Wireless Sensor and Actuator Networks for Lighting Energy ...

Chapters four through six present the theoretical development of bridging
wireless sensor/actuator networks and lighting systems. Chapter four details the sensor
validation and fusion technology developed for guaranteeing pertinent sensory
information from networked and redundantly deployed wireless sensors. Chapter five
proposes the sensing strategy that adapts the sensing rate to the change of the stimulus,
the daylight, so as to facilitate more efficient sensor data acquisition and wireless
communication. Chapter six describes the algorithm for lighting actuation, which
optimizes energy usage and satisfies occupants’ lighting preferences.
Chapters seven through nine depict the implementation and verification of the
developed system. Chapter seven details the design of wireless light sensors and
actuators as well as the initial implementation of the wirelessly enabled lighting system
on a prototyping luminaire structure. Chapter eight describes the implementation of
both the research lighting system and a representative commercial lighting system in a
small private office and compares various aspects of systems on human subjects.
Chapter nine presents a larger scale implementation in a shared-space office in which
real occupants work on a daily basis and demonstrates potential energy savings that
could be achieved with the research lighting system.
Chapter ten concludes the dissertation with detailed discussions of the
contributions and commercial implications of this research and points out future
research directions that could build on the research presented in this dissertation.
