Ok I'll translate that error message to something more meaningful for english speakers in the next release ;-) This error occurs when a Packet Error Rate value cannot be found for some PHYMode. The common reason for the error is that you did not load the correct Packet Error Rate table into an instance of a PER object. In the adhoc_tcp.tcl script this is done using the following command: set per [new PER] $per loadPERTable80211gTrivellato but that table is for 802.11g modes only. If you try, e.g., to use Mode1Mb in the same simluation script, you'll get the error you mentioned. In dei80211mr we provide also a PER table for 802.11b, which is loaded using this command: $per loadPERTable80211bIntersilHFA3861B You can also define your own PER table if you wish. Just have a look at src/per_table_*.tcl to see how to do it. The last four values for each row are: PHYmode packetsize SNR(dB) PacketErrorRate Regards, Nicola
