摘　　要：基于甚高频数据交换系统(VHF Data Exchange System,VDES),通过分析海上真实船舶运动特征,提出一种符合船舶移动特征的移动模型——船舶平滑转向的高斯马尔可夫移动模型。针对性地研究了不同船舶节点密度环境中的自组织网络路由协议,仿真分析了不同自组织网络路由协议应用于VDES时的数据传输性能。结果表明,按需距离矢量(Ad Hoc on-demand Distance Vector,AODV)路由协议明显优于其他路由协议,可将其作为VDES下船联网系统最优路由选择方案。Based on the VHF Data Exchange System(VDES),this paper proposes a ships smooth swerve Gauss-Markov mobility model which in line with the ship motion feature movement model by analyzing the motion characteristics of real ships at sea.The self-organizing network routing protocols in different ship densities were studied.The data transmission performance of different Ad Hoc network routing protocols applied to VDES was simulated and analyzed.The results show that Ad Hoc on-demand Distance Vector(AODV)routing protocol is obviously superior to other routing protocols,which can be the optimal routing scheme for VDES disembarking network system.
