WIRELESS COMMUNICATION DEVICE, IoT DEVICE, CONTROL METHOD, AND PROGRAM

To suppress the occurrence of an unnecessary waiting time for retransmission timeout during data transmission by a first wireless communication method with high communication speed, and suppress unnecessary data retransmission during data transmission by a second wireless communication method with slow communication speed.SOLUTION: A wireless communication device includes a wireless communication unit that selectively uses a first wireless communication system and a second wireless communication system whose maximum communication speed is slower than the first wireless communication system to perform wireless communication, a retransmission processing unit that performs data retransmission processing on the basis of a retransmission timeout setting value when data is transmitted via the wireless communication unit, and a switching unit that switches the retransmission timeout setting value according to a wireless communication method used in the wireless communication unit such that the retransmission timeout setting value at the time of data transmission by the second wireless communication method is longer than the retransmission timeout setting value at the time of data transmission by the first wireless communication method.SELECTED DRAWING: Figure 4 【課題】通信速度が速い第１無線通信方式によるデータ送信時における再送タイムアウトの無駄な待ち時間の発生を抑制するとともに、通信速度が遅い第２無線通信方式によるデータ送信時における無駄なデータの再送を抑制する。【解決手段】無線通信装置は、第１無線通信方式と最大通信速度が前記第１無線通信方式よりも遅い第２無線通信方式とを選択的に用いて無線通信を行う無線通信部と、前記無線通信部を介したデータ送信時に再送タイムアウトの設定値に基づいてデータの再送処理を行う再送処理部と、前記第２無線通信方式によるデータ送信時の再送タイムアウトの設定値を前記第１無線通信方式によるデータ送信時の再送タイムアウトの設定値よりも長くするように、前記無線通信部で用いる無線通信方式に応じて前記再送タイムアウトの設定値を切り替える切替部と、を備える。【選択図】図４
