Positioning of nodes

[remo mein]

Hi all,

I am currently learning to program wireless sensor network simulation using omnet++ 5.0. Naturally, i started with Tic Toc examples and now in wireless tutorials of Inet 3.4.

I had edited the simulation so that i can change the number of nodes by making it as a parameter. However, i find that the nodes get positioned outside the canvas as shown in the attached figure. I want them to be within the grey background.

I had attached my .ned and .ini files. Kindly help.

Regards,

Muru
