Localization is a fundamental problem in wireless sensor networks. Current localization
algorithms mainly focus on checking the localizability of a network and/or how to localize as …

We consider node localization problems in ad hoc wireless networks in which two types of
nodes are considered: nodes with self-locating capability like GPS and nodes with no self …

Localization is an essential task in Wireless Sensor Networks (WSN) for various use cases
such as target tracking and object monitoring. Anchor nodes play a critical role in this task …

In recent times, wireless sensor network (WSN) finds their suitability in several application
areas, ranging from military to commercial ones. Since nodes in WSN are placed arbitrarily …

Abstract In Wireless Sensor Networks (WSNs), main challenges which restrict the
performance are data computation, lifetime, routing, task scheduling, security, organization …

As event detection is one of the main purposes of using wireless sensor networks (WSNs),
the nodes location is essential to determine the location of that event when it occurs. Many …

Several applications have exploited wireless sensor networks (WSNs), and localization is a
key WSN technology. The range-free localization technique is substantially less expensive …

Many applications that use sensor data from a wireless sensor network (WSN) require
corresponding node position information as well. Therefore, it is not surprising that a …

Node localization is a difficult task in sensor networks in which the ranging measurements
are subject to errors and anchor positions are subject to uncertainty. In this paper, the robust …

An unknown-position sensor can be localized if there are three or more anchors making time-
of-arrival (TOA) measurements of a signal from it. However, the location errors can be very …
