Localization is of great importance in mobile and wireless network applications. Time
Difference of Arrival (TDOA) is one of the widely used localization schemes, in which the …

We demonstrate a synchronization-free localization system, called Whistle, for wireless
sensor networks. The system is tested in several realistic environments on commercial off …

Multiple microphone devices aimed at hands-free capabilities and speech recognition via
acoustic beamforming require reliable estimates of the position of the acoustic source. Two …

This work addresses the problem of estimating the locations of multiple acoustic sources by
a network of distributed energy measuring sensors. The maximum likelihood (ML) solution to …

Long baseline microphone arrays, where the distance between single microphones is large,
is a cost-effective method to monitor activity in a large region of interest. The high range …

The Web Services Choreography Description Language (WS-CDL) is a newly developed
specification for Web services composition to describe the observable behavior across …

Wireless Sensor Networks (WSNs) are used in many industrial and consumer applications
that are increasingly gaining impact in our day to day lives. Still great efforts are needed …

An Energy-efficient Node Selection (ENS) mechanism has been proposed to improve the
localization precision of target tracking with low computational complexity and energy …

Localization of an isotropic source using energy measurements from randomly deployed
sensors is considered. In particular, an optimization problem that does not require …

In this paper we introduce a new multilateration-based method for source localization.
Sensors with known positions collect noisy signals whose strength depends on the relative …
