A wireless sensor network (WSN) has important applications such as remote environmental
monitoring and target tracking. This has been enabled by the availability, particularly in …

Locating the position of fixed or mobile sources (ie, transmitters) based on measurements
obtained from sensors (ie, receivers) is an important research area that is attracting much …

In this paper, we provide a theoretical foundation for the problem of network localization in
which some nodes know their locations and other nodes determine their locations by …

We present the design, implementation, and evaluation of BeepBeep, a high-accuracy
acoustic-based ranging system. It operates in a spontaneous, ad-hoc, and device-to-device …

Over the past decade we have witnessed the evolution of wireless sensor networks, with
advancements in hardware design, communication protocols, resource efficiency, and other …

How do animals use their habitat? Where do they go and what do they do? These basic
questions are key not only to understanding a species' ecology and evolution, but also for …

We consider the problem of estimating the geographic locations of nodes in a wireless
sensor network where most sensors are without an effective self-positioning functionality …

Environmental wireless sensor network (EWSN) systems are deployed in potentially harsh
and remote environments where inevitable node and communication failures must be …

Target tracking systems, consisting of thousands of low-cost sensor nodes, have been used
in many application domains such as battlefield surveillance, wildlife monitoring and border …

Determining node positions is essential for many next-generation network functionalities.
Previous localization algorithms lack correctness guarantees or require network density …
