    摘要: A given node among nodes (#1) to (#6), ..., (#N) determines whether the contents of data obtained by a sensor of node (#1) as a first node and the contents of data obtained by a sensor of node (#2) as a second node are equivalent. If the contents of the data are determined to be equivalent, the given node among nodes (#1) to (#6), ..., (#N) suspends the transmission by node (#2), of the data obtained from the sensor of node (#2).

    摘要: A sensor node (101-i) is assumed to be able to execute any one among a first operation by which another sensor node (101) is requested to execute data process and if the request is not accepted the sensor node (101-i) starts executing the data processing after waiting for charging and a second operation by which the sensor node (101-i) starts executing the data processing after waiting for charging, without requesting the data processing to be executed. The sensor node (101-i) compares an expected value of a first time that elapses until execution is started by the sensor node (101-i) or the other sensor node (101) when the first operation is executed, and a second time that elapses until execution is started by the sensor node (101-i) when the second operation is executed. Based on the comparison result, the sensor node (101-i) executes among the first operation and the second operation, the operation for which the time that elapses until execution is started is shorter.

    摘要: A position estimation apparatus (100) acquires, for base devices (102), the number of hops from a target sensor node (101) to a base device (102). The position estimation apparatus (100) calculates, for each base device (102), a distribution of estimated distances corresponding to the total hops, based on the number of hops and a distribution of estimated distances stored in a storage device (110). The position estimation apparatus (100) calculates, for each base device (102), a distribution of estimated positions within a given region (A), based on the distribution of estimated distances, information concerning a range of the given region (A), and information concerning a position of the base device (102). The position estimation apparatus (100) calculates an index that indicates a probability of a position of the target sensor node (101) within the given region (A), based on the sum of distributions of estimated positions concerning the base stations.

    摘要: Access contention for a shared resource (106) is resolved while suppressing power consumption in an information processing system (100). A bus controller (108) using a cache miss detecting unit (119), detects first information that indicates with respect to a CPU (101) and a CPU (102), a cache hit or a cache miss. The bus controller (108) using a high-speed I/O detecting unit (120), detects second information that indicates an activated state or a non-activated state of a DMA controller (103) and a DMA controller (104). The bus controller (108) using a generating unit (123), generates a setting signal based on the first information and the second information.

    摘要: In a memory access controller (202), a classifying unit (302) classifies a CPU (#0) to CPU (#3) into a first group of CPUs having made an exclusive access request to a shared memory (201) and a group of CPUs not having an exclusive access request. Subsequently, in the memory access controller (202), a detecting unit (303) detects a CPU having completed exclusive access among the first group of CPUs, and a notifying unit (304) sends to a core standing by for exclusive access among the first group of CPUs, a notification of release from a state of standby.
