How to get speed of mobile node veins_lte ?

[Amelie]

Hello,

I'm checking for some way to get a speed (m/s) of a car in veins_lte, i found the method : getCurrentSpeed() but it return a coordinate.

If anyone can help me.

Thank you.

I'm not intimately familiar with Veins LTE, but I guess the Coord class is simply used here to produce a speed vector (given in meters per second) that has components for both the x and y direction.

To check, observe the values of cars. If they are reading (13.9 m/s, 0 m/s) when a car is driving east and (-13.9 m/s, 0 m/s) when a car is driving west, you have confirmed this.

Best,

Christoph
