A question about the 3-dimension mobility model in ns-3

[yytsk...@gmail.com]

Hi,

I want to implement the 3D mobility model in ns-3. However, the document of the mobility model says that

Note that in ns-3, movement along the Z dimension is not supported.

It is in the part of ns-2 MobilityHelper. I also checked the document of ns-2 and found that the third dimension (Z) is not used in ns-2.

Now I am confused. Is ns-3 not supported 3D mobility or it's just a mistake of the document?

The document could be get from:

https://www.nsnam.org/docs/release/3.27/models/html/mobility.html#ns-2-mobilityhelper

Please help.

Hello Yating,

The documentation is poorly worded.  That statement is copied verbatim from the ns2 mobility trace documentation.  

ns-3 supports 3D mobility, cf. the classes which derive from MobilityModel.

In fact the ns-3 class Ns2MobilityHelper does read z coordinates and do the right thing.

Wow, wonderful!. 

Thanks a lot.
