Abstract

WLANs, due to the characteristics of the wireless medium, exhibit time and location dependent features. The ability to adapt to such conditions and enable optimal behavior is a key issue in future generation heterogeneous networks where WLANs are envisioned as an integral part. This paper uses a recently derived analytical model of the throughput performance of non-saturated contending IEEE 802.11a systems under fading conditions which is extended in order to define a novel, cross-layer based, throughput improvement MAC FEC scheme for IEEE 802.11a links.
