Sensor networks normally have redundancy for sensing coverage. Some sensors are allowed to sleep while preserving network functionality. Sensors that are randomly placed in an area should decide which of them should be active and monitor an area, and which of them may sleep and become active at a later time. The connectivity is important so that the measured data can be reported to a monitoring center. Sensor area coverage problem has been considered for both the unit disk graph and physical layer-based sensing models. Actuators may similarly run a protocol to decide about their service areas, releasing some of them from particular duty. Operational range assignment for both sensor and actuator nodes is also discussed.
