[ns] accessing MAC cache_ array out of range

Hi,i m trying simulate wsn with mobility for 5 nodes using aodv routing protocol but getting this error. i have matched the coordinates of mobility pattern file with the node movement pattern in trace file and found that movement pattern assign tto node 0 is now assigned to node 5 and Node numbering starts from 1-5 for 5 nodes. i have assigned id 0 to the sink.
please guide how to resolve this issue..
Regards,Najma
