In this paper, the authors focus on a sensor network virtualization over multidomain sensor network and propose 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. They have added a notion of a trigger to this graph. A trigger represents a timing of the process execution. They have implemented the middleware named LSN-middle to run a virtualized sensor network and proved its feasibility.
