Abstract: When a first sensor node has a large power consumption, an information processing apparatus propagates a portion of request information for a data process having the request recipient set to a second sensor node, through a path that does not pass through the first sensor node. For example, the information processing apparatus changes a division rate at a third sensor node acting as a branching point for the request information for the data process having the request recipient set to the second sensor node to thereby change the distribution of the transferred data amount and equalize the power consumption of the sensor nodes in a sensor network.

Abstract: A sensor node among sensor nodes that synchronously switch between a first state and a second state transmits an abnormality notification signal to a collecting apparatus when in the first state and an abnormality occurs at the sensor node. The sensor node, when in the second state, transmits to the communications apparatus, a data signal that differs from the abnormality notification signal. During each interval of the first state, the sensor node enters a third state during a first partial interval of the interval of the first state, and receives and transfers an abnormality notification signal transmitted by another sensor node among the sensor nodes. During each interval of the first state, the sensor node further enters a fourth state during a second partial interval of the interval of the first state and different from the first partial interval, and refrains from receiving the abnormality notification signal.
