Hello, everybody.I would like to ask if anyone has tried to implemente Z-MAC 
protocol on NS2.26. I need your help.When I try to run "ns simple-wireless.tcl 
12  wirelessopt.tcl" ,a mistake occured ,the detail mistake is as follows:


 
num_nodes is set 12
ns:Mac/802_11 set ether_hdr_len_:can't read "ether_hdr_len_":no such variable
    (object set line 1)
    invoked from within
"Mac/802_11 set ether_hdr_len_"
   
Please help me ,thank you very much.
