Does anybody happen to have some good reference for this one? Something
like: "The failure of poisson modelling of mobile wireless links" or
What I have seen so far, simply assumes the contrary and uses Gilbert
Markov Models and the like.
Actually, this fails to model even a scenario where a user is waiting
for a bus at the bus station and talking to someone else with his mobile
and walks around a bit, one step to the left (broken connection) or to
the right (excellent connectivity).
Although this seems rather obvious to me, I don't know a paper, or a
well accepted text book, which explicitely states that Gilbert Markov
Models and the like are theoretically appealing, but do not reflect reality.
I would appreciate any hint here.
