TCL script in NS2(pls clear this error)

Hi, I wrote a TCL script which involves running multiple sessions in NS2. The voice data is sent under UDP and the video data is sent under TCP. multiple calls start and end at each node at specific time. When I compile this program am getting a warning saying Warning: Route to base station not found: dropping packet. Am attaching the program with this mail. I want to get rid of the warning. Please let me know as soon as possible. Thanks ----------------------------------------------------------------------------------------------------- Installation: I have installed ns-allinone-2.31(used the patch files of ns-2.28). I installed ns-allinone-2.31 on ubuntu 8.10. The program involes 4 wired and 4 wireless nodes with 4 wired nodes connected to router and the router connected to base station which transmits the data to the wireless nodes. This is the scenario of the program. with this message am attaching the error log question??????? run ns-2.34/tcl/test/[login to view URL] ns [login to view URL] wireless2 How can you increase the number of nodes? Try to set AddrParams parameters: AddrParams set def_clusters 4 AddrParams set def_nodes 20 or maybe others... i can pay 20$ pls help me
