中文摘要：

基于IEEE802.16 Mesh网络,提出了一种拥塞控制策略。每个节点通过自身拥塞情况进行局部拥塞控制,同时利用节点间的协同能力在每相邻两跳内的3个结点间进行拥塞控制。通过跨层机制反馈整条传输链路的拥塞情况,并在链路源节点进行数据发送调节。仿真结果表明,这种基于跨层反馈的拥塞控制策略（CLFC2）能有效缓解链路拥塞状况,在负荷严重的情况下能提供更好的通信质量。

英文摘要：

Based on IEEE 802.16 Mesh networks,a novel congestion control strategy is proposed.On one hand,every node control congestion locally according to its congestion situation.Besides,congestion control is implemented among the three nodes in every two adjacent hops.On the other hand,the congestion situation of a link is provided by cross-layer feedback,then packet transmission is controlled at the source node.The simulation results show that this congestion control strategy based on cross-layer feedback（CLFC2） is effective for alleviating congestion,and can guarantee better communication quality in an overload network.
