This article presents a study on the nodes positioning confidence in mobile
collaborative scenarios. The confidence of nodes positioning is an indicator
that allows providing appropriate services and information to mobile users. In
mobile ad-hoc networks, nodes with positioning capabilities could share their
position with their neighbors in order to allow these latter to determine their
own location collaboratively and increasing their positioning confidence. We
study the fluctuation of this confidence in mobile scenarios populated by nodes
with and without positioning capabilities. We analyze the effect of changing
the maximum communication range of the nodes, the amount of nodes with
positioning capabilities present in the environment. We also studied the impact
that produces the degree of nodes mobility. The findings of this study are
presented and discussed.
