

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.
