[ns] LEACH Cluster Heads not receiving any message
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

[ns] Problems when simulate two Base-Station in the same scenario
Hi, everyone!
I am doing a job to simulate a scenario with 2 BS, 2 mobile nodes each
in one BS's domain respectively, and the 2 BS connected with a wired
node. I describe it below: D-A-B-C-E, DE are two mobile nodes,
AC are two Base-stations and B is the wired node. I need to build 3 TCP
links: D->A, D->B, D->E.
As in my script, I find D->A, D->B is normal while there is no TCP
connection between D and E through D->A->B->C->E. Could anyone can help
me on this?
Thanks in advance!
My script is below:
