Title: Connectivity and Localization in Wireless Sensor Networks
Abstract: Recently, a great interest is devoted to wireless ad hoc
networks, in particular to wireless sensor networks (WSN). WSNs are
composed of a large numbers of low-cost, low-power, densely
distributed, and possibly heterogeneous sensors. WSNs have a wide
range of application areas such as battlefield surveillance,
environment or health monitoring, and disaster relief operations. In
these applications, WSNs are used for a variety of tasks such as
detection, recognition, localization and tracking of objects or
events of interest. In this talk, I will describe firstly some
recent work on the statistical study of network connectivity, which
expresses a global property of the system as a whole: can
information be transferred through the network? Then, a localization
algorithm for an unknown number of sources given some quantized data
obtained at the fusion center from different sensors with imperfect
wireless channels will be presented.
