[ns] having problem in Link layer issues

I am trying to modify LEACH code, which is a cluster-oriented sensor network
protocol. It uses CDMA technique, using different code for each
cluster-node/cluster-head-node communication and cluster-head-nodes/Base
Station (BS) communication. In the protocol the CHs (cluster head nodes)
communicate directly with the BS, while I am trying to let the CHs
communicate with other CHs before reaching BS, i.e. hop-by-hop communication
between CH-BS link.
But when I try to send the packet from one CH to the other nearest CH, other
CH doesnot receive it. Rather it is lost somewhere in the Link Layer (ll)
methods which are scheduled by the cluster head at one point. I could not
figure out link layer methods, how they work, which methods they call, they
schedule further uptarget_ and downtarget_ instances, which I could never
Can anybody help i this regard? How to track this uptarget_ and downtarget_
instances defined in ll.h and ll.cc?
waiting eagerly for any help.
