Abstract (inglese)

In this paper we address the problem of localizing, tracking
and navigating mobile nodes associated to operators acting in a ?xed
wireless sensor network (WSN) using only RF information. We propose
two alternative and somehow complementary strategies: the ?rst one is
based on an empirical map of the Radio Signal Strength (RSS) distribu-
tion generated by the WSN and on the stochastic model of the behavior
of the mobile nodes, while the second one is based on a maximum like-
lihood estimator and a radio channel model for the RSS. We compare
the two approaches and highlight pros and cons for each of them. Fi-
nally, after implementing them into two real-time tracking systems, we
analyze their performance on an experimental testbed in an industrial
indoor environment.
