Abstract: An access method is executed by a multi-core processor system. The access method includes activating a driver that corresponds to a first CPU, based on a start of execution of a first application; starting measurement of an access time period, based on access of a peripheral device; outputting, when the access time period exceeds a predetermined time period, a detection signal to reset the driver; and prohibiting, when the access time period exceeds a predetermined time period, writing into a register retaining data to be written into the peripheral device from the first CPU.

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 given sensor node, upon determining that data processing requested by another sensor node cannot be completed by the given sensor node, selects a sensor node that based on hop count based information stored in a storage apparatus, is away from a receiver. The given sensor node transmits to the selected sensor node, request notification requesting execution of the data processing exclusive of an executable portion. The given sensor node executes the executable portion, upon receiving securement completion notification indicating that the execution of the data processing indicated in the transmitted request notification can be completed by at least one sensor node among plural sensor nodes.

Abstract: A computer obtains first information related to a first communication path that is from a first aggregating apparatus to a second aggregating apparatus when the second aggregating apparatus receives a transmission signal that is from sensor nodes in response to a transmission instruction that is transmitted by the first aggregating apparatus and propagated by multi-hop communication via the sensor nodes. The computer obtains from a storage apparatus, second information that is related to a second communication path that is a stationary path from the first aggregating apparatus to reception by the second aggregating apparatus. The computer determines correspondence of the first communication path and the second communication path by comparison of the first information and the second information, and if the first communication path and the second communication path do not correspond, the computer determines that an abnormality related to a sensor node is present.
