In this thesis we investigate the problem of robustness and scalability w.r.t. estimating the position of randomly deployed motes/nodes of a Wireless Sensor Network
(WSN) without the help of Global Positioning System (GPS) devices. We propose a
few applications of range independent localization algorithms that allow the sensors
to actively determine their location with high resolution without increasing the complexity of the hardware or any additional device setup. In our first application we try
to present a localized and centralized cooperative spectrum sensing using RF sensor
networks. This scheme collaboratively sense the spectrum and localize the whole network efficiently and with less difficulty. In second application we try to focus on how
efficiently we can localize the nodes, to detect underwater threats, without the use of
beacons. In third application we try to focus on 3-Dimensional localization for LTE
systems. Our performance evaluation shows that these schemes lead to a significant
improvement in localization accuracy compared to the state-of-art range independent
localization schemes, without requiring GPS support.
