A Scalable Dissemination Network Architecture for Real-time Sensing Data Delivery
Yunseok Rhee · 한국정보기술학회논문지 · 2012
When highly distributed sensor networks are fully realized, they will bring up new issues in delivering sensing data streams to data consumers in real-time. Such a data delivery scheme should be traffic efficient because the Internet can be easily inundated by a massive number of data streams. This paper proposes a scalable data dissemination network architecture (SDNA) that provides not only shared management and measurement of network information but also traffic efficient data delivery. The SDNA basically organizes a hierarchical cluster based on a virtual layer over the Internet. It can significantly reduce the amount of data traffic by establishing a commonly shared delivery path to multiple consumers on the cluster structure.
