A Load Distribution Method Based on Distributed Hashing for P2P Sensor Data Stream Delivery System

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. Currently, the methods to distribute communication loads by relay nodes in the case of delivering the sensor data streams that have different data delivery cycles are proposed. However, in the existing methods, since the specific node builds delivery paths and notifies to the related nodes, the delivery paths are necessary to be built and notified again when nodes join or leave. Therefore, in this paper, we propose a method which determines relay nodes based on distributed hashing and constructs delivery paths autonomously by each node. We evaluated the effectiveness of proposal in simulation.
