中文摘要	In this paper, we propose a distributed scheduling and optimization scheme (DSOQoS) for QoS guarantee in IEEE 802.11a based MANETs. In DSOQoS, for each station, the network layer takes different scheduling actions according to its local channel conditions estimated by the MAC layer, and the MAC layer takes different packet transmission actions based on the network load conditions estimated by the network layer. The optimizations are based on the following information sharing and interaction: traffic types, QoS parameters, network packet timeout periods, and the predicted packet transmission periods. We evaluate the scheme under different network loads and different station moving speeds. The simulation results show that DSOQoS can guarantee the QoS requirements in terms of packet delivery ratio, packet delay and delay jitter.
