基于加权网络状态评估的异构卫星网络多路径TCP数据调度算法

With the rapid development of multi-interface devices and mobile communication technologies, satellite networks will carry more network traffic requirements. The application of multi-path TCP (MPTCP) technology and the advantages of rapid deployment provide a powerful solution for the network bandwidth convergence and transmission efficiency of satellite networks. However, due to the large heterogeneity of heterogeneous network paths and the dynamic changes of environmental parameters, the existing data scheduling mechanism is not satisfactory. Therefore, based on the complex environment characteristics in aerospace heterogeneous networks, this paper improves on the basis of existing data scheduling algorithms, and proposes an MPTCP data scheduling algorithm based on weighted network state assessment for heterogeneous satellite networks. Weighted Network State Assessment Based Data Scheduling Algorithm, WNSA). The simulation experiment is carried out on the NS-3 network simulation platform. The results show that compared with the previous data scheduling algorithm, the throughput and transmission performance of the network are improved.
