Due to the prevalence of sensors such as security cameras or environmental monitoring, sensor data stream delivery which means delivering the observed data continuously 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 delivery cycles, data delivery cycles sometimes differ. Hence, we propose a P2P-based method to distribute communication loads in the case of delivering the sensor data streams that have different data delivery cycles. The proposed method distributes communication loads by redelivering the sensor data that have the same delivery time but are included in different sensor data streams. We evaluated the effectiveness of the proposal in simulations and confirmed the load distribution in the case of many receivers at the same time.
