Research Thrusts
This project mathematically characterizes
structural dynamic properties of sensor networks
in order to engineer their design and operation for
dependable information fusion in urban operations.
Four research thrusts address our comprehensive
approach towards formulating an engineering science
for operational dependability of sensor networks
in this context.
I. Modeling of Sensor Networks
Rigorous mathematical modeling that captures
the structural dynamics of the network is essential
for engineering and verification of performance.
Effects of network structure on fusion processes
are captured through symbolization and hierarchical
abstraction in the information space. Following
the Joint Director of Laboratories Fusion Model,
we will model the information space as layers of
discrete event dynamic systems with increasing
abstraction. We define symbolization and abstraction
mechanisms at each layer to retain the predictability
of the ensemble of sensor information.
Our approach makes both critical elements of
structural design. This is done through the construction
of a hidden Markov model and its in-situ
approximations. Structural design components of
interest include: coverage, connectivity, resilience,
diversity, permissiveness, and scalability. We will
formulate these analytically and experimentally
design measures for their deviation from normalcy.
Products of this thrust include a three-tiered set
of simulators of increasing fidelity and complexity
that capture the essential dynamics of sensor
networks. Other products are data generators, and
analyses and data management tools.
