Abstract:
In a network system, an own subsystem recognition unit is provided in each of subsystems, and holds a state and a function of the own subsystem. A shared information communication unit acquires states and functions of the subsystems. An objective acceptance unit accepts a setting of a target state. A shared storage unit stores knowledge regarding a combination structure of functions of the respective subsystems necessary for realizing the target state. A structure setting unit automatically sets a combination structure of functions of the respective subsystems, including determining whether the function of each of the subsystems is to be activated, based on the target state, states and functions of the subsystems, and the knowledge regarding a combination structure. A role determination unit determines functions to be executed by the respective subsystems based on the automatically set combination structure. A role notification unit notifies the subsystems of the determined respective functions.
Abstract:
A module transmits send information to be processed by an information processing apparatus along a transmission path on which the information processing apparatus is present. When the send information is sent in accordance with predetermined sending parameters, if a sending failure in which a sending completion state of the send information cannot be confirmed occurs, a part or all of the sending parameters used for sending of the send information with respect to which the sending failure has occurred are changed, and the send information is resent in accordance with the sending parameters after the changing. Then, the predetermined sending parameter changed between the occurrence of the sending failure and confirmation of the sending completion state of the resent send information, and resend result information related to a send result corresponding to the changed predetermined sending parameter are acquired and sent toward a predetermined processing apparatus.
Abstract:
A coordinator (10) includes an accepting unit (11), a required resource information calculation unit (13a), an insufficient resource information calculation unit (13b), a combination determination unit (14), and a communication unit (18). The required resource information calculation unit (13a) calculates information regarding resources required to satisfy a request accepted by the accepting unit (11). The insufficient resource information calculation unit (13b) compares the required resources calculated by the required resource information calculation unit (13a) with resources included in each of a plurality of sensor nodes (30, 40, 50), and calculates information regarding an insufficient resource that each sensor node lacks. The combination determination unit (14) determines a combination of resources required to satisfy the request, based on the information regarding the insufficient resource calculated by the insufficient resource information calculation unit (13b).
Abstract:
When a status of communication between a first transmission module and a second transmission module that is located downstream of the first transmission module on a predetermined transmission path is output, received signal strength information is output for each piece of send target information in order of transmission, and regarding this output, an interval between output of received signal strength information associated with send target information transmitted immediately before transmission of one piece of send target information and output of received signal strength information associated with the one piece of send target information corresponds to a transmission period of the one piece of send target information from the first transmission module to the second transmission module. This makes it easy to grasp a status of communication between arbitrary transmission modules in a network in which information is transmitted sequentially via a plurality of transmission modules along a predetermined transmission path.
