Smart Sensors and Actuators: A Question of Discipline
Hoel Iris, François Pacull · DOAJ (DOAJ: Directory of Open Access Journals) · 2013
Low power consumption and reliability are two important properties in the wireless sensor network area. The approach presented here to improve these aspects is to use a rule-based middleware enforcing a coordination protocol on top of the communication protocols imposed by the different wireless sensor networks. In addition, we move the callee side of this protocol from the gateway to the sensors/actuators in order to make them able to directly respond to this protocol. Then, it is possible to control from the application side the control (sleep/awake) of the sensors and the transactional processing of operations involving a group of sensors/actuators. This has a positive impact both on the consumption and the reliability. Examples illustrating our approach are presented.
