摘　　要：针对传统船舶网络通信最优路径的规划方法存在的误码/丢包率高、数据传输时延长的缺陷,提出船舶无线网络通信路径最优规划优化方法。结合船舶无线网络的通信原理,构建相应的物理结构,并确定通信的起点和终点位置。在此基础上生成多条通信路径,对其进行计算,并从带宽、部署成本、时间开销等多个方面设置约束,在多约束下得出船舶无线网络通信路径的最优规划结果。通过与传统规划方法的对比得出结论:设计规划方法得出的最优通信路径的误码率和丢包率分别降低了2.12%和0.51%,且数据传输速度得到有效提升。Aiming at the defects of low success rate of data transmission and prolonged data transmission in the current planning method of the optimal path of ship network communication,an optimal planning and optimization method of ship wireless network communication path is proposed.Combined with the communication principle of ship wireless network,the corresponding physical structure is constructed,and the starting point and end point of communication are determined.On this basis,multiple communication paths are generated and calculated,and constraints are set from bandwidth,deployment cost,time overhead and other aspects,and the optimal planning results of communication paths in ship wireless network are obtained under multiple constraints.Compared with the traditional planning method,it is concluded that the bit error rate and packet loss rate of the optimal communication path obtained by the design planning method are reduced by 2.12%and0.51%,respectively,and the data transmission speed is effectively improved.
