hi all, I'm using NS2.29 with mannasim patch. i'm trying to run leach from the mannasim package. Everything seems to be running fine and the simulation also runs till the end. But the result says : "Warning! There are no nodes in cluster" for all the cluster heads. Each cluster heads clusterNodes_ list is empty. I edited leachapp.cc to broadcast message from a node after cluster heads have been selected, but all nodes except the ones being cluster heads receive this message. Even sending a message particularly to cluster head doesnt work. Also No cluster head receives the JOIN request sent by other nodes. It seems cluster heads aren't able to receive. I also noted that the node, before being selected cluster heads receives messages perfectly. Plz help. Thanks
