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。
In order to improve the network communications channel performance after the invasion of destruction, according to the network invasion damaged channel attenuation characteristics, adaptive bit and power division method, based on node reliability equivalent sub-channels improved attenuation channel communication network optimization method, the channel allocation scheme based on node credibility, the key link priority distribution channel, reduce link conflict, realize the preliminary optimization of network communication channel, again by the methods of equivalent to improve sub-chan-nels, on the basis of the channel has been destroyed by the invasion, when passed to the total number of bits must be based on sending power minimization model, comprehensive analysis of the characteristics of the same or similar sub-channels, decrease has been destroyed by the invasion of network communications channel signaling load, after the complete destruc-tion of network communications channel to optimize again. The simulation results show that this method can effectively re-duce the destruction of the network link conflict rate and data packet loss rate, improve the performance of attenuation net-work communication.
