SSD: A Robust RF Location Fingerprint Addressing Mobile Devices' Heterogeneity
TLDR
We derive analytically a robust location fingerprint definition, the Signal Strength Difference (SSD), and verify its performance experimentally using a number of different mobile devices with heterogeneous hardware. Expand

Aloha-Based MAC Protocols with Collision Avoidance for Underwater Acoustic Networks
TLDR
In this paper, we study the performance of Aloha-based protocols in underwater networks, and propose two enhanced schemes, namely, Aloha with collision avoidance (Aloha-CA), and Aloha -AN, which are capable of using the long propagation delays to their advantage. Expand

TLDR
We provide an elaborate discussion on Bluetooth signal parameters with respect to localization, whereby we collectively designate all types of Bluetooth specification parameters that are related to signal strength - such as RSSI, Link Quality, Received and Transmit Power Level - as Bluetooth signal, parameters.
