摘要： A wireless communication device 81 operates in either a ROD mode or a non-ROD mode. The non-ROD mode sets the state of the device to an active state that the device can perform wireless communication compliant with a first communication scheme with a communication destination device 82. The ROD mode: sets the state of the device to either the active state or a sleep state that the device can receive an activation instruction signal compliant with a second communication scheme requiring smaller electric power to receive a signal than the first communication scheme and cannot perform wireless communication compliant with the first communication scheme with the communication destination device; sets the state of the device to the sleep state when a predetermined sleep condition is satisfied; and sets the state of the device to the active state when the device receives the activation instruction signal.

摘要： A packet interval (a time difference between sequentially received packets) in a certain previous time is calculated and a cumulative distribution function of the calculated packet interval is obtained. Meanwhile, a function value-corresponding to-flow end that is a boundary value of the cumulative distribution function to be considered as a flow end (timeout) in the range of a cumulative distribution function value is stored. From the cumulative distribution function obtained as described above, a value of a packet interval mapped to a cumulative distribution function value that matches the function value-corresponding to-flow end is set as a threshold. That is, the threshold is dynamically set based on a previous packet interval. Therefore, a packet stop period from a last packet reception time to a current time is measured, and it is detected as a flow timeout at a timing when the measured value is equal to or greater than the threshold.
