摘要
针对复杂电磁环境下的应用层网络编码方案,提出了一种有效利用多链路的优化传输算法。通过分析各链路的带宽、误帧率和绝对时延等指标,将多链路选择及负载分配问题建模成最优化问题,并通过标准线性规划方法找到最优解。仿真试验表明,基于网络编码的多链路优化传输算法可将网络编码数据包合理分配到各链路,从而实现端到端信息传输时延最小化。
For the application layer network coding scheme in complex electromaganetism environment,an efficient multiple link optimization transmission algorithm is proposed.By analyzing the bandwidth,frame error rate and absolute delay of each link,the multiple link selection and load distribution problem is modeled as an optimization problem,and the optimal solution is obtained through the standard linear programming.Simulation results show that the multiple link optimization transmission algorithm based on network coding can reasonably distribute the network coded packets to each link,so as to minimize the end-to-end information transmission delay.
