Claims (9)

A communication device interface that transmits data via a communication path that is mutually established by wireless communication with another communication device that belongs to the first network and is located above,
A path change permission determination function unit that determines whether the communication path can be changed based on a predetermined condition;
When the communication path for constructing the first network is determined based on the result of measuring the communication performance in the communication path, and the path change permission determination function unit determines that the path change is necessary A first network communication control unit for changing the communication path and reconstructing the first network;
A communication device comprising: The route change permission determination function unit, the data tolerance value determining processing data transmission amount to determine a change in the communication path to be less than the data tolerance of the data transmission completion in the past, the communication path that has changed in the past past performance confirmation process of determining a change in the communication path based on the results, or the change of the communication path based on the network reconfiguration time required to change the communication path reconstructing the first network The communication apparatus according to claim 1, wherein at least one determination process among the network reconfiguration time determination processes for determining whether the predetermined condition is satisfied. Further, by the communication path of the second network constructed with the management server for managing the configuration of the first network, the communication information of the first network, and from the other communication device that is subordinate the communication device according to collected the data to claim 1, further comprising a communication control function unit that transmits to the management server. The data allowable value determination process performed by the path change permission determination function unit obtains the data transmission amount for each data type of the data transmitted to the other communication device, and the data transmission amount in unit time is the data allowable amount The communication apparatus according to claim 2, wherein the communication apparatus determines that the route change is necessary when the value is smaller than a value. Further, the data allowable value determination process performed by the path change permission determination function unit is performed when the data transmission amount is smaller than the data allowable value, and the continuous communication in a predetermined period requested for transmission from the other communication device. transmitting data communication apparatus according to claim 4 is a process of determining that the data transmission amount of the data transmission request is needed the route change if less than the data tolerance. In the past performance confirmation process performed by the route change permission determination function unit, the degree of the route change performed during a predetermined period exceeds a degree threshold, the content of the route change performed during the predetermined period, and the past the communication apparatus according to claim 2 and results of the route changes made in the same period predetermined period is a process of determining that it is necessary to the route change if similar. The network reconfiguration time determination process in which the route change permission determination function unit performs, the determined variations in the number of hops based on the change factor of the network topology of a first network, without change in the number of the hops, the number of the hops reduction in the order of increase in the number of the hops, the communication apparatus according to claim 2 priority is a process for determining low for the route change. Transmitting and receiving data via a communication path that belongs to the first network and is mutually established by wireless communication with another communication device;
Based on a predetermined condition, and determining whether to change the communication path,
Based on the result of measuring the communication performance in the communication path, it determines the communication path for constructing the first network, when it is determined that it is necessary to reroute, change the communication path the communication method comprising the steps of: reconstructing the first network. A plurality of communication devices belonging to the first network, and a management server belonging to the second network,
The communication device
A communication device interface for transmitting and receiving data via a communication path mutually constructed by wireless communication with other communication devices;
Based on a predetermined condition, and the route change permission determination function unit that determines whether to change the communication path,
Based on the result of measuring the communication performance in the communication path, when the first to determine the communication path for constructing a network, it is determined that it is necessary to reroute the path change permission determination function unit, change the communication path, the first network communication control unit to reconstruct the first network,
Via the second network constructed between the management server to manage the configuration of the first network, to the management server, communication performance of the communication path of the first network, and a communication control function unit for transmitting the data,
Have
The management server
Communication system the second through the network, receiving a communication performance, and the data of said communication path of said first network from said communication device.
