ENERGY EFFICIENCY IN IEEE 802.11 STANDARD WLAN THROUGH MWTDP

Anupam Das, Shikhar Kumar Sarma

Abstract: The main goal of this work is to achieve the energy efficiency in 802.11 WLAN through minimizing the energy consumption in the network. In this proposed study, we 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. With the inception of MWTDP transmissions are taken place in multi-way the access to the WLAN channel for mobile nodes in the list generated for polling with the SIFS interval whenever the transmission in receiving data packet from AP.
