摘要
为提高移动自组网的网络性能和推进Semi-TCP方法的实际应用,提出基于路由协议的Semi-TCP网络层逐跳拥塞控制实现方法.通过在网络层的路由协议中加入拥塞信息广播机制,控制节点对数据包的发送频率,保持链路高速传输数据的同时,降低拥塞程度.在EXata仿真平台进行了验证,在设计的动态拓扑实验中,文中方法的吞吐量相比TCP New Reno提高了 169.57％,在引入多TCP应用竞争链路后比原Semi-TCP方法提高19.52％,证明了文中方法的有效性.
Abstract
To improve the network performance of mobile ad hoc networks and promote the practical appli-cation of Semi-TCP method,a hop-by-hop congestion control implementation method based on routing proto-col for Network-Layer Semi-TCP is proposed.By adding congestion information broadcasting mechanism in the routing protocol of network layer,the sending frequency of data packets is controlled,which maintains high-speed transmission of data while reducing congestion.The proposed method is validated on the EXata simulation platform.In the designed dynamic topology experiment,the throughput of the proposed method is increased by 169.57％compared to TCP New Reno,and by 19.52％compared to the original Semi-TCP method after introducing competition between multiple TCP applications,demonstrating the effectiveness of the proposed method.
