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： A sensor node (101-k) detects an occurrence of sensing (ev) and judges whether data processing corresponding to the sensing (ev) will finish before an occurrence of sensing (ev) subsequent to the sensing (ev), based on a time interval when the occurrence of the sensing (ev) is detected. When determining that the data processing will finish, the sensor node (101-k) executes the data processing and transmits the execution result of the data processing to a first apparatus (101-1) directly communicable with the sensor node (101-k). When determining that the data processing will not finish, the sensor node (101-k) transmits, to the first apparatus (101-1), request information causing the first apparatus (101-1) to execute the data processing and to transmit the execution result of the data processing to a second apparatus directly communicable with the first apparatus (101-1).

摘要： A determining apparatus (110) obtains distance information that indicates distances between monitoring apparatuses (121 to 128) provided to encompass a given area in which wireless communications apparatuses (102) are scattered. The determining apparatus (110) causes a wireless signal to be transmitted and received between monitoring apparatus (121 to 128) by multi-hop communication among the wireless communications apparatuses (102). The determining apparatus (110) calculates an estimated distance between the monitoring apparatuses (121 to 128), based on the hop count of the wireless signal multi-hop communicated among the monitoring apparatuses (121 to 128). The determining apparatus (110) makes a determination concerning a vacant area (103) in which no wireless communications apparatus of a given area (101) is present, based on the distance indicated by the distance information and the calculated estimated distance.

摘要： A sensor node (101-1) has no subsequent assignment-destination sensor node (101), when the execution of data processing is assigned to a sensor node (101-h) that can directly communicate with a parent device (102) (dashed-lined arrow), and the data processing is not completed by the assignment-destination sensor node (101-h). Thus, when unable to execute the data processing, the sensor node (101-1) requests a sensor node (101-m) that requires plural hops in communicating with the parent device (102) (solid lined arrow). Even when the data processing is not completed by the assignment-destination sensor node (101-m), the data processing can be completed by executing the data processing in stages by plural sensor nodes (101).

摘要： A communications apparatus (102) transmits a registration request for a reference hop count. Each node (101), when receiving the registration request, obtains and registers as a reference hop count, the hop count of the registration request. Each node (101), when transmitting to the communications apparatus (102), data measured by a sensor, adds the reference hop count to the sensor data. The communications apparatus (102) receives the sensor data transmitted from each node (101), compares the actual hop count of the received sensor data and the reference hop count added to the received sensor data, and determines whether failure has occurred at a given node (101) included in a node group (101s).

摘要： When a sensor node (101-5) has a large power consumption, an information processing apparatus (100) propagates a portion of request information for a data process having the request recipient set to a sensor node (101-7), through a path that does not pass through the sensor node (101-5). For example, the information processing apparatus (100) changes a division rate at a sensor node (101-3) acting as a branching point for the request information for the data process having the request recipient set to the sensor node (101-7) to thereby change the distribution of the transferred data amount and equalize the power consumption of the sensor nodes (101) in a sensor network.

摘要： A first OS (1) dispatches a first thread to a first CPU. The first OS (2) compares the access frequency of shared resources by the first thread and a first threshold. The first OS (3) judges a dependence relationship between the first thread and a second thread under execution by a second CPU. Upon that the access frequency is greater than the first threshold and that no dependence relationship exists (marked by x), the first OS (4) changes the setting of a clock generating circuit so that the phase of the clock to be supplied to the first CPU and the phase of the clock to be supplied to the second CPU are opposite to each other. The first OS (4) changes the setting of the clock generating circuit so that the frequency of the clock to be supplied to the shared resources will be twice as great as the frequency of the clock to be supplied to the first CPU.
