Optimal Actuation Strategies for Sensor/Actuator Networks [PDF]
2006 Third Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services, 2006 Wireless sensor-actuator networks (SANETs), in which nodes perform actions (actuation) in response to sensor measurements and shared information, have great potential in medical and agricultural applications. In this paper, we focus on the problem of using distributed sensed data to design actuation strategies in order to elicit a desired response from
