Adaptive service differentiation for QoS provisioning in IEEE 802.11 wireless ad hoc networks

Published: 04 October 2004 Publication History

Abstract

The proposed scheme IEEE 802.11e draft standard defines new MAC protocol for QoS in wireless networks, namely HCF and EDCF. EDCF is a contention based channel access scheme and is part of HCF for infrastructure networks and may be used as a separate coordination function for wireless Ad-hoc networks. In this paper we propose to enhance EDCF with a dynamic traffic class's management protocol, which allows firstly, a guarantee of QoS to the sensitive applications some as the network state. Secondly, a sliding QoS differentiation between the Traffic Classes (TC) according to the instantaneous channels fluctuations. This sliding differentiation is based on a dynamic tune of the IEEE 802.11 MAC's parameters. The performances of the proposed scheme namely AMPA (Adaptive MAC Parameters), are extensively investigated by simulations. Results obtained indicate that AMPA scheme outperforms both DCF and EDCF.
