My central question at the moment is: Do we have stationary packet 
delivery times on mobile wireless links?

I was pointed to some papers, where those delivery times are estimated 
with EWMA filters.
May I be honest? I absolutely hate academic lying. When a delivery time 
is not stationary, I cannot estimate it using an EWMA filter.
(For EWMA filter fans: If you simply use "15" as the result for your 
EWMA filter, you have much less work and the result is as wrong as the 
original ;-))

To my understanding, it simply is not reasonable to expect stationary 
delivery times here. But I'm trying to get a sound answer for this 
question for about a year now, and I don't find sound literature nor do 
I find someone to answer my question.

Perhaps, this list is not the right place for my question, I would 
appreciate hints. However, I would like to find an answer to my question.
