Performance Enhancement of MAC Layer Protocol of WLAN using TDMA

In this paper, simulation and analysis the performance of existing MAC layer protocol and hybrid MAC with TDMA protocol in wireless local Area Network is presented. The demands of WLAN Devices day by day increases exponentially and it operates in the specific narrow spectrum of frequency bands and also increase communication parameters programmed and control over most modern wireless devices. In this simulation, we present a MAC protocol based on IEEE 802.11g standard in the DCF mode and DCF with TDMA mode which are useful to improve packet collision in traditional wireless networks. In this analysis, improved performance with TDMA base MAC layer is compared without TDMA. Here we used simulation through using NS-2 Simulator.
