understand leach.out

walaa_ali22 · 05-03-2015, 03:29 AM

when running leach. i got different leach.out
first i was confusing is it correct or no.

for example, one of them show that there is a collision. some times one TDMAschedule.txt file generated and some times more than one.

every time i run leach_test the out put differ. but i notice that in coditions.txt ==> the desired number of clusters is always 1

first, how can i change this value. and how it will effect on leach.out?

second, i need some illustration on how to understand leach.out to be able to determine it is correct or not.

thanks in advance

Simulations will often output a new result by every run.
Just like in a real world situation.
Ns-2 has some inbuilt random functions, e.g. "seed".

"num_clusters=1" :

Code:

$ grep -in clus leach_test
4:#This is the algorithm that we are going to run. Type leach, leach-c, stat-clus or pegasis
18:# number of clusters we want.  It is recommended to use 5% of the total for LEACH and LEACH-C
19:# WARNING! - It is important to use 1 cluster for Pegasis
21:num_clusters=1
49:-num_clusters $num_clusters \

The numbers are the 'line numbers'.
I.e. you can try with a change in leach_test, line 21.

"least_test" is the main script for the simulations settings.
Please read all lines in least_test.
