Distributed Environment Control Using Wireless Sensor/Actuator Networks for Lighting Applications

We propose a decentralized algorithm to calculate the control signals for lights in wireless sensor/actuator networks. This algorithm uses an appropriate step size in the iterative process used for quickly computing the control signals. We demonstrate the accuracy and efficiency of this approach com...
