【摘要】：近年来,EXata仿真软件在无线网络仿真领域得到了越来越多的重视,除了独立进行网络仿真之外,它还可以与其他软件配合进行大系统的仿真实验。节点移动是影响无线网络性能的重要因素,EXata支持多种移动模型,但这些模型都是在仿真开始前依据预定的规则产生节点移动轨迹,无法对节点的移动进行实时控制,影响了其在大系统仿真实验中的应用。该文设计并实现了一种EXata实时控制移动的模型,可以利用UDP通信实时接收移动指令并控制仿真节点的移动,同时提出原地踏步策略解决了EXata软件位置管理模块未开放所导致的节点必须连续运动的问题。仿真结果表明,所提移动模型可以实时控制中大规模无线网络中仿真节点的准确移动。
[Abstract]:In recent years, more and more attention has been paid to the simulation software of EXata in the field of wireless network simulation, except for the independent network simulation. It can also cooperate with other software to carry out large-scale system simulation experiments. Node mobility is an important factor affecting the performance of wireless networks. Exata supports a variety of mobile models. However, these models can not control the movement of nodes in real time because they are generated according to the predetermined rules before the start of the simulation. This paper designs and implements a EXata real-time mobile control model, which can use UDP communication to receive mobile instructions and control the movement of simulation nodes. At the same time, the standing in situ strategy is proposed to solve the problem that the nodes must move continuously due to the lack of opening of the EXata software location management module. The simulation results show that. The proposed mobile model can control the accurate movement of simulated nodes in large scale wireless networks in real time.

【正文快照】： 1概述在进行产品开发或者新技术推广时,仿真是降低难度和成本的重要手段,由于可以兼顾成本与仿真的真实性,半实物仿真近些年得到了越来越多的重视。EXata是基于Qualnet仿真内核的一种半实物仿真软件,其创建的“虚拟网络”完全可以与真实物理网络中的所有组件互相通信和交换数
