I'm working on OMNET + + Veins within the framework, I set the property of the RSU. Ned file is as follows:
@ the display (p=150140;" B=10, 10, oval; R=90 ");
Tkenv show RSU around a circle, but the vehicle received within the scope of beacon (circle),
How to adjust the RSU transmission range to the Circle?

Add a r display string tags just add a circle to the graphical output; It does not affect simulation,
If the definition of "range" to receive the probability of zero points, can according to the antenna transmission power and the sensitivity of radio (all in omnetpp. Ini setting) this point, as follows: model and the use of path loss and decline (in?? Set up in 3210), if you change these parameters and models, you will change the "range",
However, please note that this range with only minimal correlation with frame reception probability, intravenous use MiXiM suite and approach to transport modeling for path loss and decline effect (for example, caused by building both random and deterministic) to modify the signal power of two-dimensional (time) and frequency function, if the frame of the received power higher than the sensitivity threshold, depending on the signal to interference and noise of the function division receives probability calculation, thus SINR is derived, and thus calculate the bit error rate, even in the middle level of the interference, this also means that even if they are far above the threshold sensitivity (just because of their low SINR) can decode most frames,
Just repeat: I warned not to calculate any purpose other than pure information "range", theoretically, how far can you send in a moderately busy channel with you how many distance has nothing to do, send on this effect is modeled after intravenous!
