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. Our researching team proposed methods to distribute communication loads in the case of delivering the sensor data stream that have different data delivery cycles. In the proposed methods, source nodes and destination nodes consist P2P overlay network, and communication loads are distributed by re-delivering the sensor data that have the same delivery time. In addition, we evaluated the proposed methods by simulation in an environment where specific source node delivers single sensor data stream. In this paper, we evaluated the existing methods by simulation in an environment which has multiple sensor data streams.
