Module
description:
Localization is an important service for WSNs,
because many WSN applications require location information of the sensor
nodes. Furthermore, localization turns out to be a challenging task for WSNs.
We first give a high-level picture of localization and a classification of
existing localization protocols - range-based and range-free localization. We
then introduce a Minimum Mean Square Estimation (MMSE) based localization
solution, because MMSE based solutions can summarize the basic ideas of most
localization schemes. In the course modules, we use simple mathematics to
show basic ideas of MMSE.
Based on MMSE, we then introduce the secure localization problem and one
popular solution to provide correct location given malicious attacks. We show
how to derive a set of consistent location references and illustrate how to retrieve
a set of good location references.
