AbstractIn this paper, we present two practical ARQ-Based security schemes for Wi-Fi
and RFID networks. Our proposed schemes enhance the confidentiality and
authenticity functions of these networks, respectively. Both schemes build on
the same idea; by exploiting the statistical independence between the multipath
fading experienced by the legitimate nodes and potential adversaries, secret
keys are established and then are continuously updated.AROMA: Automatic Generation of Radio Maps for Localization Systems.

AbstractWLAN localization has become an active research field recently. Due to the
wide WLAN deployment, WLAN localization provides ubiquitous coverage and adds
to the value of the wireless network by providing the location of its users
without using any additional hardware. However, WLAN localization systems
usually require constructing a radio map, which is a major barrier of WLAN
localization systems' deployment. The radio map stores information about the
signal strength from different signal strength streams at selected locations in
the site of interest.
