Wireless Sensor and Actuator Networks for Lighting Energy ...

possibility of wireless actuator networks, which uses wireless sensor network
technologies for actuation.
This dissertation also shows the feasibility of the wireless networked lighting
system through the implementations during the research, and it demonstrates the
possibility of delivering satisfying lighting while minimizing energy usage. The
wireless-integrated lighting components promise a lower retrofitting cost and hence a
shorter payback period that is more likely to meet the five-year payback period criterion
acceptable to facility managers for adopting energy efficient products [15].
Furthermore, the ability to simultaneously minimize energy consumption and satisfy
each occupant’s lighting preferences points to the potential of the system being widely
adopted to generate savings.
