In this paper, we propose a new Medium Access Control (MAC) protocol, Intra-class Fair Medium Access (IFMA) which offers intra-class fairness enhancement in infrastructure-less wireless networks. Our approach is based on adjusting one of the contention parameters in the Medium Access Control (MAC) layer, known as Arbitrary Inter Frame Space Number (AIFSN) in IEEE 802.11e standard, with respect to an easily obtainable measure related to packet loss statistics of individual users. Through rigorous simulations in ns-2, we show that our approach allows individual users in each QoS class to share the channel in a fair manner.
