There is a problem with Random.rand() function in TOSSIM. The result of this
functions is always identical for each mote.
For example:
$ build/pc/main.exe -t=50 9
SIM: Random seed is 46875
4: Random: 25778
1: Random: 49743
2: Random: 30049
6: Random: 31429
7: Random: 6452
5: Random: 51923
3: Random: 38032
8: Random: 30743
0: Random: 24870
Exiting on SIGINT at 0:0:18.00713575.


$ build/pc/main.exe -t=50 9
SIM: Random seed is 906250
7: Random: 6452
4: Random: 25778
3: Random: 38032
5: Random: 51923
8: Random: 30743
1: Random: 49743
0: Random: 24870
2: Random: 30049
6: Random: 31429
Exiting on SIGINT at 0:0:12.04950600.

How can we generate different random number each time running program?
