How to do the simulation about LTE in the hexagonal grid layout.

[kcy7...@gmail.com]

Hi, everyone

I try to create a heterogeneous networks topology.

The topology comprising 7 cells/ 21 sectors is deployed for the macro cell and 4 pico cells are uniformly located within each macro sector.

The Heterogeneous-Network.cc is my program.

I use the LteHexGridEnbTopologyHelper to create the network topology and the netanim-module to generate topology.xml.

Then I use the netanim to open the topology.xml, the result is the topology.png.

The position of some enb is not the expected results, they are deployed at the same position.

Can anyone tell me where is wrong of my program?

The other question is how to deployed the pico cell in each macro sector?

Thanks.

Hi,

LteHexGridEnbTopologyHelper places 3 eNBs per site, one for each sector. This could explain why you see some eNB at the same position. For the picocells, to allocate then randomly within each sector you would need a RandomHexagonPositionAllocator which unfortunately is not implemented (patches welcome!).

sorry to cut in the middle of you both, got this link from Mr. John Abraham
so Nicola, no hexagonal depiction in NetAnim then ?

Sorry for the request, I saw your code, which configuration did you use for Pico cells? Can you help me?

Hi, Chinyen,

I am new to ns3 simulator. Just trying to run the example code "star-animation.cc".

The simulator generates xml file but I do not know how to convert it to .png file so that I may view the star topology. You have done it for your scenario.

Can you please help me?

Thanks

Hi Nicola, does the LteHexGridEnbTopologyHelper place the eNodeBs like the topology in the picture below?

Is this ns3 program ???

Hi, you should change GridWidth into 3
