针对无人船航行环境复杂，导致无人船异构通信网络通信质量较差的问题，研究决策树算法在无人船异构通信网络切换中的应用。选取信号强度、最大传输速率以及误码率，作为无人船异构通信网络切换的网络属性，设置各网络属性作为C4.5决策树算法的决策节点，C4.5决策树算法选取信息增益率作为属性分类标准，构建候选网络集。归一化处理候选网络集内的通信属性值，获取各通信网络的多属性判决值，选取具有最大多属性判决值的网络，作为目标网络，完成网络切换。实验结果表明，该方法有效切换无人船异构通信网络，切换后网络吞吐量高于50 Mbps。
Aiming at the problem of poor communication quality of heterogeneous communication network due to the complicated navigation environment of unmanned ship, the application of decision tree algorithm in the switching of heterogeneous communication network of unmanned ship is studied. The signal strength, maximum transmission rate and bit error rate were selected as the network attributes of the unmanned ship heterogeneous communication network switching, and each network attribute was set as the decision node of the C4.5 decision tree algorithm. The C4.5 decision tree algorithm selected the information gain rate as the attribute classification standard to construct the candidate network set. The communication attribute values in the candidate network set were normalized to obtain the multi-attribute decision values of each communication network. The network with the most attribute decision values was selected as the target network to complete network switching. The experimental results show that this method can effectively switch the heterogeneous communication network of unmanned ship, and the network throughput is higher than 50 Mbps.
