Many sensor networks have lately included actuation as an important property of the nodes. With the introduction of actuation, new requirements are posed on these nodes in terms of reconfiguration of collaboration patterns. The sensors/actuators are very often connected to various heterogeneous hardware that have a few KBs of memory, low processing power and communication range, such as WSN motes...
A sensor, actuator, and device network (SADN) is composed of sensor, actuator, and device nodes. Sensor nodes sense physical events and send sensed values of the events to actuator nodes. Actuator nodes decide on proper actions on receipt of sensed values and then issue requests of the actions to the device nodes. We propose an SADN model where sensor, actuator, and device functions are replicated...
