OMNET ++中的结果分析 [英] Results Analysis in OMNET++

问题描述

我正在将Veins框架与OMNET ++一起使用，以模拟高速公路场景.

I am using Veins framework with OMNET++ to simulate a highway scenario.

我正在使用cOutVector来收集实验结果.

I am using cOutVector to collect the results from my experiments.

我有1000多个节点(车辆)，并且cOutVector分别为每个模块(节点)收集结果.但是，我需要收集总体结果.

I have more than 1000 nodes (vehicles), and the cOutVector collects results individually for each module (node). However, I need to collect the overall results.

例如，所有节点接收了多少个信标?反正有收集这样的结果吗?

For example, How many beacons were received by all nodes? Is there anyway of collecting such results?

推荐答案

在OMNeT ++中，输出结果可以保存为两种不同的类型，因此可以保存为文件格式:

In OMNeT++ the output results can be saved in two different types, and thus, file formats:

1. 标量(*.sca)-包含整个模拟运行的摘要数据(平均值，总和，计数，最大值，最小值)
2. 向量(*.vec)-包含模拟运行每一秒的细粒度数据(以时间序列的形式)

1. Scalars (*.sca) - contain summary data (mean, sum, count, max, min) for the whole simulation run
2. Vectors (*.vec) - contain fine-grained data (in form of time series) for each second of the simulation run

输出文件格式与OMNeT ++的statistic机制紧密结合.统计信息允许您存储不同的结果记录模式，例如:计数，总和，均值，向量.

The output file formats are tightly coupled with the statistic mechanisms of OMNeT++. The statistics allow you to store different result recording modes, such as: count, sum, mean, vector.

在您的情况下，您需要查看每个节点的sum.

In your case you would need to look at the sum for each of your nodes.

@statistic[foo](record=count,mean,vector);

这些OMNeT ++机制在开始时似乎很复杂，但是一旦您扎紧脑袋，它们就很容易了.此外，它们非常强大，可为您模拟的许多方面提供见解.

These OMNeT++ mechanism seem complicated in the beginning, but they are rather easy once you wrap your head around. Also, they are very powerful giving insights to many aspects of your simulations.

不幸的是，在不知道您的代码的情况下，不可能为您的情况提供即用型"解决方案.

Unfortunately, it is impossible to provide a "ready-to-use" solution for your case without knowing your code.
