摘要
对通信信号多路径传输信道进行实时分配能够保证通信信号的传输速度以及通信质量。针对当前通信信号多路径传输信道实时分配方法在信号传输的过程中,存在的数据丢包率较大,信道负载均衡性较差,以及信号传输速度慢问题,提出一种基于博弈论的通信信号多路径传输信道实时分配方法。根据信号传输过程中,节点干扰和信道的传输速度的影响,确定通信信号多路径传输信道实时分配的目标函数,并利用博弈论中对纳什均衡性求解的一般算法对目标函数进行求解,将通信信号多路径传输成功率作为通信信号传输的效用函数,构建通信信号多路径传输信道实时分配模型,实现信道分配。实验结果表明,所提方法分配的通信信道,实现信号传输的速度较快,且信号传输过程中,丢包率较低,信道的负载均衡性较好。
A method to distribute multi-path transmission channel of communication signal in real time based on game theory was proposed. According to the node interference and the influence of transmission speed of channel, the objective function of real-time allocation of multi-path transmission channel of communication signal was determined. Meanwhile, the general algorithm for solving Nash equilibrium in game theory was used to solve the objective function. Moreover, the success rate of multi-path transmission of communication signal was used as utility function of communication signal transmission. Finally, the real-time allocation model of multi-path transmission channel for communication signal was built. Thus, the channel allocation was achieved. Simulation results show that the communication channel allocated by proposed method achieves the faster signal transmission. Meanwhile, the packet loss rate is low during the signal transmission and the load balance of the channel is good.
