2025年3月8日 · To support distributed simulation in ns-3, the standard Message Passing Interface (MPI) is used, along with a new distributed simulator class. Currently, dividing a simulation for distributed purposes in ns-3 can only occur across point-to-point links.

后来从官网上下了ns3.35的官方版本，加上--enable-examples和--enable-mpi选项编译了一下可以通过。 后面查到可以通过 ./waf --no-task-lines -v 命令（参考链接如下），看到编译中实际所用的命令。

`NS3-model-library` 是一个针对网络仿真工具 NS-3 的模型库，它包含了多种模块化的组件以帮助研究人员和开发人员进行复杂的网络仿真任务。该文档提供了 NS-3 模型库的组织结构概述。 #### 动画 (Animation) 在 NS...

• Distributed NS-3 uses MPI for communication and synchronization • Message Passing Specification (not the library itself) – Point-to-Point as well as collective communications

•Distributed simulation in ns-3 allows a user to run a single simulation in parallel on multiple processors •By assigning a different rank to nodes and connecting

Ns-3 parallel simulation: Ns3 offers the message passing interface (MPI) along with the distribute simulator class for this purpose of parallel simulation; Parallel simulation involves the execution of a single simulation program on a collection of tightly couple processors; Goal of parallel simulation in …

2024年10月6日 · 二，ns-3配置MPI. ns-3 在大规模拓扑仿真中，为加速仿真速度，可以利用MPI工具，实现分布式多进程联合仿真。 1，配置ns-3的文件 sudo gedit /etc/profile 在文件最后加入一行路径为ubuntu系统安装openmpi的路径; 一行ns-3的安装路径

2021年6月18日 · 通过ns-3中的新MPI接口，可以轻松地处理在LPs之间发送接收消息的过程。 除了在LPs之间传递简单的消息外，还在每个LP上使用分布式模拟器来确定要处理哪些事件。

2017年5月4日 · After building ns-3 with mpi enabled, the example programs are nowready to run with mpirun. Here are a few examples (from the root ns-3 directory): $ mpirun -np 2 ./waf --run simple-distributed $ mpirun -np 4 -machinefile mpihosts ./waf --run 'nms-udp-nix --LAN=2 --CN=4 …

2011年3月21日 · In this paper, we describe the results of simulation of very large (up to 10 9 nodes), planetary-scale networks using ns-3 simulator. The modeled networks consist of the small-world core graph of network routers and an equal number of the leaf nodes (one ...
