TO the NS-USERS community,
Although i believe that i will get a reply even after so many attempts in posting these questions to the NS users Community and still not getting any help.Also after knowing that their are so many experienced Ns-users in this mailing list who have at some point in time successfully implemented LEACH,but still no one would come forward to help or even give a hint. I have lost all hope and most probably will have to look into other research areas maybe altogether stop using NS-2 for my WSN simulations even after spending so much of my time on it. If any of the users stumbled upon the same problem or know a possible solution plz look into this as this is my last cry for any help or guidance to this forum. I am trying to implement leach on NS-2.29 using mannasim and for quite a long time i am stuck with this problem. The following error occures while running leach on Mannasim. It would be of great help if anybody knows any other way and has successfully implemented LEACH on NS2(any version) using any other alternatives available. <-----------------> [r...@localhost bin]# ./ns leach.tcl Initializing MannaSim Script...
