A Distributed Sensor Data Stream Delivery System with Communication Loads Balancing for Heterogeneous Collection Cycle Requests

Due to the prevalence of sensors such as live cameras or environmental sensors, sensor data stream delivery, which requires continuous and cyclic data delivery attracts great attention. For sensor data stream delivery, various communication loads balancing techniques have been studied since the load of the sensor data source become high to accommodate large number of clients. However, these studies assume only the requests that have the same collection cycle, which is not enough for the actual applications. In this paper, we propose a sensor data stream delivery system with communication loads balancing for heterogeneous collection cycle requests. The proposed system distributes the loads by re-delivering the sensor data that are requested by other clients with different collection cycles but have common cycles.
