Summary:
In recent years, dynamic frequency sharing using radio sensors to observe radio wave usage has been attracting attention in response to the shortage of frequency resources. When the radio sensor detects the radio signal strength indicator over the certain threshold, it informs the RSSI to the data center. It is an event-driven access control system. The authors have previously proposed a three-step information aggregation method for event-driven access control. In the proposed method, the data center selects the cluster composed of multiple sensors for informing the sensing data to it. For deciding the selection of cluster, the prior-measured RSSI tendency is used but the suitable spatial resolution for evaluating the prior-measured RSSI tendency has not been decided, yet. In this paper, we investigate the spatial resolution suitable for evaluating the trend of pre-measured RSSI.
