[ns] AODMV problem

Hi all, I am using AOMDV. I have plotted graph for different performance metrics(such as packet delivery ,end-end delay,normalised routing load and route discovery frequency). I have less pdr and more nrl for AOMDV. But expected is more pdr and less nrl for AOMDV than aodv. can anybody tell me
