【摘要】：为了提高入侵破坏后网络信道通信性能,按照入侵破坏后网络信道的衰减特征,融合自适应比特以及功率划分方法,提出基于节点可信度子信道等效改进的网络衰减信道通信优化方法,采用基于节点可信度的信道分配方案,对关键链路优先分配信道,降低链路冲突,实现网络通信信道的初步优化,再通过子信道等效改进方法,在信道已经被入侵破坏的基础上,在传递总比特数一定时,依据发送功率最小化模型,综合分析特性相同或相近的子信道,降低已经被入侵破坏后的网络信道通信信令负荷,完成被破坏网络信道通信的再次优化。仿真结果表明,该方法可有效降低被破坏网络链路冲突率和数据丢包率,提高了衰减网络通信性能。
[Abstract]:In order to improve the communication performance of the network channel after intrusion destruction, the adaptive bit and power partition method is fused according to the attenuation characteristics of the network channel after the intrusion destruction.A network attenuation channel communication optimization method based on the equivalent improvement of the node confidence subchannel is proposed. The channel allocation scheme based on the node credibility is adopted to assign the channel first to the key link and reduce the link collision.To realize the initial optimization of the network communication channel, and then through the equivalent improvement method of the subchannel, on the basis of the channel has been destroyed by the intrusion, and when the total number of bits is fixed, according to the transmission power minimization model,By synthetically analyzing the subchannels with the same or similar characteristics, the signaling load of the network channel which has been damaged by the intrusion is reduced, and the re-optimization of the damaged network channel communication is completed.Simulation results show that the proposed method can effectively reduce the link collision rate and data packet loss rate and improve the communication performance of the attenuated network.
