[ns] NS2.27 + LEACH installation problem.

[sstl vls]

Hello all,

Iam trying to install and run LEACH on ubuntu6.06.  I followed the procedure  from the site: http://tmtam.wordpress.com/2007/07/31/installing-ns-227-and-leach-extension-on-ubuntu-704-feisty-fawn/
and  encountered the following problems on ./test:



./test

num_nodes is set 3

1.....  Why is this happening?




I guess the problem is with the inclusion of Phy/WirelessPhy channel. Where is it located in the ns2.27 folder? How do I verify if it is present?  N How do I include it?


When I execute validate, I get ‘the outputs deviate from standard
results’. Can you tell me where the problem lies?  




2.  Also once the GCC 4.1.x: ns-2.27-gcc410.patch  patch is applied, nrlsensorsim extension for ns 2.27 is showing problems on installation. I had to omit that. 

3. Do I have to install 802.15.4 layer support separately to simulate sensor networks? How do I do it?


Kindly help. It
is extremely important to me.
