Examination of efficient aggregation method of sensor information by wireless sensor network for event detection in frequency sharing

Abstract

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. In this paper, we propose an event-driven access control system that notifies the user when the Received Signal Strength Indicator (RSSI) exceeds a certain level, in order to detect the radio wave usage of the existing system. In this paper, we propose a new method of access control based on cluster partitioning. In this paper, we studied an exploratory data aggregation method for each sensor group using cluster division. In this paper, we propose an exploratory data aggregation method for each sensor group using cluster division.
