Adaptive cross-layer resource allocation scheme resisting delay sensibility
抗时延敏感性跨层自适应资源分配方案*

In order to resist delay sensibility of real-time services,this paper proposed an adaptive cross-layer resource allocation scheme employing Hopfield neural networks(HNN) algorithm in multi-user OFDM system.In setting of the user scheduling priority,this paper considered not only the channel state information(CSI) at the physical layer,but also users' queue state information and waiting time at media access control(MAC)layer.By the HNN algorithm,the proposed scheme decreased the average delay and packet loss...
