Abstract:
1. A wireless communication apparatus comprising: a generation unit configured to generate traffic information corresponding to an application program for data communication, the traffic information including a data rate; a request unit configured to request an access point to perform an addition of a traffic stream, using the traffic information generated by the generation unit; a communication unit configured to perform data communication wirelessly based on the addition of the traffic stream; a measurement unit configured to measure data amount of the traffic stream actually transmitted to the access point by the communication unit; a calculation unit configured to calculate an excess ratio of an allocated communication bandwidth to a calculated communication bandwidth on basis of the data amount measured by the measurement unit, and a predetermined data amount to be transmitted; a changing unit configured to reduce the data rate included in the traffic information based on the excess ratio; and a re-request unit configured to re-request the access point to reserve a communication bandwidth using the reduced data rate.
