TITLE:: Instrumented Sensor System Architecture
AUTHOR:: Dekhil, Mohamed
AUTHOR:: Henderson, Thomas C.
ABSTRACT:: Sensor systems are becoming ubiquitous throughout society, yet their
design, construction and operation are still more of an art than a science.  In
this paper, we define, develop, and apply a formal semantics for sensor systems
that provides a theoretical framework for an integrated software architecture
for modeling sensor-based control systems.  Our goal is to develop a design
framework which allows the user to model, analyze and experiment with different
versions of a sensor system. This includes the ability to build and modify
multisensor systems and to monitor and debug both the output of the system and
the affect of any modification in terms of robustness, efficiency, and error
measures. The notion of {\em Instrumented Logical Sensor Systems} (ILSS) that
are derived from this modeling and design methodology is introduced.  The
instrumented sensor approach is based on a sensori-computational model which
defines the components of the sensor system in terms of their functionality,
accuracy, robustness and efficiency. This approach provides a uniform
specification language to define sensor systems as a composition of smaller,
predefined components. From a software engineering standpoint, this addresses
the issues of modularity, reusability, and reliability for building complex
systems.  An example is given which compares vision and sonar techniques for
the recovery of wall pose.
