| 摘 要： | 为提高船舶引航过程安全性,提出了一种基于智能航标(Intelligent Navigation Aid,INA)的近海边缘计算网络(INA-based Offshore Edge Computing Network,IOECN)架构,以提供助航信息保障。重点研究网络中网元节点的布局优化问题(Layout Optimization Problem, LOP)。通过数学建模,将LOP转化为整数线性规划(Integer Linear Programming,ILP)问题。在满足网络覆盖率及连通性条件下,以网络成本最低为求解目标,并使用Gurobi进行求解、运用Matlab进行仿真展示,最终得到不同规模下的网络优化方案,验证了模型的正确性及可扩展性。

| Abstract: | In order to improve the safety of the ship's piloting process, an INA-based offshore edge computing network (IOECN) architecture is proposed to provide navigation assistance information. The Layout Optimization Problem (LOP) of network element nodes in the network is mainly studied. The mathematical model is used to convert the LOP into an Integer Linear Programming (ILP) problem. On condition of the required network coverage and connectivity, aiming to minimize the network cost, being solved by Gurobi and simulated and demonstrated by Matlab, the network optimization on different scales is obtained and the correctness and scalability of the model is verified. |
