摘　　要：为降低由于通信信道节点拥塞引起的通信效率较低的问题,提出考虑连续退避的网络通信功率均衡分配方法研究。建立通信网络模型,分析了信道上节点的运行状态,通过对其荷载状态进行计算,实现对超负荷节点的识别,根据识别节点的等待队列长度判断其退避动作的出现频率,以此为基础,对节点所需的功率调整值进行计算,并将计算结果分配到其对应的信道上,实现对信道功率的均衡分配。并进行实验测试,结果表明,所提算法能够将等待队列的长度控制在[61,91]范围内,稳定状态下拥塞避免系数为0.89,并将通信时延控制在5s以内,具有良好的通信效果。In order to reduce the low efficiency of communication caused by congestion of communication channel nodes,a method of power equalization allocation considering continuous backoff is proposed.The communication network model is established.The operation state of the nodes on the channel is analyzed.Through the calculation of the load state,the overload node is identified.The frequency of the retreat action is judged according to the waiting queue length of the identified node.Based on this,the power adjustment value required by the node is calculated and the calculation results are allocated to the corresponding channel,the equalization of channel power is realized.The experimental results show that the multi-channel algorithm can control the length of waiting queue in the range of[61,91],the congestion avoidance coefficient is 0.89 in stable state,and the communication delay is controlled within 5s,which has good communication effect.
