问题
I'm a MRs student , i use sumo 0.25.0 and veins 4.4 within omnet++ 5.0 .I'm working in the IEEE0802.11p module. Including my proposition i will use a formula that change the transmission range calculator into dynamical calculator which communicate with the simulation to get information from it like (mean speed, average distance from front-bumper to front-bumper between vehicles ...).
here is the transmission range formula that I will use and the Article containing the formula
my question is where can i find the transmission range calculator and where can I put my code in the application layer or in the mac layer?
Ps:I already read all the topics about the transmission range in veins here and in the google group but I can't find a response.
回答1:
Veins does not use the concept of a transmission range (in the sense of a fixed range that vehicles can communicate - sometimes also called a unit disk radio model). Instead, Veins compares usable received power to noise and interference, then (based on this ratio) derives a probability of packet reception.
See related questions (and answers) for questions revolving around how to set (and use) the transmit power:
- how to set the transmission range of a node under Veins 2.0?
