Performance Evolution of MAC Layer in IEEE 802.11g Networks

Abstract—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. In general, IEEE 802.11 networks operate on either DCF (Distributed co-ordination function) or PCF (Point co-ordination function) mode. This research paper mainly focuses on PCF mode IEEE 802.11g standard and explains the necessity of amendment in terms of frequency, throughput, net bit rate, maximum indoor range and maximum output range. OPNET Simulator is used to calculate network load, throughput and medium access delay. Moreover, calculated performance metrics are compared with different user probability for IEEE 802.11g networks.

Index Terms—IEEE 802.11g, MAC, throughput, network load.
