Abstract(in English) | The development of WBAN channel models requires a lot of experiments and simulations. In order to reduce the number of experiments and simulations, this research group has proposed a concept of WBAN channel modeling method using human motion as a parameter. However, although we have studied the method of generating the human posture model for the simulation calculation related to this method, the measurement of human motion and channel by experiment has not been conducted yet. Therefore, we developed a human motion-receiver signal strength synchronization measurement system to acquire the human motion information and the received signal strength(RSSI) of the whole body during a specific motion, synchronized by motion capture(MOCAP) and wireless equipment(BLE), for the purpose of using it for the experiment of parameterization of human motion. The synchronization operation for synchronizing MOCAP and BLE and the data processing method for synchronization were studied, and it was confirmed that the synchronization measurement can be performed well. We also verified the operation of the measurement system and the possibility of channel modeling based on human motion parameters. Using the measured human motion and RSSI data, we predicted the RSSI of the future time based on the past human motion using two machine learning methods, RNN(Recurrent neural network) and LSTM(Long short-term memory). As a result, it was found that the RSSI in the future can be predicted to some extent from the past values of human body movements. If we can predict the future RSSI variation, it will lead to the modeling of channel variation, and the above results confirm the possibility of channel modeling. |
