Description: Estimating the positions of sensor nodes is a fundamental and
crucial problem in ad hoc wireless sensor networks (WSNs).
In this paper, an accurate node localization method for WSNs
is devised based on the weighted least squares technique with
the use of time-of-arrival measurements. Computer simulations
are included to evaluate the performance of the proposed
approach by comparing with the classical multidimensional
scaling method and Cram´ er-Rao lower bound. Platform: |

Description: Monitoring applications define an important
class of applications used in wireless sensor networks.
In these applications the network perceives
the environment and searches for event
occurrences (phenomena) by sensing different
physical properties, such as temperature, humidity,
pressure, ambient light, movement, and presence
(for target tracking). In such cases the
location information of both phenomena and
nodes is usually required for tracking and correlation
purposes. In this work we summarize most
of the concepts related to localization systems for
WSNs as well as how to localize the nodes in
these networks (which allows the localization of
phenomena). By dividing the localization systems
into three distinct components — distance/angle
estimation, position computation, and localization
algorithm — besides providing a didactic
viewpoint, we show that these components can
be seen as subareas of the localization problem
that need to be analyzed and studied separately. Platform: |

Description: Localization in wireless sensor networks is the process of determining the geographical positions of
sensors. Only some of the sensors (anchors) in the networks have prior knowledge about their geographical
positions. Localization algorithms use the location information of anchors and estimates
of distances between neighbouring nodes to determine the positions of the rest of the sensors. Platform: |

Description: Wireless sensor networks (WSN) have attached a great attention in the last few years. WSN
offer several advantages over the traditional sensor networks, such as elimination of costly
wires, security and larger area coverage. In the last few years, there has been great interest
commercial applications based on Ultra Wideband (UWB). It has potentially low complexity,
low cost and an excellent time domain resolution which facilitates location and tracking
applications. Platform: |
