Energy Efficiency in IEEE 802.11 standard WLAN through MWTPP
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 1
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 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. With the inception of MWTPP 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.
