Hi... I am trying to run vertical handover simulation between wifi and wimax using NIST module. but when i run example code ( which is in directory ns2.29/tcl/hsntg/wimax/handover-wifi-wimax) i will get error "node 6 is not defined". when i searched in google i came to know that the initial position of node 6 is not defined and we have to add code $ns initial_node_pos $node_number value I got same problem in some other program and i did same method and it worked there. but its not working. How to solve? Thanks in advance, Payaswini
