Abstract

Due to the prevalence of sensors such as security cameras or environmental sensors, sensor data stream delivery which means delivering the sensor data every cyclic collection attracts great attention. For sensor data stream delivery, various methods to distribute communication loads in the case of delivering the same sensor data streams to multiple clients have been studied. Although these methods assume that the sensor data streams have the same data collection cycles, data collection cycles sometimes differ. Hence, we propose a method to distribute communication loads in the case of delivering the sensor data stream that have different data collection cycles. The proposed method distributes communication loads by re-delivering the sensor data that have the same collection time but are included in different sensor data streams.
