Constant Velocity Mobility Model

[daviddvs]

Hi,

I have a problem when I try to use the mobilityType="ConstantVelocityMobilityModel" in LTE. I am trying to modify the coverage of the eNB (I reduce the value of homeEnbTxPower). With velocity=None configured, I get less coverage as far as I reduce the value of the Tx power. My problem turns up when I set a velocity value (non zero), the UE starts its movement and the coverage of the antenna stays invariable (it loses connectivity after about 30 km).
Furthermore, the same scenario works properly when I use WIFI instead of LTE.
Is there any reason for that behaviour?

Thanks.

Why not use the ConstantPositionMobilityModel？By the way, how do you set the speed of the ConstantVelocityMobilityModel?

I use ConstantVelocityMobilityModel because I need the UE to move at a certain speed.
Check this file ~/OpenNet/mininet/build/lib.linux-x86_64-2.7/mininet/lte.py and look for the addUe function. One of its parameters is the velocity, which is applied in case of setting the ConstantVelocityMobilityModel.

You can set the ConstantPositionMobilityModel for eNB, and the ConstantVelocityMobilityModel for UE.
