Title: "Exploiting Node Mobility for Wireless Sensor Networks"

by

Mr. Ji LUO


Abstract:

A fundamental evolution is witnessed in recent research and
development of wireless sensor networks: the capabilities of the
sensor nodes have gone broader beyond a static sensing device; and now
they include node mobility. In this proposal, we present our current
research status on exploiting node mobility in wireless sensor
networks. We first investigate the impact of node mobility on
localization which is the fundamental issue in mobile sensor networks.
By leveraging different types of relative distance constraints, we
propose a distributed and range free Mobile Inequality Localization
(MIL) algorithm, which is quickly re-localizable when all sensors are
moving uncontrollably. With location awareness, we further analyze
several unique issues in mobile sensor networks. One issue is about
the coverage with mobile sensor nodes. By introducing the concept of
probabilistic coverage, we develop a basic platform to provide the
realtime coverage status for a given region. In addition, we address a
double-mobility problem in coverage and propose a distributed protocol
SSC to collaborate between controllable and uncontrollable mobility to
maintain the coverage. The other issue is about the event collection.
By leveraging the spatial-temporal correlation of events, we propose
an online scheme for mobile nodes to selectively collect event
information. We also present an intelligent approach to design
feasible path for mobile sinks. Several ongoing and future works
include: building a testbed for measuring the energy usage in
buildings, and investigating how to improve the energy efficiency for
green buildings where the personnel and some assets are mobile.
