摘要
提出一种用于Semi-TCP的基于被动侦听与数据帧调度的拥塞控制方法。该方法采用发送节点被动侦听周围节点发送的数据帧,量化节点活跃度来评估周围节点的拥塞程度,并以此来决定是否发送数据。仿真实验结果表明,该算法在不改变原有的MAC协议的情况下,使得未配置Semi-TCP功能的节点能和已配置的节点兼容,提高Semi-TCP的适用性,更快速地掌握网络的拥塞情况,及时进行拥塞控制,减少信道资源的浪费。
Proposes a congestion control algorithm based on passive interception and data frame scheduling.This method employs the sending nodes to listen to the data frames passively from neighbor nodes and quantifies the node activity to evaluate the degree of congestion of the surrounding nodes,then decides whether to send data.Simulation results show that,this algorithm makes the node which is not configured the function of Semi-TCP compatible with configured node,and improves the applicability of the Semi-TCP.It can grasp the congestion of network more quickly,complete congestion control timely,and reduce the waste of channel resources without changing the original MAC protocol.
