如何基于静脉中的两辆车之间的距离来控制传输功率和速度 [英] How to control the transmission power and speed based on the distance between two vehicles in Veins
问题描述
我是有关静脉的初学者.现在，我正在尝试基于两辆行驶中的车辆彼此之间的距离(静脉4.5，Omnet 5.0和Sumo 0.29)来模拟它们之间的传输功率和速度的动态调整. 到目前为止，我已经建立了Sumo模型并在Omnet中运行该模型，但是没有任何编程，这意味着两辆车之间的传输功率和速度都已在.ini文件中设置.现在，我想实现一种算法来动态调整它们. 作为一个初学者，我几乎不知道如何开始这项工作. Veins教程没有告诉您如何应用Veins提供的功能.我现在基于.ned文件构建一个新的.cc文件.从MyVeinsApp.cc，我发现了一些我需要实现的方法.但是我仍然需要一些有关我的问题的编程说明. 1如何获取两辆正在行驶的车辆之间的实时距离? 2是否可以通过静脉4.5控制传输功率和速度?
I am a beginner about Veins. Now I am trying to simulate dynamic adjustment of the transmission power and speed between 2 running vehicles based on their distance with each other with Veins 4.5, Omnet 5.0 and Sumo 0.29. So far I have built the Sumo model and run the model in Omnet but without any programming which means the transmission power and speed between 2 vehicles are all set in the .ini file. Now I want to implement an algorithm to adjust them dynamically. As a beginner I barely know how to start this job. The Veins tutorial didn't tell how to apply the functions provided by Veins. I now build a new .cc file based on our .ned file. And from MyVeinsApp.cc I found some methods I need to implement. But still I need some programming instructions about my problem. 1 how to get the realtime distance between 2 running vehicles? 2 is it possible to control the transmission power and speed with Veins 4.5?
对于这些最初的问题我感到很抱歉.但是我真的不知道如何从一开始就在编程级别上逐步开发Veins模拟
I am sorry for these initial questions.But I really don't know how to develop a Veins simulation from the very beginning step by step at the programming level
非常感谢！
推荐答案
要获取两辆车之间的距离，可以使用
To get the distance between two vehicles you can use the built-in function distance() from Coord (see this post).
To control the transmit power you can use the parameter txPower from Mac1609_4.
要更改车辆的速度，您可以查看此帖子.
For changing the speed of the vehicle you can check this post.
