摘要
为有效指导三维环境中的移动自组织无线网络(MAWN)的部署并提高其可靠性,充分考虑节点移动特性,将节点在二维环境下的移动拓展到三维环境,构建了一种新的三维环境中节点移动模型(3D_NMM),在该模型基础上,提出了一种基于增量Dt的动态可靠性度量方法。仿真验证了方法的有效性和可行性,实验结果表明该方法能在Q×O(n2)时间内计算出MAWN的可靠性。
In order to deploy Mobile Ad-Hoc Wireless Network（MAWN） effectively in 3-D environment and improve its reli- ability, the Nodes Mobility Model（NMM） in 2-D environment is expanded to 3-D environment. A NMM in 3-D environment is established（3-D NMM）, in which the nodes mobility characteristic is fully considered. A novel At -based dynamic MAWN reli- ability evaluation method is proposed. The simulation results show that the MAWN reliability could be calculated within the time Q . O（n2） .
