Performance Evolution of MAC Layer in IEEE 802.11g Networks
The popularity of IEEE 802.11 networks comes with its low cost, high data rate and seamless handoff. With heavily utilized infrastructure based wireless networks, number of users are increasing rapidly which makes available unlicensed spectrum band more congested. Moreover, most of the IEEE 802.11 standards (b/g/n) operate on 2.4 GHz which has subject to interference with other services like Bluetooth, sensor networks and cordless phones. Hence, the performance of IEEE 802.11 MAC should be enhanced with respect to interference and spectral scarcity.
