Research on network selection algorithm of multi-network parallel transmission based on VIKOR

海上异构无线网络通信场景下,针对单一无线网络难以承载大带宽业务的现实问题,提出了一种基于VIKOR的多网并行传输网络选择算法。该算法首先将多个网络的参数聚合,筛选可用网络组合;然后,结合网络属性的主客观权重和用户偏好权重得到网络属性的综合权重;最后,根据VIKOR方法对网络组合进行排序,选出最佳网络组合方案。仿真结果表明:该算法具有可行性,相较于传统算法,在舰船通信业务繁忙情况下选网综合性能更优。

In the marine heterogeneous wireless network communication scenario,and aiming at the problem that it is difficult for a single wireless network to carry large-bandwidth services,a multi-network parallel transmission network selection algorithm was proposed based on VIKOR.The algorithm first aggregated multiple networks′parameter,filtered the available candidate network combinations.Then,the subjective-objective weight and user preference weight were considered in combination so as to obtain the comprehensive weight of network attributes.Finally,the optimal network combination was sorted by the VIKOR method.The simulation results show that the proposed algorithm is feasible and has better comprehensive performance than the traditional algorithm under the busy ship communication services.
