hi all, i am trying to send packets from one mobile node in domain 1t o sink node in domain 2... but i get route to base station not found error... this is the code .... # set global variables #set nb_mn [lindex $argv 0] ;# max number of mobile node set packet_size 1500 ;# packet size in bytes at CBR applications set output_dir . #set gap_size 1 ;#compute gap size between packets #puts "gap size=$gap_size" set traffic_start 5 set traffic_stop 120 set simulation_stop 8 set diuc 7 ;#modulation for MNs
