摘　　要：无线传感网络中节点数据流量较大,分布范围较广,节点选择寻优计算复杂,导致浪费大量算力在节点选择上,拥塞控制效果不佳。提出一种无线传感网络拥塞控制中节点选择强制博弈方法,计算单条网络链路传输成本,依据传输数据耗费能量,计算传输节点可用能量比值,在传输变量权重值基础上,求得传输节点实际拥堵指数,完成节点选择。计算网络连接层的数据包丢弃概率,确定网络拥塞程度,汇聚节点数据流建立节点选择强制博弈模型,明确传感网络稳态传输条件,利用流量正态分布算法,在节点选择博弈中做出强制选择。经仿真分析证明:所提方法分组递交率保持在83%以上,丢包数量保持在100 pkt/s之内,网络传输节点端到端的延迟在0.3 s以内。In wireless sensor network,the node data traffic is large and the distribution range is wide,and the node selection optimization calculation is complicated,resulting in wasting a lot of computing power in node selection,and the congestion control effect is not good.A forced game method for node selection in congestion control of wireless sensor networks is proposed.The transmission cost of a single network link is calculated.According to the energy consumption of transmission data,the ratio of available energy of transmission nodes is calculated.On the basis of transmission variable weight value,the actal congestion index of the transmission node is calculated,com-pleting.The packet drop probability of the network connection layer is calculated,the degree of network congestionis determind,and a node selection mandatory game model for the aggregation node data flow is established.The steady-state transmission conditions of the sensor network is clarified,and the traffic normal distribution algorithm is used to make mandatory selection in the node selection game.The simulation analysis proves that the packet delivery rate of the proposed method is kept above 83%,the number of lost packets is kept within 100 pkt/s,and the end-to-end delay of network transmission nodes is within 0.3 s.
