Abstract

Abstract : This paper focuses on a sensor network virtualization over multidomain sensor network and proposes an abstraction called "logical sensor network (LSN)" for sensor data processing. In the proposed abstraction, processing is a directed acyclic graph that consists of nodes and streams, which represents a small data processor and communication rules between them, respectively. We have added a notion of a trigger to this graph. A trigger represents a timing of the process execution. We have implemented the middleware named LSN-Middle to run a virtualized sensor network and proved its feasibility.
