Reliability design and optimization analysis of marine ship internet of things monitoring topology

物联网在船舶中的应用对船舶航行的安全、管理和运行效率均具有重要意义。本文在分析船舶物联网分布结构的基础上,设计了基于九点基准监测面的监测系统拓扑结构,并对拓扑结构的参数进行量化分析。为解决簇头节点的失效问题,提出了冗余节点的策略,以船舶监测系统的可靠性为准则进行仿真试验,得出了船舶监测系统拓扑结构的最优参数。

The application of Internet of Things in ships is of great significance to the safety, management and operation efficiency of ship navigation. Based on the analysis of the distribution structure of ship internet of things(IOT), this paper designs the topology of monitoring system based on nine-point benchmark monitoring surface and quantitatively analyzes the parameters of the topology. In order to solve the problem of cluster head node failure, the strategy of redundant nodes is proposed. The simulation test is carried out based on the reliability of the ship monitoring system. The optimal parameters of the topology of the ship monitoring system are obtained.
