An information processing device comprising: a communication unit configured to perform exchange of a signal for generation or updating of a multi-hop communication path using wireless communication with another information processing device ; and a control unit configured to perform control to change a metric value included in the signal being a path request message based on a state of the information processing device, wherein changing the metric value comprises adding an estimated or a computed device metric value to the metric value of the metric field of the received path request message; wherein, when data transmission to the information processing device which is designated as the next transmission destination on the communication path is performed, the control unit is configured to compute the device metric value by converting transmission-rate value; wherein, when the device metric value is computed after a re-setting of a low-pass filter, the control unit is configured to estimate the device metric value for a predetermined number of transmitted packets based on a current electric field intensity which is further converted to an estimated transmission rate value which is further converted to the estimated device metric value; and subsequently after a given number of packets have been transmitted from the information processing device after the re-setting of the low pass filter the transmission rate value is obtained by averaging the rate value resulting from averaging the transmission rate of the succeeded transmitted data through the low-pass filter and the estimated transmission rate converted from the current electric field intensity, wherein the rate of the data at which transmission has succeeded being loaded into the low-pass filter as an initial value. a communication unit configured to perform exchange of a signal for generation or updating of a multi-hop communication path using wireless communication with another information processing device ; and a control unit configured to perform control to change a metric value included in the signal being a path request message based on a state of the information processing device, wherein changing the metric value comprises adding an estimated or a computed device metric value to the metric value of the metric field of the received path request message; wherein, when data transmission to the information processing device which is designated as the next transmission destination on the communication path is performed, the control unit is configured to compute the device metric value by converting transmission-rate value; wherein, when the device metric value is computed after a re-setting of a low-pass filter, the control unit is configured to estimate the device metric value for a predetermined number of transmitted packets based on a current electric field intensity which is further converted to an estimated transmission rate value which is further converted to the estimated device metric value; and subsequently after a given number of packets have been transmitted from the information processing device after the re-setting of the low pass filter the transmission rate value is obtained by averaging the rate value resulting from averaging the transmission rate of the succeeded transmitted data through the low-pass filter and the estimated transmission rate converted from the current electric field intensity, wherein the rate of the data at which transmission has succeeded being loaded into the low-pass filter as an initial value. <EOS>
