摘要

Problems with communication interface selection control using a fluctuation control equation are that it is difficult for the control to address large environmental variations and that the control requires parameter adjustments according to environments, which incurs operating cost. A communication method according to the present invention includes the step of observing communication environment conditions to generate communication environment data, generating fluctuation information by using the communication environment data as the data occurs, and allocating communication resources by performing attractor selection control on the basis of the fluctuation information. The step of generating fluctuation information comprises the step of using a fluctuation equation to perform fluctuation equation control utilizing the fluctuation information as the fluctuation information occurs. The fluctuation information is not fluctuation terms that are independent random noise terms in the fluctuation equation but include a fluctuation term reflecting the communication environment data.
