SATI: Scalable And Traffic efficient data dissemination Infrastructure for sensor-based distributed information services

Abstract

When highly distributed data streaming services are fully realized, they will bring up new issues in delivering data streams to data consumers. First, data delivery scheme should be traffic efficient because the Internet can be easily inundated by a massive number of data streams. Also, the probing messages generated by many delivery schemes waste network resources. These problems are not easily solved by existing data delivery schemes because none of them consider the economic usage and measurement of network resource. This paper proposes SATI, an infrastructure that provides not only shared management and measurement of network information but also scalable and traffic efficient data delivery. Experimental results show that SATI is scalable and greatly reduces network traffic. I
