摘要

3维移动Ad hoc网络(3-D MANET)是一种网络场景分布于3维空间的移动Ad hoc网络.链路动态性分析是研究3-D MANET的一项基础性工作,其结论可作为网络协议设计的基础.该文基于CV(Constant Velocity)移动模型,从概率模型的角度推导出了链路寿命期望和分布的数学表达式,并通过仿真实验进行了验证,表明了理论计算结果的正确性.结论对3-D MANET的研究和应用具有一定的参考价值.%3-Dimensional Mobile Ad hoc NETwork (3-D MANET) is a case of mobile Ad hoc network which is distributed on the 3-Dimensional space. Analysis of link dynamics is a fundamental issue in the studies of 3-D MANET, the conclusion of which can be the basis of the design of network protocol. Based on the Constant Velocity (CV) mobility model, analytical expressions of expected link lifetime and its distributions are derived from a probability model. Simulation results verify the accuracy of the analytical expressions. The conclusion is valuable for the research and application of 3-D MANET.
