In sensor network applications, measured data are often meaningful only when the location
is accurately known. In this booklet, we study research problems associated with node …

In sensor network applications, the measured data makes sense only if the location is
known. The location of the node is known, and the wireless communication line and …

In this paper, localization using narrowband communication signals are considered in the
presence of fading channels with time of arrival measurements. When narrowband signals …

In this paper, the performance of different localization algorithms are compared in the
context of the sequential Wireless Sensor Network (WSN) discovery problem. Here, all …

This paper describes the design and implementation of a mobile application (app) for
acoustic ranging developed for the Android platform. The ranging strategy used is an …

A main challenge in target localization arises from the lack of reliable distance measures.
This issue is especially pronounced in indoor settings due to the presence of walls, floors …

A fully distributed algorithm for estimating the center and the radius of the smallest sphere
that contains a wireless sensor network is proposed. The center finding problem is …

In this thesis, effi cient methods are presented to calibrate large or small aperture array
systems containing different types of uncertainties. Specifically the challenge of reducing the …

Wireless sensor networks that consist of thousands of lowcost sensor nodes have been
used in many promising applications. Localization is one of the most important subjects …

Target localization is an important problem in signal processing and sensor networks, with
