In order to solve the problem that classifying mechanism of SFB congestion control algorithm for wireless sensor network could be influenced to cause transmission performance degradation of TCP flow under large network flow,the paper introduced algorithm implementation of an integrated congestion control mechanism,and did simulation research of performance of the mechanism by use of NS-2 platform.The mechanism solves congestion by establishing a new path to distributing data packets.When the new path is not...

0引言在无线传感器网络中,拥塞会导致信道质量退化,损失率上升,延时增加,造成网络节点负载数据遍历不均衡,因此需采用适当的拥塞控制算法解决拥塞问题。在现有的无线传感器网络拥塞控制算法中,TD(Tail Drop)算法的基本思想是在产生拥塞时丢弃到达的包。RED(Random Early Detect
