A Guaranteed Time and Rate Control Method for Improving QoS in WLAN

Abstract

Wireless Local Area Network is a mobile network, which connects the users in a small specific area. The devices within the area connect with each other through the wireless access points. The main requirements for the connection between the wireless devices are the time and the power. The transmission time between the wireless devices should be less and the power should be effective for the transmission to avoid the loss. With these considerations, we propose a novel method which hybrids the guaranteed time and power. The proposed method is designed for the network, which quickly responds to the slight changes and the normal networks. Guaranteed time slots are used for the time management and the rate control is used for the guaranteed power. This method works well in both the sensitive and insensitive areas. The performance of the proposed work is accurately analyzed using the analytical and the simulation methods. The numerical results obtained is accurate with the simulation results obtained using the ns-2.34 simulator. The throughput obtained is higher for the sensitive areas with minimum delay than the insensitive areas and closely matches the analytical results.
