Desperate for help.. (NS-2.34)

Hello,I'm having trouble with a tcl script for AntNet in WSNs. i tried a simple topology of 3 nodes. It seems like it's working (in NAM) but the file containing the routing table (rtable.txt) is generated empty. i don't know if there's something wrong with my TCL script or my C++ code for AntNet protocol. I have tried before this AntNet in wired network and it worked fine, generating trace files and full routing table at each node. Can anybody help me? Here's my TCL script:
