Problems solved by technology

[0005] However, in the case where a terminal cannot perform data processing of its own terminal using its own terminal due to the hardware resources of the terminal, there is a possibility that the processing result cannot reach the device that performs processing based on the processing result of the data processing

Embodiment 2

[0108] Next, in Embodiment 2, a case where data processing is sequential processing will be described. In the case of sequential processing, even if the processing is delegated to a plurality of sensor nodes 101 in a distributed manner, it cannot be executed simultaneously. Therefore, in Embodiment 2, the number of sensor nodes 101 that can complete the data processing is ensured and the execution starts sequentially thereafter.

[0109] Figure 21 It is an explanatory diagram showing an example of request generation in the second embodiment. The sensing detection unit 502-0 performs sensing detection with a sensor. The judging unit 504-0 derives the throughput of data processing corresponding to the sensing detection event through the sensing detection unit 502-0. The throughput of data processing may be, for example, the number of all processing steps or the data size of data processing. Here the number of steps for all processes is 45. Furthermore, the judgment unit 50...

Abstract

The present invention relates to a communication device, system, and communication method. When it is judged that the execution of the data processing entrusted from the sensor node (101-x) cannot be completed by its own node, the sensor node (101-y) selects a remote receiver ( 102) Such sensor nodes (101). The sensor node (101-y) transmits a request notification to the selected sensor node (101) to request execution of data processing other than a part of executable data processing. If receiving the guaranteed completion notification indicating that at least one sensor node (101) in the plurality of sensor nodes (101) can complete the data processing shown in the sent commission notification, the sensor node (101-y) starts to execute the Part of the data processing performed.

Description

technical field [0001] The present invention relates to a communication device, system, and communication method. Background technique [0002] Conventionally, a system including a mobile terminal, a connection server that distributes content to the mobile terminal, and a control server that manages the location information of the connection server and the content is known. In this system, there is known a technique of predicting a destination of a mobile terminal and then delivering requested content to a connected connection server (see, for example, Patent Document 1 below). [0003] In addition, a sensor network (WSN: Wireless Sensor Networks) system is known in which a plurality of wireless terminals equipped with sensors are distributed in a predetermined space, and they can cooperatively extract the environment and physical conditions. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2004-221680 [0005] However, in a case where a terminal cannot perform da...
