Our solution is based on an optimization approach which utilizes neural networks (NNs) to learn the cross-layer function. Simulations results demonstrate the effectiveness of our adaptation schemeAdaptive algorithmIEEE 802.11e wireless local area networks (WLAN)neural networks (NNs)quality of service (QoS).A Cross-Layer Adaptation Scheme for Improving IEEE 802.11e QoS by Learning
