Wireless sensor actuator network for light monitoring and control application
Suet-Fei Li · 2006
Actuation is the less-studied aspect in wireless sensor actuator network (WSAN) research and few prototyping activities on actuation have been reported. We have prototyped a light sensing and actuation application motivated by the home environment. By developing the major components of a real deployment, we have gained first hand knowledge of the challenges and issues in WSAN and identified important areas for future research. We propose a heterogeneous architectural concept for WSAN which consists of sensors and actuators communicating in separate communication channels with different capacities, paradigms, costs and reliabilities. This architecture accommodates the characteristic differences of sensing and actuation, has the potential to fulfill the real time requirement of actuation while remaining low cost and low energy, and is relatively simple to implement.
