摘　　要：对网络通信信息传输效率的控制,能够有效提升网络通信的质量。对信息传输效率的控制,需要根据节点的度量值选择下一跳传输节点,给出信息传输效率控制约束条件,完成对信息传输效率的控制。传统方法组建网络通信中信息分流传输路径,给出路径拆除阈值,但忽略了给出信息传输效率控制约束条件,导致控制精度偏低。提出基于区间数的网络通信中信息传输效率控制方法。采用复杂网络理论给出信息传输关系模式,将网络通信中信息传输关系分为不同的阶段,计算出正确收到一个数据包而请求重传的次数,将节点传输水平、距离原路径跳数及信道占用率作为选择下一跳节点的依据,根据节点综合度量值选择下一跳传输节点,给出对信息传输效率控制约束条件,完成对网络通信中信息传输效率控制。仿真证明,所提方法控制精度较高,为保障网络通信的稳定性和准确性奠定了基础。This paper proposes a control method for information transmission efficiency in network communication based on interval number. First of all, we gave a relational model of information transmission by adopting complex network theory to divide information transmission relationship in network communication into different stages, and cal- culated the number of request retransmission when a data packet was received correctly, and then selected node trans- fer level, distance path hops and channel occupancy as basis of next hop node. At last, according to node integrated metric, we selected transmission node of next hop to give control constraint condition for information transmission efficiency and completed efficiency control of information transmission in network communication. Simulation results demonstrate that the method in this paper has higher control accuracy and can ensure stability and accuracy of net- work communication.
