| 摘 要： | 为了改进流媒体在无线多跳网络中的传输质量,提出一种TCP友好的拥塞控制算法.该算法考虑了MAC层的信道竞争,节点通过标记数据包来通知数据流它的竞争状态,数据流基于所估计的竞争状态来控制传输速率.仿真结果表明所提出的算法能更有效地利用带宽,与已存在的算法相比,有较高的吞吐量和较好的平滑性.

| Abstract: | A novel TCP-friendly congestion control algorithm was presented to improve the performance of streaming media service over wireless multihop network.The proposed algorithm has considered the channel contention of MAC layer,each ?ow controls its transmission rate based on the estimated contention state which each node noti?es to each ?ow by marking packets.Simulation results shows the proposed algorithm can utilize bandwidth more effectively,compared with existing algorithm,it has much large throughput and better smoothness. |
