摘　　要：移动Ad Hoc网络的连通可靠性对于战场的指挥控制、警察与医疗部门的抢险救灾等众多领域具有重要意义。然而当前的移动Ad Hoc网络连通可靠性评估方法大多建模简单,考虑因素单一,而以OPNET为代表的网络仿真只针对网络普通性能分析而没有可靠性分析。因此,目前缺少一种能够涵盖真实场景中节点移动、无线通信特性和复杂地形环境的移动Ad Hoc网络连通可靠性评价方法。针对此问题提出了多因素模型连通可靠性仿真方法,同时结合可靠性定时标准实验方法给出了系统的移动Ad Hoc网络可靠性仿真实验设计方案。并根据具体移动Ad Hoc网络案例,在OPNET中进行二次开发建模与仿真,验证了该多因素连通可靠性仿真方法的可行性。Connectivity reliability of mobile Ad Hoc network is of great significance in many fields including battlefield command and control, rescue and relief work of police and medical department. However, most current connectivity reliability evaluation methods of Ad Hoe network are simple and unitary in consideration of practical modeling environmental factors, and OPNET simulation, as the representative of network simulation, is aimed simply at general performance,lacking reliability analysis of the network. Up to now this is no such a method that could implement comprehensive connectivity reliability evaluation of mobile Ad Hoc network involving node mobility in practical situation, characteristics of wireless communication and complex terrain environment. In light of this, a multi-factor connectivity reliability simulation method is proposed, and additionally, in combination with fix-time reliability test method, a simulation experiment scheme is also given. Meanwhile, the secondary development of modeling and simulation in OPNET is done in accordance with practical mobile Ad Hoc network cases, and the experiment indicates the feasibility of this simulation method.
