[ns] Error in Simulation wired-cum-wireless

[dri.pnasc]

Hi !

I am simulating an wired-cum-wireless scenario (3 nodes thats server video,
voice and datas are linked in a router that is linked in another node.  This
last one is linked in a BS thats send the information to 3 receivers
mobilenodes without moving (SS).

In the 3 server nodes I attached:

  server node 1 (video) : udp / cbr
  server node 2 (voice): udp / cbr
  server node 3 (datas): tcp / ftp

 In the mobile nodes I attached:

 mobile node 1 ( receive video) :  null
 mobile node 2 (receive voice): null
 mobile node 3 (receive datas): sink


When I start the simulation appear the following error.  Someone can help
me??? whats these errors means?
